Mortgage rates in New Zealand move with the Reserve Bank's Official Cash Rate (OCR) and change every few weeks as banks reprice their fixed and floating home loan offers. As of November 2026, one-year fixed rates from the main banks sit roughly between 4.9% and 5.2%, with the OCR at 2.25% after a series of cuts through 2025-26. Rates change often, so always confirm the current number directly with a lender or on a comparison site before signing.
Fixed vs floating mortgage rates
A fixed rate locks in your interest rate for a set term, usually 6 months to 5 years, so your repayment stays the same even if the OCR moves. A floating (variable) rate moves with the market immediately, which suits borrowers who expect rates to fall further or who want the flexibility to make extra repayments without break fees. Many New Zealand borrowers split their mortgage between a fixed and a floating portion to balance certainty with flexibility.
What moves mortgage rates in NZ
- The Reserve Bank's OCR decisions, announced roughly every 6 weeks
- Bank funding costs on wholesale and international markets
- Your deposit size, loan-to-value ratio (LVR) and credit history
- Whether you negotiate directly or go through a mortgage broker
Example repayment at current rates
On a $500,000 mortgage over a 30-year term at a 5.0% one-year fixed rate, the repayment is approximately $2,684 per month (principal and interest). Drop the rate to 4.5% and the repayment falls to roughly $2,533 per month, a difference of about $151 a month or over $1,800 a year, which shows why even a 0.5 percentage point difference is worth negotiating over.
How to find the best mortgage deal
- Check your LVR: borrowers with more than 20% deposit usually access the lowest advertised rates
- Compare at least 3-4 lenders, including smaller challenger banks, which sometimes undercut the big four
- Ask your bank for a "retention" rate when a fixed term ends, before you accept the standard rollover rate
- Consider a mortgage broker, who can access rates not always advertised publicly and does not charge the borrower directly
Frequently asked questions
Is now a good time to fix my mortgage in New Zealand?
With the OCR at 2.25% and most economists expecting it to stay low into 2027, many borrowers are currently splitting between a shorter fixed term (6-12 months) and a floating portion, rather than locking in a long fixed term. Your decision should depend on your own risk tolerance and cash flow, not just the headline rate.
What credit score do I need for the lowest mortgage rate?
Banks do not publish a fixed minimum score, but a clean credit history, a deposit above 20% and stable income give you access to the advertised "special" rates rather than a higher rate loaded for risk.
Can I switch banks partway through a fixed mortgage term?
Yes, but breaking a fixed rate early usually triggers a break fee calculated on how much rates have moved since you fixed. Get a break cost estimate from your current bank before committing to switch.
