What deposit do you really need to buy a home in New Zealand?

Buying your first home in New Zealand often feels like a battle of the "20% rule." While 20% remains the gold standard for the best rates and easiest approvals, it’s far from the only path.

As a mortgage adviser, I see too many people waiting years to hit a 20% target when they could have been in their own home much sooner. Here is the blunt breakdown of your deposit options in the current NZ market.

1. The 5% Deposit: The Fast Track

If you have a bit of a deposit laying around in your Kiwisaver, and put a high value on owning your own home as soon as possible, this is for you.

• Kāinga Ora First Home Loan: This is the most popular 5% option. It’s a standard bank loan underwritten by the government, meaning you get "special" low interest rates despite your low deposit.

  • Income Caps: $95k or less for individuals; $150k or less for couples/those with dependents.

• Main Bank Schemes: Some banks offer their own 5% lending outside of Kāinga Ora. These often have higher interest rates and do not offer pre-approvals, making them harder to plan around.

2. The 10–19% Deposit: The Middle Ground

If you’ve saved more than 5% but aren't at the magic 20% mark, you fall into "Low Equity" lending.

• Pre-Approval: Most banks can offer a 60-day pre-approval for these loans.

• The Cost: Because you have less than 20% equity, banks will usually charge a Low Equity Margin (LEM). This means your interest rate will be roughly 0.25% to 0.75% higher than the advertised "special" rates.

• New Builds: If you are buying a turnkey property or building from scratch, some banks are much more flexible with a 10% deposit and you may actually be eligible for special interest rates even with a 10% deposit.

3. The 20% Deposit: The Golden Ticket

This is where the banks roll out the red carpet.

• Best Rates: You qualify for the absolute lowest "special" rates immediately.

• Cashback: Banks are currently offering strong cash contributions to entice 20% deposit buyers.

• Fewer Hurdles: You typically won’t need a registered valuation unless it's a private sale or a complex build.

Where does the money actually come from?

You don't need to have all this sitting in a savings account. Most successful first-home deposits in NZ are a "cocktail" of sources:

• KiwiSaver: You can withdraw almost everything except $1,000 after being a member for 3 years.

• Gifts: "Bank of Mum and Dad" is common. Most banks accept gifted deposits as long as there’s a signed gift letter.

• Flatmate Income: A secret weapon for affordability. One flatmate paying $200/week can boost your buying power by roughly $80,000 in the eyes of some lenders.
