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).

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.

Description: Layer last updated: 04/10/2021There is also a hosted version for online applications.Report Reference - A3787391LIQUEFACTION ASSESSMENT SUMMARYThis liquefaction assessment has been undertaken in general accordance with the guidance document ‘Assessment of Liquefaction-induced Ground Damage to Inform Planning Processes’ published by the Ministry for the Environment and the Ministry of Business, Innovation and Employment in 2017.https://www.building.govt.nz/building-code-compliance/b-stability/b1-structure/planning-engineeringliquefaction-land/Client Bay of Plenty Regional Council (BOPRC)Assessment undertaken byTonkin & Taylor Ltd, PO Box 317, Tauranga 3140Extent of the Study Area The Study Area aligns with the Bay of Plenty Regional Council boundaryexcluding the Tauranga City Council territory. The Study Area also includes two areas outside of the regional boundary, that being a small area to the west of Mamaku and a large area south of Lake Rotorua to incorporate all of the Rotorua Lakes Council Territory.Intended RMA planning and consenting purposesTo provide BOPRC with a region-wide liquefaction vulnerability assessment toidentify areas of land susceptible to liquefaction as required in the Regional Policy Statement (RPS). The technical report and resulting map outputs will be used to inform land use, subdivision and building consent applications. In particular the vulnerability assessment outputs will be utilised by stake holders to inform the risk assessment requirements for liquefaction prone land. Other intended purposes Not applicableLevel of detail Level A (basic desktop assessment)Notes regarding base informationThe available base information provides enough information for a Level A (basic desktop assessment) level of detail across the Study Area. The main factor controlling this level of detail is the spatial extent of the available geotechnical investigations and groundwater information across the Study Area. There are some small areas (e.g. parts of Whakatāne and Rotorua) where higher levels of detail could be supported by the available base information. Undertaking these studies at a higher level of detail is outside of the scope of work for this project. Other notes 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 individual property scale. This information is general in nature, and more detailed site-specific liquefaction assessment may be required for some purposes (e.g. for design of building foundations).A key consideration of the liquefaction vulnerability categorisation undertaken in accordance with the MBIE/MfE Guidelines (2017) is the degree of uncertainty in the assessment. Discussion about the key uncertainties in this assessment is provided in sections 3.3 and 3.4 of this report.
