Frequently Asked Questions

How much deposit do I need for a home in New Zealand?

Most lenders in New Zealand require a 20% deposit for a standard home loan. With the Kainga Ora First Home Loan, you may buy with as little as 5% deposit on a property under the regional price cap ($350k-$850k depending on area). KiwiSaver First Home Withdrawal lets you pull out your savings (minus $1,000 minimum) after 3 years of contributions.

What is the average mortgage rate in New Zealand?

Mortgage rates in New Zealand as of 2024: 1-year fixed 6.5-7.5%, 2-year fixed 6.2-7.0%, 3-year fixed 5.8-6.8%, 5-year fixed 5.5-6.5%. Floating rates are 7.5-8.5%. Rates are influenced by the OCR (Official Cash Rate, currently 5.5%). Comparison tables from interest.co.nz and Canstar show current offers.

How much can I borrow in New Zealand?

Lenders typically offer 4-5x your gross household income. With a combined income of $130,000, you could borrow approximately $520,000-$650,000. The CCCFA (Credit Contracts and Consumer Finance Act) requires lenders to assess affordability comprehensively, including your living expenses, existing debts, and ability to handle rate rises of 2-3%.

What government schemes help first-home buyers in New Zealand?

Kainga Ora First Home Loan (5% deposit, lower LVR), KiwiSaver First Home Withdrawal (withdraw contributions after 3 years), and the First Home Grant (up to $10,000 for individuals, $20,000 for couples who have contributed to KiwiSaver for 3+ years and meet income caps). Owner-built and newly built homes may qualify for additional grants.

What ongoing costs come with home ownership in New Zealand?

Ongoing costs include: council rates ($2,000-$4,000/year), home and contents insurance ($1,500-$3,000/year), maintenance (1% of property value annually), and potentially body corporate fees for apartments ($3,000-$6,000/year). There is no property tax or stamp duty in New Zealand outside of specific regional council charges.

How does the bright-line test affect property investment?

The bright-line test means you pay tax on gains from residential property sold within 10 years of purchase (5 years for new builds, 2 years for main home and inherited property). The gain is added to your income and taxed at your marginal rate. This primarily affects property investors and second-home owners, not owner-occupiers.
