Deposit Requirements in NZ: What You Need to Know
Your deposit is one of the biggest factors in securing a home loan. It affects which lenders will consider your application, the interest rates you’re offered, and the type of loan structure available. This guide explains how deposits work in New Zealand, what minimum amounts are required, and the options available if you don’t have 20%. At Taranaki Home Loans, we help buyers understand the rules and find solutions that make homeownership achievable.
Standard Deposit Requirements
Most banks in New Zealand prefer a 20% deposit when lending on existing homes. This reduces the lender’s risk and may give you access to lower interest rates. For example, if you’re buying a home worth $600,000, a 20% deposit would be $120,000.
A deposit at this level generally means fewer restrictions, easier approval, and access to a wide range of lenders. Taranaki Home Loans can check which banks are offering the sharpest rates and terms for borrowers with 20% deposits.
Low Deposit Options
Not everyone can save 20%, especially first-home buyers. In New Zealand, there are pathways for borrowers with smaller deposits:
10% deposits
Some banks lend to borrowers with 10% deposits, especially under Kāinga Ora’s First Home Loan scheme.
5% deposits
In certain cases, Kāinga Ora guarantees allow lending with as little as 5%.
New builds
Some banks allow lower deposits when purchasing new builds, as these loans have different risk rules.
While possible, low-deposit loans may come with stricter conditions, higher rates, or limited lender choice. At Taranaki Home Loans, we check which banks are accepting low-deposit applications and whether you qualify.
Using KiwiSaver and Other Sources
Many first-home buyers use KiwiSaver savings toward their deposit. You can usually withdraw most of your balance if it’s your first property, provided you meet the eligibility rules. You may also qualify for a Kāinga Ora First Home Grant if you’ve been contributing to KiwiSaver for at least three years.
Other deposit sources include:
- Gifting from family
A parent or relative may contribute part of the deposit. - Savings accounts
Lenders prefer to see regular savings, which show good financial habits. - Equity from another property
If you already own a home, equity can be used as a deposit for your next property. - Guarantor support
In some cases, a family member may act as a guarantor, using their own home’s equity to help secure your loan.
Taranaki Home Loans helps clients combine these sources into an acceptable deposit for lenders.
How Deposits Affect Interest Rates
The size of your deposit directly impacts your interest rate. Borrowers with higher deposits are often rewarded with lower rates, as the loan is seen as less risky. With smaller deposits, banks may apply a margin to the rate or limit your fixed-term options.
This is why it’s important to compare carefully. Taranaki Home Loans runs side-by-side comparisons across banks so clients can see the real cost of different deposit levels.
Conclusion & Next Steps
Your deposit is a key part of your home loan application. Whether you’re aiming for the standard 20% or looking into low-deposit options, it’s important to know the rules and what lenders require.
