NZ FloodMap & FloodScore

Get a comprehensive view of flood risk throughout New Zealand

With flood risk increasing with climate change, the need for accurate, consistent flood risk modelling has never been more important.

NZ FloodMap is a comprehensive flood risk assessment dataset which helps with the visualisation of potential flood impact. It's complemented by NZ FloodScore, which offers a simple score system that enables easy flood risk assessments.

Modelling covers 100% of NZ, with 70% of properties at 5m urban resolution, modelled using LiDAR when available, and 8m grid resolution in rural regions .

Helps with understanding flood risk from all the major types of flooding, which can be viewed individually or in combination over different return periods.

Flood defences are incorporated for over 35,000 properties, designed to provide a more holistic view of risk for properties in New Zealand.

Have the ability to use NZ FloodMap in conjunction with other datasets, including your own, or with CoreLogic BaseMaps  to help visualise real world impact.

Explore a sample of NZ FloodMap data through the interactive NZ MasterMap portal and experience for yourself how it can support smart decision-making
