Saving for a house deposit in New Zealand: what you actually need

Buying a home in New Zealand is one of the largest financial decisions you'll make. Understanding exactly what you need — not just the deposit, but all the associated costs — prevents nasty surprises and helps you plan with confidence.

The 20% deposit: why it's the target

Most lenders in New Zealand require a 20% deposit for standard home loans. With a lower deposit (down to 10% in some cases), you'll likely face stricter lending criteria and higher interest rates, or pay a low-equity premium. The 20% threshold is worth aiming for.

In practical terms: for a $750,000 home (roughly the national median as of 2026), a 20% deposit is $150,000. For a $600,000 home, it's $120,000. These are the savings targets — not including legal fees, moving costs, and other purchase expenses.

KiwiSaver and the First Home Grant

If you're a first home buyer, you have access to two important tools:

KiwiSaver First Home Withdrawal

After three or more years of contributing to KiwiSaver, you can withdraw most of your balance (keeping at least $1,000) toward a first home purchase. This can add tens of thousands of dollars to your deposit without additional saving.

First Home Grant (subject to eligibility)

Eligible first home buyers may receive a grant from the government — check Kāinga Ora for current criteria and amounts, as these change periodically.

The costs people forget

Beyond the deposit, budget for:

• Legal fees: $1,500–$3,000 for a solicitor to handle the purchase
• Building inspection: $500–$900 — essential, not optional
• LIM report: $200–$400
• Moving costs: $500–$3,000 depending on how much you own and how far you're moving
• Immediate repairs or maintenance: highly variable, but budget at least $2,000–$5,000 for the unexpected

How long will it take?

The honest answer depends entirely on your income, expenses, and the property market where you want to buy. At $1,500 a month in savings, reaching a $150,000 deposit takes just under 8.5 years without KiwiSaver or investment growth. With KiwiSaver and returns, significantly less.

The most useful thing you can do right now is calculate your actual monthly savings capacity and set a specific target. Even if the timeline feels long, a clear plan beats anxious uncertainty every time.
