Welcome to NZ Flood Risk

NZ Flood Risk is a comprehensive resource designed to help New Zealand homeowners, buyers, and property professionals understand and navigate the new standardized flood risk rating system now in effect for all LIM (Land Information Memorandum) reports.

What We Do

On October 17, 2025, significant changes came into effect for how flood risk information is reported in New Zealand. All councils are now required to include standardized flood risk ratings on LIM reports, affecting over 219,000 homes across the country worth an estimated $180 billion.

We provide clear, accessible information to help you:

• Understand the new regulations – What's changing, when it's happening, and why it matters
• Interpret flood risk ratings – Learn what Categories 1, 2, and 3 mean for your property
• Access regional resources – Find your council's flood viewers and LIM request processes
• Protect your investment – Discover how flood ratings affect property values and insurance
• Take informed action – Explore mitigation options and understand your rights

Why This Matters

Flood risk information has historically been fragmented across different councils, making it difficult for homeowners to understand their exposure. The new standardized system brings transparency and consistency, but it also means property owners need reliable information to make informed decisions.

Whether you're buying a home, selling a property, or simply want to understand your current flood risk, NZ Flood Risk is here to provide the guidance you need.

Our Mission

We believe every New Zealander deserves access to clear, accurate information about flood risk. Our goal is to demystify the regulatory changes, provide practical resources, and help you make confident decisions about your property.

This site is independently maintained and regularly updated to reflect the latest information from councils, government agencies, and industry experts.
