Get the most complete picture of flood risk throughout New Zealand

NZ FloodMap - now with more coverage and greater detail

Floods are New Zealand's most frequently occurring natural hazard. Compatible with most GIS systems, including CoreLogic’s BaseMaps, NZ FloodMapTM is designed to provide a consistent spatial view of flood risk throughout New Zealand, for both large areas and individual properties.

Our recent data update means that NZ FloodMap now offers:

  • 100% coverage - with over 100k additional properties included
  • 70% of properties at 5m urban resolution 
  • Flood Defence data for over 35k properties

Complete visibility

NZ FloodMap's modelling covers over 99% of New Zealand, making it a truly comprehensive tool for evaluating flood risk. Providing granular detail of flood risk throughout the country, it can be ideal for use across any sector that has a need to better understand flood risk, from banking and insurance, to local and central government, and more.

Get all the detail you need

The tool offers a high level of detail, with a view down to 5m resolution, modelled using LiDAR when available in urban areas and 8m grid resolution in rural regions. It provides insights into flood risk from all the major types of flooding – fluvial (riverine), pluvial (surface water/flash) and tidal (coastal/estuarine) – and provides a range of return periods, from 1 in 20 year severity through to worst case 1 in 10,000 year.

Work flexibly

NZ FloodMap is compatible with most GIS tools and underwriting platforms, and can be easily integrated with most existing systems. You have the option to use it in conjunction with other datasets, including your own, or with CoreLogic BaseMaps to visualise real world impact. It is also the perfect complement to NZ FloodScore – another comprehensive flood risk solution that is built with the same data and allocates an easy-to-understand risk 'score' to properties.

Customise it to your needs

The flexibility and level of detail NZ FloodMap offers can make it ideal for a wide variety of commercial and other purposes. It can be used by insurers in assessing concentration risk in a portfolio, determining pricing for policies for affected properties, or setting appropriate exclusions or excess amounts. Banks may use NZ FloodMap to help mitigate against exposure across a property portfolio, or to follow compliance processes relating to lending. It can also be used by commercial utilities companies to assess the impact of floods on services. And it can be used by government bodies to plan future infrastructure, prepare emergency responses, and so much more.
