Description: Updated in October 2023. The layer replaces previous tsunami evacuation zones with a single tsunami evacuation zone (blue zone). The blue zone marks the zone that people should evacuate from in a long or strong earthquake or when a tsunami warning is in place in the Bay of Plenty. The single (blue) zone replaces the previous three coloured zones (red, orange and yellow) to make it simpler for people to understand the evacuation zones (and maps).The new tsunami evacuation zone has been updated to align with LINZ High Water Spring, current aerial imagery and recent additional tsunami modelling undertaken for different sections of the coastline.The blue zone adjacent to the coastline within the Tauranga City Council boundary have been informed by modelling conducted by Tonkin + Taylor in 2013 and 2020. The remainder of the blue zone across the Bay of Plenty coastline has been informed by modelling conducted by GNS Science, eCoast and previous evacuation zones (based on the furthest inland extent).

Name: Tsunami Inundation Max Depth - 2m wave (above MHWS)
Display Field: Zone
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: This vector dataset comprises the extent of the tsunami inundation mapping for the 2m wave height scenario. It is derived by BOPRC from the original raster dataset of the same scenario provided by GNS Science in 2024 for the Bay of Plenty Region. The dataset is in the NZTM2000 projection.

Description: This vector dataset comprises the extent of the tsunami inundation mapping for the 2,500 year average recurrence interval scenario. It is derived by BOPRC from the original raster dataset of the same scenario provided by GNS Science in 2024 for the Bay of Plenty Region. The dataset is in the NZTM2000 projection.

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.
