New Zealand mortgages are offered by major banks (ANZ, ASB, BNZ, Kiwibank, Westpac) and non-bank lenders. Most borrowers choose a fixed rate for 1-2 years, then refix at maturity. Floating rates offer flexibility for extra repayments but are typically 1-1.5% higher. The RBNZ's OCR cuts through 2025-2026 have brought fixed rates down from 2023 peaks of 7%+ to approximately 6.0-6.8% for standard fixed terms.
A 20% deposit is the standard threshold to avoid the Low Equity Premium (LEP) — a surcharge of 0.25-1.75% applied to loans with LVR above 80%. First-home buyers may access the First Home Loan scheme (5% deposit) or use KiwiSaver for their deposit. Use our KiwiSaver Calculator to see how much you can put toward a home purchase.
A NZ$150,000 deposit on a NZ$750,000 home gives a NZ$600,000 mortgage at 80% LVR — avoiding the LEP. At 6.5% over 30 years, monthly repayments are NZ$3,792 with NZ$765,120 in total interest. Adding NZ$200/month in extra repayments saves approximately NZ$120,000 in interest and cuts ~5 years off the loan.

At 6.5% over 30 years, approximately NZ$3,792/month. Total interest is about NZ$765,120. A 25-year term raises the payment to ~NZ$4,060 but saves ~NZ$153,000.

With RBNZ cutting the OCR, shorter fixed terms (1-2 years) let you refix at potentially lower rates. Floating is more expensive but offers flexibility for extra repayments. Many borrowers split.
Yes. After 3+ years membership, withdraw most of your balance for a first home. Plus the First Home Grant — up to NZ$10,000 (new build) or NZ$5,000 (existing home).
A surcharge of 0.25-1.75% if your deposit is under 20% (LVR above 80%). This can add thousands per year. Aim for 20% deposit to avoid it.
3-5× gross income is considered affordable. NZ's actual ratio averages 7-8× nationally and 9-10× in Auckland, making affordability challenging.
Deposits under 20% trigger the Low Equity Premium — 0.25-1.75% extra on your rate. On NZ$600K, that could be NZ$1,500-10,500 extra per year. Aim for 20%.
Combine KiwiSaver withdrawal with the First Home Grant (up to NZ$10,000 new build / NZ$5,000 existing) to boost your deposit significantly.
With RBNZ cutting the OCR through 2025-2026, shorter fixed terms (1-2 years) let you refix at potentially lower rates. Avoid locking in for 5 years in a declining rate cycle.
Even NZ$200/month extra on NZ$600K at 6.5% saves ~NZ$120,000 in interest and cuts ~5 years off the loan. Most fixed-rate loans allow up to 5% extra annually without penalty.
Don't just roll over with your current bank. Compare rates across all lenders at each refix — even 0.2% lower saves thousands over the next fixed period.
A revolving credit portion lets your savings reduce the loan balance you pay interest on — similar to an offset account. Good for disciplined savers who want flexibility.
