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.

Toitū Te Whenua is working with the owners of these datasets to ensure the data is accessible and available to support emergency management and an improvement plan for 2021/22 has been developed for each dataset:
