Quick take: Your house deposit affects home loan approval, interest rates, and fees. The minimum preferred deposit for an existing home is often 20% of the property’s purchase price; however, low deposit pathways (e.g., First Home Loan) or low deposit loans are available if you meet the home loan eligibility criteria and the lender’s lending criteria.
What a deposit does (and why lenders care)
Your home loan deposit reduces the amount you borrow (loan) and sets your loan-to-value ratio (LVR). A lower LVR can mean sharper interest rates and fewer fees, because the bank is taking on less risk. Lenders also assess your financial position, credit history, income and expenses to check home loan affordability for the residential property you’re buying.
Deposit requirements in NZ at a glance
- 20% deposit (80% LVR): Typical for owner-occupiers purchasing an existing home. Most home loan lenders prefer a minimum 20% deposit.
- 10% deposit: Sometimes possible with most lenders if you’re strong on servicing and meet the lenders specific criteria; pricing may include a low-equity margin on top of a higher base rate until you reach 20%.
- 5% deposit: Possible for first home buyers via First Home Loan with a participating lender (subject to eligibility criteria). Kāinga Ora underwrites the First Home Loan, allowing banks to accept a 5% deposit. Pricing is often based on special rates with a mortgage insurance premium added to your loan amount.
- Investment property: It often requires a larger deposit, typically 30% unless you’re buying a new build, than a first-home purchase due to higher risk and different lending criteria.
Rule of thumb: The deposit you’ll need scales with the property’s purchase price. On an $800,000 house, how much deposit is 5% ($40k), 10% ($80k), or 20% ($160k).
5% vs 10% vs 20% — which is right for you?
5% deposit: get into your first home sooner
Kāinga Ora underwrites the First Home Loan, allowing lenders to accept lower deposits. Best for first-time home buyers who have a strong income and want to get into their first property sooner. You may be able to get government help to buy or build your first home in New Zealand. You will also pay a mortgage insurance premium under First Home Loan either up front or added to your loan. Expect stricter lending criteria and more detailed documentation when working with a participating lender.
10% deposit: a workable middle ground
Opens up options with other lenders beyond First Home Loan. Pricing may still reflect higher LVR risk until you reach 20% equity, but it can be a practical step onto the property ladder.
20% deposit: the cleanest pricing
Often, the best interest rates, fewer fees, and more choices are available from lenders. Stronger negotiating power on the structure and refix options.
KiwiSaver: using savings toward your deposit
Suppose you’re a KiwiSaver member for at least three years. In that case, you can usually withdraw funds via KiwiSaver first home withdrawal to boost your home deposit (you’ll need to leave the $1k government contribution in your KiwiSaver account). These KiwiSaver savings can combine with your cash savings and gifts to meet deposit requirements for your first property.

Lenders’ pricing & “mortgage insurance” in NZ
NZ doesn’t typically use Australian-style lender’s mortgage insurance on standard bank loans. Instead, when borrowing with a low deposit (high Loan-to-Value Ratio, or LVR), banks may charge a low-equity interest margin or increase your base rate. Under the First Home Loan scheme, a specific mortgage insurance premium applies. The higher the LVR, the more you can expect to pay in rate/fee trade-offs until your equity improves.
Worked examples: deposit you’ll need
- $600,000 property → 5% = $30,000; 10% = $60,000; 20 = $120,000
- $800,000 property → 5% = $40,000; 10% = $80,000; 20% = $160,000
- $1,000,000 property → 5% = $50,000; 10% = $100,000; 20% = $200,000
Remember: the purchase price drives the dollars. We can model various LVRs, structures, and interest rates, so you can choose with confidence.

FAQ (quick answers for home buyers)
How much deposit for mortgage NZ?
It depends on the property type, your profile and lending criteria. Many aim for 20%, but low deposit pathways (5–10%) exist with the right lenders and scheme settings.
Can I buy my first home with 5%?
Potentially, via a First Home Loan with a participating lender, if you meet the eligibility criteria and pass the servicing tests.
Is 10% enough for an existing home?
Sometimes. You may face higher pricing until you reach a 20% equity stake. We’ll compare lenders so you can pick the best fit.
What about an investment property?
Expect stricter deposit requirements compared to a first home, due to higher risk settings.
Conclusion: choosing the right deposit in NZ
Your house deposit determines your LVR, affects your interest rates and fees, and influences which lenders will approve your application. A 20% deposit usually unlocks the sharpest pricing; 10% can be a practical step onto the property ladder; and 5% may be possible for first-home buyers via the First Home Loan (subject to eligibility criteria and scheme costs). Combine KiwiSaver first home withdrawal, disciplined savings, and smart structure choices to reach a suitable property sooner—without overextending your financial position. The rules (LVR/DTI/policy) evolve over time, so model scenarios and seek advice before making a commitment.
