Will NZ mortgage rates drop in 2026?

Yes, with the OCR currently at 3.25% and further RBNZ cuts forecast for late 2026, retail interest rates are expected to fall. Fixed 1-year terms are sitting around 5.85% special rates, with wholesale swap rates trending down.

Should I fix for 1 year or 2 years in NZ today?

Most NZ borrowers are choosing 1-year fixed terms to avoid locking in for too long while rates are falling. This gives the flexibility to refix at a lower rate in 12 months, though 2-year rates offer slightly lower pricing today.

What is the current stress-test rate for NZ banks?

As of June 2026, major NZ banks are testing servicing capacity at a stress rate around 7.45%, down from peak levels of nearly 9.0%. A lower test rate expands your maximum borrowing power significantly.

How does the OCR affect my floating mortgage rate?

Floating mortgage rates respond directly to RBNZ Official Cash Rate changes. When the OCR is cut, floating rates typically drop by the same amount (25 or 50 basis points) within a few days.

Weathertightness — Case Study

A Home With Weathertightness Issues.
Financed With Remediation Costs Included.

The Situation

The problem.

Nathan and Grace fell in love with a 1998-built monolithic-clad home in Auckland's Mount Albert — exactly the era and construction style associated with New Zealand's well-known weathertightness ("leaky home") issues. A pre-purchase building report confirmed moisture ingress risk and recommended a full re-clad, estimated at $95,000.

Their first bank declined the application outright once the building report was disclosed — citing the property as an unacceptable security risk in its current condition, full stop, regardless of the couple's income or deposit strength.

Nathan and Grace still wanted the property (priced accordingly below comparable weathertight homes in the same street) but needed a lender willing to finance both the purchase and the remediation as a combined package.

The Finch Approach

How we solved it.

Remediation scope and quote formalisationWe had Nathan and Grace obtain a fixed-price quote from a qualified re-cladding specialist, converting the building report's estimate into a bankable, itemised scope of works — a requirement for any lender to consider remediation-inclusive lending.

Lender selection for as-if-complete valuationWe identified a lender that will value a weathertightness-affected property on an "as-if-remediated" basis when a fixed-price contract and qualified building consent are in place, rather than only lending against the property's current, discounted condition.

Staged drawdown structuringThe loan was structured with an initial drawdown to fund settlement at the discounted purchase price, and a second staged drawdown released against the remediation contract as work milestones were completed and signed off.

Council consent and LBP coordinationWe worked with Nathan and Grace's building consultant to ensure the remediation used a Licensed Building Practitioner and had council consent lodged before the lender would confirm the staged drawdown facility.

The Outcome

The result.

Approval was issued in 26 days once the fixed-price remediation contract was in place — a deal the first bank had refused outright. Nathan and Grace settled on the $780,000 purchase, with remediation funded as part of the same facility rather than requiring separate finance.

The re-clad was completed within 5 months, and the property was re-valued post-remediation at a level consistent with weathertight comparable sales in the same street, protecting their long-term equity position.

Grace's feedback: "We thought we'd lost the house the moment the first bank said no. Finch found a lender who understood exactly how to finance a property mid-remediation, not just a finished one."

Useful NZ sources: the Reserve Bank of New Zealand for current lending policy, and Kāinga Ora for first-home support schemes.
