Abstract:	Individual layers representing coastal inundation (flooding) for different sea levels, at 0.2 m increments up to RL 5 m (Moturiki Vertical Datum 1953). Designed for use in Waikato Regional Councils Coastal Inundation Tool.
Statement:	This raster dataset comprises individual layers representing coastal inundation depths for specific sea levels. The sea levels used are in 0.2 m increments and range from 0.8 m to 5.0 m (relative to Moturiki Vertical Datum 1953). Note that the first mapped water level for all locations shows the area that is likely to be inundated with a high tide (generally 0.2 m below the MHWS water level). All higher mapped water levels only show areas that would not normally be inundated by a high tide. Data is presented as raster files which show inundation depth for connected areas (where water could flow directly to the sea) and disconnected areas (below or at the water level but may have no direct flow path to the sea). Disconnected areas may still be affected by coastal inundation in some way, e.g. via groundwater.
Other Information:	The coastal inundation layers were generated using a LiDAR derived Digital Elevation Model (DEM), which is generally accurate to around ±0.2 m vertically. The LiDAR survey does not identify all features that allow water to flow through (e.g. culverts), or are barriers to water flow (e.g. flood walls or sheet piling). Thus, manual modification of the DEM for specific areas was undertaken to ensure the DEM generally represented the hydraulic regime, especially for areas with flood protection, such as the Hauraki Plains. Therefore, the green disconnected inundation areas may or may not be ‘real’ and could actually be connected inundation areas. The disconnected inundation areas should still be regarded as areas that could be affected in some way by coastal inundation. More information on the limitations of the data is available in the Coastal Inundation Tool User Guide: https://www.waikatoregion.govt.nz/assets/WRC/Services/regional-services/hazards-and-emergency-management/coastal/Coastal-Inundation-Tool-V2-User-Guide.pdf

Abstract:	Aerial and satellite imagery data that show the inundation extent of previous major river flood events in 1958 (Waipa River - about and south of Otorohanga), 1998 (lower Waipa and Waikato Rivers) and 2004 (Waipa and Tongariro Rivers).
Statement:	This data is presented as raster imagery (1958, 1998 and 2004) which shows the inundation extents of previous major river flood events. The imagery data for each event only covers particular areas.
Other Information:	For further enquires please contact the Regional Hazards team. The 2004 satellite imagery for Waipa River is DigitalGlobe pan-sharpened 0.6m resolution orthorectified imagery orginally sourced through Sinclair Knight Merz (SKM). More information can be found on this imagery in historical WRC metadata here https://liveapps.wairc.govt.nz:8443/ords/live/f?p=135:2:3788287621127::NO::P2_METADATA_ID:847

Data Use Limits :	The 1958 and 1998 imagery is historical aerial photo tif tiles that have not been orthorectified or mosaiced. As such they are less accurate, slow to load and difficult to share. The 2004 DigitialGlobe satellite imagery of the Waipa River is licensed using terms that only allow WRC to share the data with "1-5 user groups (organisations, government/defence/ educational departments etc.), globally)". As such, the imagery is unlikely to be able to be shared publicly without approaching Jacobs Solutions Inc., who acquired SKM in 2014, or Maxar Technologies who acquired DigitalGlobe in 2017.

Abstract:	River flood depth for the 1% annual exceedance probability (AEP) event for a number of rivers and streams, derived from local flood modelling. Contains depth values, thus to be used for technical purposes.
Statement:	River flood depth for a 1% annual exceedance probability (AEP) event, derived from 2D local flood modelling. To determine the potential flood depth, the flood level data was reclassified into flood depth above ground level (from LiDAR data) in meters. Data is presented as integer raster files showing potential flood depth, and can be used for technical analysis. Raster VALUE field = depth m. Attribute information includes the year the modelling was completed (from ~2006 onwards). Models have incorporated the best available information at the time of their creation, generally including (but not always) LiDAR data, and flood event survey assessments. A climate change component is generally included in the modelling and will likely be based on the best available MfE guidance from the period of modelling. All flood depth information takes into account the presence of WRC-managed stopbanks and floodwalls, with the exception of Tararu and Te Puru (which have been modelled using a “stopbanks down” approach). The LiDAR data is converted to a grid which has limitation when assessing small stream channels and topographic features such as ridges. This may lead to minor discrepancies in water flows which may lead to limitations in defining flood extents. Internal drainage such as storm water systems, culverts, piping etc, are generally not included in the modelling. Depending on how the model is configured, they often only consider the main watercourse, so flooding of minor channels, tributaries, ponding and coastal inundation may not be represented by the flood extent.
Other Information:	For further information, including the model limitations for a particular area, please contact the Regional Hazards team or Technical Services team.

