  • Brief hazard description with a link to Civil Defence and Emergency Management (CDEM) for key messages on preparedness what to do in an event.

  • Interactive maps displaying natural hazard layers (GIS) made available by the District and City Councils across the region.  Type in your address and get to know your hazards.

  • Technical documents are provided under the resources tab for further information if you want to dig deeper.


The natural hazard layers are based on existing research.  Not all areas of the region have been investigated.  Therefore, natural hazards may exist in areas not currently mapped in BayHazards.

The precision and accuracy of the data varies. It is important that you obtain expert advice to help to interpret the information for risk assessment purposes. This data is not a Land Information Memorandum (LIM).

Work in progress

BayHazards has been developed in collaboration with the Bay of Plenty Natural Hazards Forum. We are currently working on uploading the following additional natural hazards to BayHazards this year:

  • Liquefaction
  • Tsunami wave run-up
  • Landslides
  • Sea level rise
  • River flooding

All new natural hazard GIS data will also be available on the Bay of Plenty Open Data Portal.
