Description: This vector dataset comprises the extent of the Red tsunami evacuation zone. It is developed by tracing all areas with elevation less than 2 m above high-tide (MHWS) that are connected to the sea, but is limited to the extent of the Orange Zone. The dataset is in the NZTM2000 projection. For more details see Roger JHM, Gusman AR, Hughes L, Wang X, Lukovic B, Power W, Mueller C, Burbidge D 2024.

Description: This vector dataset comprises the extent of the Orange tsunami evacuation zone. It is derived from the OrangeZone_MaxH raster dataset and outlines the modelled inundated area. The dataset is in the NZTM2000 projection. For more details see Roger JHM, Gusman AR, Hughes L, Wang X, Lukovic B, Power W, Mueller C, Burbidge D 2024.

Name: Tsunami Inundation - Yellow Zone Extent 2025
Display Field: Zone
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: This vector dataset comprises the extent of the Yellow tsunami evacuation zone (Blue Zone in Bay of Plenty). It is derived from the YellowZone_MaxH raster dataset and outlines the modelled inundated area. The dataset is in the NZTM2000 projection. For more details see Roger JHM, Gusman AR, Hughes L, Wang X, Lukovic B, Power W, Mueller C, Burbidge D 2024.

Description: This vector dataset comprises the land and sea areas separated along the coastline at zero elevation in terms of MVD-53. It complements the tsunami raster outputs to differentiate areas where the raster values represent tsunami flow depth (land) from the areas with values representing tsunami wave elevation (sea). The dataset is in the NZTM2000 projection. For more details see Roger JHM, Gusman AR, Hughes L, Wang X, Lukovic B, Power W, Mueller C, Burbidge D 2024.

Description: Torrential rain hit the Bay of Plenty, specifically the Rangitaiki, Whakatane and Waimana Catchments from 15 July to 18 July 2004 when a trough of low pressure stalled directly over the Rangitaiki Plains. Extensive flooding from river and surface ponding resulted. A stopbank breach on the East bank above the town of Edgecumbe exacerbated the situation. Part of Whakatane town also flooded due to the heavy rain. A civil defence emergency resulted, with about 1000 evacuees, huge stock movements and major loss of propertyIt is envisaged that any mapping of future flood event extents would be added to this dataset.
Description: This dataset is the faults data for New Zealand. The dataset is a product of the QMAP Geological Map of New Zealand Project and was produced by GNS Science. It represents the most current mapping of faults for New Zealand in a single dataset at a scale of 1:250 000. The dataset is stored in an ESRI vector geodatabase and exported to Geoserver. The dataset comprises arcs with each arc having attributes describing the type of fault, its name, age and activity, and the sense of movement and cumulative slip.