Abstract:	River flood depth for the 1% annual exceedance probability (AEP) event for Tararu and Te Puru, derived from local flood modelling using a "stopbanks down" scenario. Contains depth values, thus can be used for technical purposes.
Statement:	River flood depth for a 1% annual exceedance probability (AEP) event for Tararu and Te Puru, derived from 2D local flood modelling. This modelling was done using a "stopbanks down" approach, i.e. the flooding that would occur if there were no stopbanks. In reality, most of Tararu and Te Puru are defended from a 1% AEP river flood event by the flood scheme in place. To determine the potential flood depth, the flood level data was reclassified into flood depth above ground level (from LiDAR data) in meters. Data is presented as integer raster files showing potential flood depth, and can be used for technical analysis. Raster VALUE field = depth m. Attribute information includes the year the modelling was completed (2013). Models have incorporated the best available information at the time of their creation, including LiDAR data, and flood event survey assessments.

Abstract:	Tsunami modelling for the eastern Coromandel and Firth of Thames by eCoast Limited which provides the tsunami depth data for a maximum credible event scenario. Contains depth values, thus to be used for technical purposes.
Statement:	Tsunami inundation depth for a maximum credible event scenario, derived from tsunami modelling for the eastern Coromandel (published between 2013 and 2017) and for the Firth of Thames (published 2019) by eCoast Limited. For the eastern Coromandel, this scenario is a near-source tsunami resulting from an earthquake at the Tonga-Kermadec Trench. For the Firth of Thames, this scenario is regarded as a local-source tsunami resulting from an earthquake on the off-shore section of the Kerepehi Fault. The modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. Data is presented as a raster file which provides tsunami inundation depth, and can be used for technical analysis. For the eastern Coromandel, the areas modelled include Whitianga, Mercury Bay, Cooks Beach, Hahei, Hot Water Beach, Kennedy Bay, Whangapoua, Matarangi, Kuaotunu, Opito Bay, Whangamata, Whiritoa, Pauanui and Tairua. For the Firth of Thames, the areas modelled include Colville, Coromandel, Manaia, Tapu, Te Puru, Thames, Miranda, and Whakatiwai. This dataset can be used to guide evacuation planning routes.

Abstract:	Polygon boundaries indicating the preliminary relative ground-shaking amplification rating of each polygon.
Statement:	The data was derived using manual digitising from published 1:250,000 geological maps with additional interpretation and synthesis. The data was derived using manual digitising from published 1:250,000 geological maps with additional interpretation and synthesis. The information presented in this layer and accompanying Client Report 33596B.10 (WRC Technical Document TR96/17 - Internal Document # 1719533) was developed by the Institute of Geological and Nuclear Sciences (now GNS) for Waikato Regional Council as a regional snapshot of Ground shaking susceptibility.
Other Information:	Data is presented as digital polygon boundaries which indicates the relative ground-shaking amplification rating of each polygon. Positional accuracy is Low; 80% well-known points located with +/- 250 m of actual position. The source maps were drafted in September 1996. The information was considered to be current at that time. Subsequent research is likely to have superceded this data. Research was undertaken up to 1996 by IGNS. Data aquisition from Manual digitising from published 1:250,000 geological maps with additional interpretation and synthesis. Reviewers at IGNS verified data after capture. This is the best available source information was used but data is generalised by virtue of its scale (1:250,000) and age (1960 up until 1993). Data should not be used at a scale beyond 1:250,000. Logical consistency is high. Data was supplied in both published (paper map) form, and as a digital GIS graphics file. Data was supplied in both published (paper map) form, and as a digital GIS graphics file. For related information: Institute of Geological & Nuclear Sciences Client Report 33596B.10 (available as WRC Technical Report # TR96/17)). WRC Policy Series 97/12 ‘Earthquake Risk Mitigation Plan’. Also see EW DOCS# 734315 and 1719533. Attribute accuracy is High. All polygons have a single attribute rating from A-D. Extract from Beanland, S., Drummond, G., Huber, P., Hull, A., and Townsend, T., 1996: Earthquake Hazard Analysis of Waikato Regional Council Area. Client Report 1996/3359B.10, Institute of Nuclear and Geological Sciences Limited, Lower Hutt. 4.1 Geological units and hazard zones Geological materials in the Environment Waikato Region have been classified and mapped into four units for this study. These units are used to define hazard zones. It is important to note that the data have been both compiled and digitised at 1:250,000 scale, unlike the active fault data which were compiled and digitised at 1:50,000 scale. The accuracy of the hazard zone boundaries is therefore much less than that of the fault locations. The four units, in order of decreasing hazards, are: UNIT A: Holocene (<10,000 yrs) fluvial, lake, fan and swamp deposits and near coastal estuarine and beach deposits. Commonly high in volcanic ash content. These deposits comprise unconsolidated, very soft to stiff intermixed peat, clay, silt, ash, sand and gravel. The groundwater table generally very high. May include liquefiable layers. Critical thickness of sediments 2-15m. MOST HAZARDOUS. Amplification of approximately two MMI units and/or settlement and liquefaction common. UNIT B: Quaternary (<2.5 Myr) fluvial and marine terrace deposits, lignite, dunes and, pumice alluvium and ignimbrite flows. Unsaturated, slightly weathered, unconsolidated gravel, ash and sand. QUITE HAZARDOUS. Amplification of approximately one MMI unit common. UNIT C: Tertiary (<75 Myr) sandstone, siltstone, mudstone, coal measures, limestone, and conglomerate. Includes volcanic rocks of various ages. Gravels dense to very dense. Rock strength weak to moderately strong. NOT VERY HAZARDOUS, except that fine grained rocks are particularly prone to slumping and land sliding, especially if saturated and/or denuded of vegetation cover. UNIT D: Basement rocks, (>75 Myr), greywacke (generally indurated, well bedded, sandstones and siltstones, moderately to highly deformed) and minor schist. Weak to very strong. LEAST HAZARDOUS.

