New Zealand FloodScore™
Quickly evaluate and quantify flood risk to any property in New Zealand
New Zealand FloodScore™ provides property-level flood risk scores and flood risk information for over 50% of properties in New Zealand. You can use it to quickly evaluate and quantify flood risk. It’s available as a full or partial database, or as spatial layers.

New Zealand FloodScore provides property-level flood risk data for over half of New Zealand. It has been designed to support insurers and brokers in making quicker, more accurate decisions around flood risk.
The data is derived using the same advanced modelling techniques that are used by major insurers internationally and integrates the most complete and up-to-date flood and building stock data available.
New Zealand FloodScore uses the advanced flood modelling techniques developed for New Zealand FloodMap™. It incorporates the most current hydrology data from LINZ, and extensive LiDAR coverage including the entire LINZ LiDAR database.
This data is used to formulate a risk index, which reflects the average annual loss (AAL) for a property. This ‘flood score’ takes into account the likelihood of an individual property being flooded due to rainfall, overflowing rivers or tidal surges, as well as the damageability for different property classes. To improve the stability and accuracy of the flood scores, they’re derived from a range of return periods (1 in 20, 75, 100, 250, 500, 1000 and 10,000 year scenarios), along with complex risk-scoring algorithms.
