Major changes have come to New Zealand property information. As of October 17, 2025, all Land Information Memorandum (LIM) reports now include standardized flood risk ratings in a clear, comparable format. This affects every property owner in New Zealand.
What Changed in October 2025?
New government regulations require councils to include natural hazard information—including flood risk—in LIM reports using a standardized format. This means homeowners, buyers, and sellers will see clear flood risk ratings that can be easily compared across properties and regions.
Key Facts:
- 219,000 homes in New Zealand are in designated flood zones
- $180 billion worth of properties potentially affected
- October 17, 2025 - Standardized ratings became mandatory on all LIMs
- Property values - Flood ratings now appear on official LIM reports, potentially affecting valuations
Why This Matters for NZ Homeowners
Unlike current council flood viewers that vary by region, the new system creates a consistent way to understand and compare flood risk across the country. This transparency helps:
- Home buyers - Make informed decisions before purchase
- Current owners - Understand their property's risk profile
- Insurance seekers - Anticipate coverage implications
- Property sellers - Prepare for disclosure requirements
What to Do Next
Understanding your property's flood risk under the new regulations is crucial. Here's how to get started:
- Check your local council's flood viewer - Most councils have online tools showing flood zones (see our regional guide)
- Request a current LIM report - See what information already exists for your property
- Understand flood categories - Learn what different risk levels mean (complete guide)
- Explore mitigation options - If your property is at risk, find out what you can do
Flood Risk and Property Values
The standardized flood risk information on LIM reports may impact property values. Research shows that properties with disclosed flood risk can see valuation changes, particularly in high-risk areas. Learn more about protecting your property value.