Abstract:	ESTIMATED inundation area for the 1960 Chilean tsunami in Whitianga. This estimated inundation area is based on a combination of written and verbal eyewitness reports with survey and modelling information. The data is displayed as polygon and line vector data.
Statement:	This vector layer represents the estimated inundation area for the 1960 Chilean tsunami in Whitianga. The layer was produced as part of WRC Technical Report 2014/65, "Inundation of Whitianga town during the 1960 Chilean tsunami" (available on the WRC website). This report used a combination of both qualitative and quantitative approaches to determining inundation levels, including a review of existing historical written and verbal reports, on-site interviews with local eyewitnesses, a survey of a cliff-side marker of maximum inundation level and recent numerical modelling.
Other Information:	For more information on this data, please refer to WRC Technical Report 2014/65 - Inundation of Whitianga town during the 1960 Chilean tsunami

Abstract:	Areas in the Waikato District that are defended from river flooding by flood protection structures up to a specified design event.
Statement:	Defended areas are those that are defended from flooding by structural defences such as stopbanks or floodwalls. These areas are not defended from all flood events. They are defended from flooding from a specified water course up to a specified design flood event. The water course defended from and the design flood event (described by the event frequency as an AEP) are provided in the attribute information as ‘Water Course’ and ‘AEP’ respectively. The data is presented as vector polygon data and was created for use in the Waikato District Plan Review (2019). Although the defended areas are defended by most flood events (depending on their level of protection), they still have the potential to flood. Defended areas may flood due to a larger than design event, or due to failure of a structural defence. This risk that remains is known as "residual risk". The Waikato Regional Policy Statement and Practise note (https://discover.wairc.govt.nz/otcs/llisapi.dll?func=ll&objaction=overview&objid=12000091) includes policies and methods about residual risk, including that residual risk zones shall be identified in District Plans.
Other Information:	For the Waikato District, defended areas were determined using the following process: For all stopbanks or defended areas outside of the Huntly Urban area, the defended area was defined using existing Direct Benefit Rating layers (GIS_ALL.RACS_RATE_WAIKWAIP_DIR_BENEFIT; under “RACS – Rating Scheme – Waikato-Waipa – GIS Layer” in the Data Catalogue), and included an expert review to ensure correct benefit areas were used. For all stopbanks or defended areas within the Huntly Urban area, the defended area is defined as ground areas (based on 2007/2008 LiDAR) at or below the Design Flood Level of the relevant stopbank reach.

Abstract:	HAZARDS - Waikato River (Cambridge to Huntly) and Waipa River (Waipa Valley to Waikato River confluence) 1% AEP 2D flood extent as line geometry.
Statement:	2D flood extent as interpolated from a Mike 21 1D model on to a LiDAR derived topography using WaterRide Software. This information is created by inferring the 1% AEP 1D flood model (2009 TOPNET Design 1958 - 0.2) over the adjacent floodplain to create a 2D representation. There may be some inaccuracies and errors associated with this method. The modelling does not include the predicted effects of climate change on rainfall intensity and sea level rise. These maps do not show internal ponding in overbank areas which is likely in an event. Where stopbanks are overtopped, full flooding is shown. The model also only relates to the main channel, with many tributaries and some overbank areas not included. The presence of a hazard does not guarantee the existence of such a hazard, nor does the lack of information preclude the existence of a hazard or risk.

