Twelve priority data sets have been identified as playing a critical role in decision-making in the four stages of emergency management: risk reduction, readiness, response and recovery, and climate change.

The 12 datasets which cover people, property, transport, rivers and land were identified by LINZ working with NZGIS4EM (New Zealand GIS for Emergency Management), and representatives from central and local government agencies including the National Emergency Management Agency in 2019.

The Local Government Geospatial Alliance (LGGA) reviewed the priority data improvements for 2020/21.

LINZ is working with the owners of these datasets to ensure the data is accessible and available to support emergency management and an improvement plan (PDF, 661KB) has been developed for each dataset.

Read the key datasets for resilience and climate change overview for a summary of each of the datasets, including the authoritative source and lead agency responsible for maintaining the data. Discover the data improvements implemented to date, and what our customers in the emergency management community have identified as their highest priorities for future improvements.
