From 11 November 2026, Westpac NZ is introducing Natural Hazard Risk Insights into its residential lending process for new lending applications involving a new residential property.
This means Westpac will now consider property-specific natural hazard information as part of its overall lending assessment, including:
🌊 Flooding Risk – Potential exposure to flooding.
🏖️ Coastal Risk – Potential coastal hazards affecting the property's location.
⛰️ Landslide Risk – Potential land instability and landslide exposure.
📍 Surrounding Area Risk – Combined natural hazard exposure in the property's surrounding area.
What does this mean for property buyers?
Under the new process:
1️⃣ A Natural Hazard Risk Insights Report will be generated for each property submitted to Westpac, where applicable. Advisers will be expected to share this report with customers before they make property decisions.
2️⃣ Higher natural hazard risk does NOT automatically mean a mortgage decline. Westpac has confirmed that natural hazard information is only one of several factors considered in its overall lending assessment. Some properties may require additional specialist review before a lending decision is confirmed.
3️⃣ More property due diligence may be required. Buyers should consider reviewing:
- Council hazard maps and LIM reports.
- Insurance availability and terms.
- Registered property valuations.
- Geotechnical or engineering reports, where appropriate.
Which applications are affected?
✔️ New residential property purchases – Yes.
✔️ Refinancing with a new residential security – Yes.
❌ Top-ups on existing securities – Not currently included.
❌ Applications already in progress before 11 November 2026 – No change.
Our thoughts at BSI Brokers
Property ownership is a long-term financial commitment. While location, price and potential capital growth are important considerations, understanding the risks associated with a property's location is equally important.
A property that appears affordable today may carry additional considerations in the future, particularly when it comes to lending, insurance availability and long-term ownership.
Our advice is simple: Don't just look at the property. Understand the risks that come with it.
If you are planning to purchase a home, invest in property or refinance, speak with your mortgage adviser early so you can better understand the lending requirements and prepare accordingly.