Hierarchy Level:	feature	Hierarchy Level Name:	Feature of HAZARDS - Regional Hazards Portal
Abstract:	Surveyed flood extent data that shows the inundation resulting from the Coromandel "Weather Bomb" event of June 2002. The resulting line data should be considered indicative and covers only parts of Sandy Bay, Port Charles, Colville, Koputauaki Bay, Coromandel Town, Manaia, Waikawau, Te Mata, Tapu, Waiomu, Te Puru and Tararu.
Statement:	The 2002 flood event is represented by line data from flood extent surveying which was done immediately following the flood event. Used for general viewing only, is imprecise data, not for use in any other capacity, i.e. not for planning zones, not for rating assessment, not for any other legal purpose. Data is too imprecise for any purpose other than “getting a general idea of the 2002 Flood extent”. Original request = S:\GISWork\GIS_Jobs\requests_08000_8500\8430_AdamMunro_CoroFloods features were stored in R:\AssetMan\GeoMedia_Warehouse\2002_flood_coromandel.mdb.
Other Information:	Data was digitized between 10th October 2002 and 25th October 2002. Taken from printed, then drawn on, and then scanned maps and heads up digitizing. Data was scanned from the printed aerial photo maps, registered as best possible, then digitized on screen and also digitized off original maps. The data is complete as per the printed copy. The data is digitized from registered scanned images. Spatially correct placement, although Spatial Xy varies due to inability to exactly match maps with existing data at such a large scale.

Abstract:	High level liquefaction assessment of the Waikato Region undertaken in general accordance with the guidance document ‘Assessment of Liquefaction-Induced Ground Damage to Inform Planning Processes’ published by the Ministry of Business, Innovation and Employment in 2017 https://www.building.govt.nz/building-code-compliance/b-stability/b1-structure/planning-engineering-liquefaction-land/
Statement:	To provide WRC with a region-wide liquefaction vulnerability assessment to identify areas of land susceptible to liquefaction as required in the RMA. The technical report and resulting map outputs will be used to inform planning and consenting processes. This work was supported by funding from the Waikato Regional Council. This assessment has been made at a broad scale across the entire region and is intended to approximately describe the typical range of liquefaction vulnerability across neighbourhood-sized areas. It is not intended to precisely describe liquefaction vulnerability at a property level. The Level A assessment is a desktop study that is mainly based on the geological map (QMAP, 3rd edition 2020). To assess the potential hazard of lateral spreading, a geomorphic mapping was carried out using the NZDEM North Island 25 metre Digital Elevation Model available from LINZ data service. The hydrology network and water bodies data came from LINZ data service as well. The seismic hazard model used for the assessment is based on the National Hazard Model (Stirling, 2012) and the NZTA Bridge Manual methodology (NZTA, 2018). No regional seismic hazard model has been developed for the assessment, which means that we did not take into account the potential spatial variability in seismic hazard across the region. The assessment does not include the geotechnical field investigations available on the NZ Geotechnical Database. However, the database has been consulted to check the properties of the ground and compare it with the geological information available. Depth to groundwater was based on data from the Waikato Regional Council groundwater monitoring network up to June 2021. The National Water Table (NWT) model developed by GNS Science (Westerhoff, 2018) was also used in areas not covered by the groundwater network. However, the NWT model was used with very low weight in the spatial analysis due to its uncertainty.

Abstract:	Local scale flood model coverage, indicating where local scale river flood modelling data are available. Flood level information is available for these rivers.
Statement:	Polygon data created with the purpose to indicate to users of the Waikato Regional Hazards Portal where detailed flood modelling is available (when map is zoomed out/before local scale flood modelling is visible), and where the model boundaries are (for Thames Coromandel and Taupo Districts only). For the Waikato and Waipa Rivers, the data shows a less detailed version of the modelled 1% AEP flood extent (effectively a simplified 100m buffer applied around the modelled flood extent geometry). For the Thames Coromandel and Taupo Districts, the data shows the model boundaries, as rectangle polygon data.

