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 twelve 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 Ministry of Civil Defence and Emergency Management.

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 has been developed for each dataset.
