Comparing Home Loan Rates in NZ for 2025

The mortgage you sign today shapes your finances for years. With interest costs the single biggest line item for most New Zealand households, even a small rate difference compounds into thousands of dollars over a typical term.

Fixed vs floating

Most Kiwi mortgages are fixed for one to five years, with a smaller floating portion that can be repaid faster without break costs. Fixed rates buy certainty; floating rates buy flexibility. A common split is to fix most of the loan and keep a smaller floating piece for extra repayments.

What actually drives the rate you get

• Your loan-to-value ratio — anything below 80% typically gets the sharpest rates.
• How much business you're bringing — larger loans negotiate harder.
• Whether you're a new customer (cash contributions are often available).
• Whether you're using a broker who can pit lenders against each other.

Cash contributions vs lower rate

Banks often offer cash contributions of around 0.6% to 1.0% of the loan amount when you take out or refinance a mortgage. That cash is real, but it usually comes with a clawback if you leave within three or four years. Always model the total cost — rate plus contribution minus any clawback — not just the headline.

Don't forget the structure

The right structure matters as much as the rate. Splitting fixed terms so they don't all roll at once spreads your refixing risk. A revolving credit or offset facility used carefully can shave years off the loan.

Key takeaways

• Compare advertised rates with cash contributions and clawbacks included.
• A split fixed/floating structure gives certainty and flexibility.
• LVR under 80% unlocks the sharpest pricing.
• Refixing dates are a renegotiation opportunity, not a formality.