Abstract:	Modelled water depths for the hypothetical situation of probable maximum flood, resulting from a Karapiro dam break (assumes instantaneous, total removal of the dam, which is an extreme scenario).
Statement:	This data is presented as raster data which shows the modelled water depths for the hypothetical scenario of a Karapiro dam break flood (rainy day scenario/probable maximum flood). This data was produced as part of a report commissioned by Mercury Energy (then Mighty River Power) in 2012 from an external expert (DHI Water and Environmental Limited). This is part of ongoing prudent emergency response preparedness, with at least seven related and detailed studies undertaken since 1989. The report models water movement in the hypothetical situation of a dam break, and assumes an instantaneous, total removal of the dam, which is an extreme scenario. Although the underlying assumption of this report is of sudden complete removal of the dam, it does not imply that the dam is unsafe in any way. For the modelling, a hybrid one- and two-dimensional modelling approach was chosen. The two-dimensional method was used where over-bank flow is likely, and the one-dimensional method was used where the flood wave is expected to be confined within the channel. Mercury Energy should be contacted for any further information, including to request the modelling report.

Abstract:	River flood depth for the 1% annual exceedance probability (AEP) event for a number of rivers and streams, derived from local flood modelling. Does not contain depth values, only depth classes, thus is to be used for mapping purposes.
Statement:	River flood depth for a 1% annual exceedance probability (AEP) event, derived from 2D local flood modelling. To determine the potential flood depth, the flood level data was reclassified into flood depth above ground level (from LiDAR data) in meters. Data is presented as polygons which show flood depth classes (not values), and should be used for mapping purposes. Attribute information includes the year the modelling was completed (from ~2006 onwards). Models have incorporated the best available information at the time of their creation, generally including (but not always) LiDAR data, and flood event survey assessments. A climate change component is generally included in the modelling and will likely be based on the best available MfE guidance from the period of modelling. All flood depth information takes into account the presence of WRC-managed stopbanks and floodwalls, with the exception of Tararu and Te Puru (which have been modelled using a “stopbanks down” approach). The LiDAR data is converted to a grid which has limitation when assessing small stream channels and topographic features such as ridges. This may lead to minor discrepancies in water flows which may lead to limitations in defining flood extents. Internal drainage such as storm water systems, culverts, piping etc, are generally not included in the modelling. Depending on how the model is configured, they often only consider the main watercourse, so flooding of minor channels, tributaries, ponding and coastal inundation may not be represented by the flood extent. This information is not intended to replace more detailed hydrogeological and survey data required for Building Consents or Resource Consents. The information shown is current as of the time of modelling, including assumptions around climate change and hydrology etc. Note that this is a “live” dataset and further additions will be made as and when available and verified.
Other Information:	For further information, including the model limitations for a particular area, please contact the Regional Resilience Team.

Abstract:	River flood hazard classification for a number of rivers and streams, derived from local flood modelling. REPLACES the obsolete feature HAZ_FLOOD_HAZ_MOD_THAMES_CORO.
Statement:	River flood hazard classification for a 1% annual exceedance probability (AEP) event, derived from the (2D) modelled flood depth and flood speed data for a number of rivers and streams. To determine the potential flood hazard classification a matrix was designed combining both flood depth and flood speed. The hazard classification has been divided into three levels of river flood hazard based on the likely impact on people, property and surrounding environment. These are: 1. Low- The combined depth and speed of floodwaters are unlikely to impair the maneuverability or stability of the average person and damage to property is likely to be non- structural and mainly due to inundation and deposition of sediment. 2. Medium- The combined depth and speed of floodwaters are likely to start to impede the maneuverability or stability of the average person and damage to property is unlikely to be structural provided that weak points such as windows and doors are retained above flood level. 3. High- The combined depth and speed of floodwaters are likely to significantly impede the maneuverability or stability of the average person and damage to property is likely to be widespread and structural, including instances where building have been raised above the flood level. In addition, there is also Defended which covers areas defended from river flood hazards (by stopbanks or other protection measures). Data is presented as polygons showing potential flood hazard. Attribute information includes the year the modelling was completed (from 2006 onwards). Models have incorporated the best available information at the time of their creation, generally including (but not always) LiDAR data, and flood event survey assessments. A climate change component is generally included in the modelling and will likely be based on the best available MfE guidance from the period of modelling. Note that for Grahams Creek a climate change component is not included for the flood hazard classification, due to the design of the flood scheme to current climate only as a result of community consultation. The LiDAR data is converted to a grid which has limitation when assessing small stream channels and topographic features such as ridges. This may lead to minor discrepancies in water flows which may lead to limitations in defining flood extents. Internal drainage such as storm water systems, culverts, piping etc, are generally not included in the modelling. Depending on how the model is configured, they often only consider the main watercourse, so flooding of minor channels, tributaries, ponding and coastal inundation may not be represented by the flood extent. This information is not intended to replace more detailed hydrogeological and survey data required for Building Consents or Resource Consents.

