NZ Mortgages & Home Loans — Guides, Calculators and Rates

Updated

Buying a home in New Zealand is one of the largest financial decisions you’ll ever make — and a mortgage will shape your finances for the next 25–30 years. MoneyBalance covers every stage, from understanding how home loans work through to refinancing and paying off your mortgage faster.

The NZ Home Loan Landscape

New Zealand’s mortgage market is shaped by rules that don’t exist in most other countries. The Reserve Bank of New Zealand (RBNZ) sets loan-to-value ratio (LVR) restrictions, which cap how much banks can lend to high-LVR borrowers as a share of their total lending book. The practical effect for most buyers: you need at least a 20% deposit to qualify for a standard home loan from a major bank. First home buyers can access the government-backed First Home Loan through Kāinga Ora with just a 5% deposit, subject to income caps (Kāinga Ora removed regional house price limits nationwide from 1 June 2022, so there’s no longer a property price ceiling).

In 2024, the RBNZ introduced debt-to-income (DTI) restrictions, limiting most owner-occupier mortgages to 6× the borrower’s gross annual income (banks can make up to 20% of new lending above it). For a household earning $130,000 per year, 6× income is $780,000. Combined with interest rates that — while lower than the 2023–24 peak — remain elevated by historical standards (one-year fixed rates are around 5–6% as of mid-2026), borrowing capacity is substantially tighter than during the low-rate period of 2020–21.

NZ mortgage terms are typically 25–30 years, but most borrowers don’t hold a single rate for the full term. Instead, Kiwi borrowers refix at regular intervals — commonly every 6 to 18 months — choosing a new fixed term or switching to a floating rate. This means mortgage strategy is an ongoing, active decision. The choice between a short fixed term (six months, one year) and a longer term (two to three years) depends on your view of where rates are heading, your financial flexibility, and how much certainty you need.

The five major banks — ANZ, ASB, BNZ, Westpac, and Kiwibank — dominate the mortgage market. Non-bank lenders (Liberty, Resimac, NZCU) serve borrowers who don’t meet standard bank criteria, typically at higher rates. Mortgage brokers, who can access multiple lenders simultaneously, are used by the majority of first home buyers and increasingly by refinancers seeking a better rate.
