Getting a Mortgage in New Zealand: What Buyers Need to Know

7 min read

Quick Answer

New Zealand residents typically need a 20 percent deposit for a standard mortgage, though some lenders accept 10 percent with Lenders Mortgage Insurance. Non-resident buyers usually need 30 to 40 percent deposit and must demonstrate income from acceptable sources. Pre-approval lasts 3 to 6 months. Major lenders include ANZ, ASB, BNZ, Westpac, and Kiwibank, plus specialist lenders for complex or foreign-income cases.

Key Takeaways

Resident buyers typically need a 20 percent deposit; non-residents need 30 to 40 percent.

Pre-approval gives you a conditional maximum loan amount valid for 3 to 6 months.

Foreign income is assessed more conservatively — expect tighter lending criteria.

A mortgage broker can access multiple lenders and find the best rate for your situation.

Interest rates in New Zealand are typically floating or fixed for 1 to 5 years.

How NZ Mortgages Work

New Zealand mortgages are similar to those in Australia and the UK. You can choose between floating (variable) rates and fixed rates, typically fixed for 1, 2, 3, or 5 years. At the end of the fixed period, you can refix or move to floating. Most lenders offer table loans (regular principal and interest payments), interest-only loans (for a limited period), or revolving credit facilities. Loan terms are typically 25 to 30 years.

Deposit Requirements

New Zealand banks generally require a 20 percent deposit for a standard residential mortgage (80 percent loan-to-value ratio). Some lenders will accept a 10 percent deposit with Lenders Mortgage Insurance (LMI), which adds a one-off premium to your loan. For non-resident buyers, deposit requirements are typically 30 to 40 percent, and income verification from overseas can be more demanding. Luxury properties above $3 million may face lower LVR limits from some lenders.

Pre-Approval

Pre-approval (also called conditional approval) gives you a maximum loan amount based on your income, assets, and credit history. It is valid for 3 to 6 months and shows sellers and agents you are a serious, financed buyer. Pre-approval is not a guarantee — final approval depends on the bank's valuation of the specific property. Get pre-approval before you start seriously viewing properties so you know your budget.

Foreign Income and Non-Resident Borrowing

If your income is earned overseas, NZ banks will assess it more conservatively. Most banks discount foreign income by 20 to 30 percent to account for currency risk and verification difficulties. You will need comprehensive documentation: payslips, tax returns, bank statements, and sometimes an accountant's letter. Some lenders specialise in foreign-income lending and may offer better terms than the major banks. A mortgage broker experienced with international clients is invaluable.

Choosing a Lender

The major New Zealand banks are ANZ, ASB, BNZ, Westpac, and Kiwibank. Non-bank lenders (Squirrel, Resimac, Pepper Money) offer more flexible criteria for borrowers who do not meet bank requirements. A mortgage broker can access multiple lenders and compare rates and terms. For luxury properties, private banking divisions of the major banks offer tailored lending with higher loan limits and personalised service.

Using a Mortgage Broker

A mortgage broker acts as your advocate, comparing loans across multiple lenders and handling the application process. Their service is free to you — they are paid by the lender on settlement. For international buyers or complex financial situations, a broker is particularly valuable. Look for a broker registered with the Financial Advice New Zealand and experienced with high-value or foreign-income lending.