Abstract:	Tsunami modelling for the eastern Coromandel and Firth of Thames by eCoast Limited which shows tsunami depth for a maximum credible event scenario. Does not contain depth values, only depth classes, thus is to be used for mapping purposes.
Statement:	Tsunami inundation depth for a maximum credible event scenario, derived from tsunami modelling for the eastern Coromandel (published between 2013 and 2017) and for the Firth of Thames (published 2019) by eCoast Limited. For the eastern Coromandel, this scenario is a near-source tsunami resulting from an earthquake at the Tonga-Kermadec Trench. For the Firth of Thames, this scenario is regarded as a local-source tsunami resulting from an earthquake on the off-shore section of the Kerepehi Fault. The modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. Data is presented as polygons which show tsunami inundation depth classes (not values), and should be used for mapping purposes. For the eastern Coromandel, the areas modelled include Whitianga, Mercury Bay, Cooks Beach, Hahei, Hot Water Beach, Kennedy Bay, Whangapoua, Matarangi, Kuaotunu, Opito Bay, Whangamata, Whiritoa, Pauanui and Tairua. For the Firth of Thames, the areas modelled include Colville, Coromandel, Manaia, Tapu, Te Puru, Thames, Miranda, and Whakatiwai. This dataset can be used to guide evacuation planning routes.

Abstract:	Modelled Tsunami Hazard for a Maximum Credible Event for populated parts of Coromandel Peninsula, Firth of Thames, Kawhia Harbour, Marokopa, Awakino and Mokau.
Statement:	Tsunami hazard for a maximum credible event scenario, derived from tsunami modelling for populated parts of the Coromandel Peninsula (published between 2013 and 2017) and for the Firth of Thames (published 2019) and for Opoutere, Wharekawa Harbour, Kawhia Harbour, Marokopa (published 2022) derived from eCoast Limited modelled tsunami flood depth and speed grid data. This data illustrates the expected tsunami hazard for a modelled Maximum Credible Event scenario. For the eastern Coromandel, this scenario is a near-source tsunami resulting from an earthquake at the Tonga-Kermadec Trench. For the Firth of Thames, this scenario is regarded as a local-source tsunami resulting from an earthquake on the off-shore section of the Kerepehi Fault. For the West Coast models this is the worst case scenario selected from a variety of model scenarios and tsunami sources. The modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. Data is presented as polygons which show tsunami hazard, classified as low, medium or high hazard. The hazard classification is the same used for flood hazards. This tsunami hazard data was derived from combining tsunami depth and tsunami speed data. For the eastern Coromandel, the areas modelled include Whitianga, Mercury Bay, Cooks Beach, Hahei, Hot Water Beach, Kennedy Bay, Whangapoua, Matarangi, Kuaotunu, Opito Bay, Whangamata, Whiritoa, Pauanui and Tairua. For the Firth of Thames, the areas modelled include Colville, Coromandel, Manaia, Tapu, Te Puru, Thames, Miranda, and Whakatiwai. On the West Coast the areas modelled included Kawhia Harbour, Marokopa, Awakino and Mokau coast.

Abstract:	Inundation extent polygons that have been mapped along the Kaiaua Miranda coastline, based on a desktop study of pasture burn captured in aerial imagery (early 2018) following the 4-6 January 2018 storm surge event.
Statement:	This data is presented as vector polygon data which shows the inundation extent along the Kaiaua Miranda coastline from the 4-6 January 2018 storm surge event, as represented by pasture burn (dead pasture due to salt water inundation). The polygons were mapped based on pasture burn shown on aerial imagery that was captured soon after the event, in early 2018. The digitisation of the pasture burn was completed by the Waikato Regional Council (WRC) Regional Hazards Team. Where the pasture burn lines were unclear, LiDAR (elevation) data and the surveyed inundation data was used to assist with mapping. The inundation extent has often not been mapped in built up areas due to the difficulty of identifying pasture burn in these areas. The lack of a desktop inundation extent polygon covering an area does not necessarily mean that inundation did not occur in this area. The presence of a desktop inundation extent polygon does not necessarily mean that inundation did occur in this area.

Abstract:	Surveyed points that show the inundation extent for the 4-6 January 2018 storm surge event at locations along the Firth of Thames and Coromandel Peninsula.
Statement:	This data is presented as vector point data which shows the surveyed inundation extent for the 4-6 January 2018 storm surge event. Attribute information includes the elevation of the ground level at each survey point (in various datums) – these elevations do not necessarily represent the maximum level that the water reached, although they may provide an indication. Post event data collection was undertaken by a variety of field teams and then collated into a mapped area by Waikato Regional Council (WRC). These were collected by the WRC Environmental Monitoring (EM) team, who visited some rural sites and mapped burnt pasture lines. The WRC EM team also visited sites along the western Coromandel Coast mapping inundation extent points in townships where possible from Port Charles to Tararu. This was combined with some anecdotal water level reports collected by Thames Coromandel District Council during their post-event inspections. This data shows the significant amount of damaging inundation along the Thames Coast Road, as well as substantial impacts to residential (particularly at Waiomu, Te Puru and Kaiaua), and rural (Kaiaua/Miranda Coast) areas. Land elevations that the inundation affected varied across the area dependent on local topography and hydrodynamic effects. Surveyed debris/burnt pasture lines caused by inundation from the event varied in average elevation from RL 1.2 m on the southern Kaiaua/Miranda Coast to 3.0m across the Hauraki Plains. The maximum elevation of the surveyed inundation lines was at 5.7 m (TVD) at Ngarimu and Whakatete Bay, if accurately identified this is likely due to wave effects.

Abstract:	The Regional Scale Flood Hazard data is polygon features of areas in the Waikato Region that may be susceptible to flooding, based on varying sources of information. Intended to be used to indicate where further flood hazard investigation may be required.
Statement:	The data is a compilation of flood hazard information which is sourced from a combination of; previous event information (photos and aerial imagery, anecdotal information, post-event surveys), flood modelling, flood protection and drainage scheme information, and elevation data. Data is presented as polygons which represent susceptibility to flooding, with attribute information indicating type of flooding, historical floods, data reference and quality, etc. The data attribute also includes "FLOOD_HAZARD_ID", which is an ID number that corresponds to text files with additional information, available internally in Discover folder # 30 07 10. This data should be viewed in conjunction with flood protection and land drainage asset data (datasets with the prefix RACS, many of these layers are publically available from the CoLAB- Waikato Data Portal). This is for general public information on susceptibility to flooding in the Waikato Region, and should be used to indicate where further investigation may be required. It is important to note that this information is not suitable to use for building or resource consent applications as it is not suitable to be viewed at a property scale.
Other Information:	Regarding data accuracy, the least accurate data is from polygons plotted on 1:50,000 topo map then transferred to this dataset. The most accurate data is derived from flood modelling. Information on data accuracy can be seen in the attributes. Due to the low accuracy of much of the data, it should not be viewed beyond a 1:50,000 scale, and ideally not using aerial photography as the base layer. Collation of data has occurred from November 1996 to April 2019. The information shown is current as of 1 April 2019. Note that this is a “live” data set and further additions will be made as and when available and verified. The latest updates went live in July 2019. Refer to WRC DOCS# 951493 and 971022 for data quality. Note that the verification process used has determined the level of accuracy. Data were collected by multiple people over time and originally collated in Excel spreadsheets. These were output to MS Access to create the draft GIS layer and edited for consistency of format and style together with removal of obvious typographic errors and such like. Logical checks were carried out to ensure that valid attribute values are used where possible – such as valid territorial authority names, and document references. Basic QA in the GIS included topological verification (all polygons close etc.) and that required attribute fields are populated. Spatial and aspatial data were finally loaded into the WRC Corporate Spatial Database to form the corporate GIS layer. Data form is in GIS Layers and MS Word Documents. The data is stored in Waikato Regional Council's corporate spatial database as Features that can be loaded using WRC’s GIS, and can be accessed by SQL-based application. This dataset was previously named RACS_FLOOD_HAZARD.

Abstract:	Simplified tsunami inundation zones (formerly known as 'Blue is wet') derived from maximum credible event tsunami modelling for populated parts of Coromandel Peninsula, Firth of Thames, Kawhia Harbour, Marokopa, Awakino and Mokau. Plus, Preliminary - Susceptible Area modelling for other populated parts of the West Coast.
Statement:	Tsunami inundation zones (formerly known as 'Blue is wet'), are those that may be affected by tsunami in a maximum credible tsunami event, i.e. they represent the expected worst-case tsunami inundation. These areas represent areas that should be evacuated from in the event of a “long or strong” earthquake, or a tsunami warning. The tsunami inundation zones were derived differently for the different coastal areas in the Waikato. For the Coromandel Peninsula, the Firth of Thames and Kawhia Harbour, Marokopa, Awakino and Mokau, the inundation zones are a simplified version of the modelled extent for a maximum credible tsunami event – wave heights vary and there is unlikely to be time for an official tsunami warning. For the remaining populated locations of the West Coast (Port Waikato, Raglan Harbour, Aotea Harbour, Taharoa, Kiritehere and North of Marokopa, Waikawau and North of Awakino, the inundation zones are areas likely to be susceptible to tsunami, based on preliminary modelling and investigation – wave heights are likely to be relatively small, and there will likely be time for an official tsunami warning. For more information on tsunami evacuation, including Community Response Plans, the Emergency Management staff for the relevant District Council should be contacted. More information on tsunami hazard can be found on the Waikato Regional Council tsunami webpages.
Other Information:	Feature attributes include MODEL_TYPE, MODEL_AREA and REGION. A view name change from HAZ_TSUNAMI_BLUE_IS_WET to HAZ_TSUNAMI_INUNDATION_ZONES was done 29th June 2021 under REQ175278 Under REQ188903 Port Charles, Opoutere, Wharekawa Harbour, Kawhia Harbour, Marokopa, Awakino and Mokau were new models added in 2022. The opportunity was taken at this time to improve the data set by: 1.) Clipping the tsunami inundation zones to a 200m buffer of the coastline. 2.) Extending the tsunami inundation zones up the parts of harbours and estuaries that were outside the modelled area by following the LINZ mean high water coastline. 3.) Extending some tsunami inundation zones landward where the inundation would clearly continue beyond the modelled area, using LiDAR contours to estimate the additional extent. These and other minor edits are described in detail in WRC doc# 24807740

Abstract:	Model boundaries for Maximum Credible Event tsunami modelling for Coromandel Peninsula, Firth of Thames, Kawhia Harbour, Marokopa and Awakino-Mokau and preliminary modelling for other populated locations along the West Coast of the Waikato Region.
Statement:	Model boundaries for the maximum credible event tsunami modelling carried out for the Coromandel (published between 2013 and 2017), Firth of Thames (published 2019) and Opoutere, Kawhia Harbour, Marokopa, Awakino and Mokau (published 2022), by eCoast limited. Preliminary modelling (to show tsunami susceptible areas) carried out for other populated parts of the West Coast (published 2015), by eCoast limited. The model boundaries show which areas were included in the modelling. Areas that are outside of the tsunami model boundaries have not been modelled but may still be at risk of tsunami inundation. For the Coromandel, Firth of Thames, Kawhia Harbour, Marokopa, Awakino and Mokau the modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. For the remaining parts of the West Coast, only preliminary modelling and investigation has been undertaken (as the preliminary results showed that wave heights are likely to be relatively small, and there will likely be time for an official tsunami warning). For more information on tsunami evacuation, including Community Response Plans, the Emergency Management staff for the relevant District Council should be contacted.
Other Information:	More detailed information on the numerical modelling carried out by eCoast Limited can be found on the Waikato Regional Council tsunami webpages. WRC Spatial Information carried out GIS work in 2022 and 2023 to create the bounding boxes representing the model boundaries for five new models for Port Charles, Opoutere and Wharekawa Harbour, Kawhia Harbour, Marokopa, and Mokau/Awakino. This work also involved splitting out the new model areas from existing preliminary model areas where they overlapped for Kawhia Harbour, Marokopa, and Mokau/Awakino.

Abstract:	“Safe zones” are areas that should be evacuated to (if possible) in the event of a tsunami. They are areas above the 20m contour, which adds an additional factor of safety on to the Tsunami “Inundation Zones” that are at greater risk of being inundated.
Statement:	“Safe zones” are areas that should be evacuated to in the event of a tsunami, if it is possible to do so. Note that for most of the Waikato coastline, in local (NZ) or regional (SW Pacific) sourced tsunami causing events, there is unlikely to be time for an official tsunami warning, thus follow the “Long or Strong: Get Gone” message. The Safe Zones are defined as areas in the vicinity of the coast which are above the 20m contour line. The 20m contour line is used, as for the eastern Coromandel (highest tsunami hazard in the Waikato region), this elevation is not predicted to be affected by a maximum credible tsunami event in any coastal communities. The 20 m contour is used for the rest of the Waikato Region for consistency and to be conservative (although tsunami wave heights are predicted to be lower for the Western Coromandel, Firth of Thames and West Coast – as shown by the “Tsunami inundation zones". Note that due to the low-lying nature of the Hauraki Plains, no “Safe zone” exists for this area inland. The messaging is instead to move as far away as possible from the coast and any rivers connected to the coast. For more information on tsunami evacuation, including Community Response Plans, the Emergency Management staff for the relevant District Council should be contacted. More information on tsunami hazard can be found on the Waikato Regional Council tsunami webpages.
