Think you need $150,000 saved before you can buy a house? You don’t. If you’re looking at a new build in New Zealand, the rules are different — and they’re in your favour.
Most first home buyers assume they need a 20% deposit. For a $750,000 home, that’s $150,000. But for brand new properties, banks can lend up to 95% of the purchase price. That means a 5% deposit — as little as $30,850 for a $617,000 turnkey townhouse in Christchurch.
This guide explains exactly how 5% deposit home loans work in New Zealand, what you need to qualify, and how Christchurch first home buyers are using this pathway right now.
Why New Builds Get Special Treatment from Banks
The Reserve Bank of New Zealand (RBNZ) sets Loan-to-Value Ratio (LVR) rules that limit how much banks can lend to borrowers with small deposits. For existing homes, most banks require at least 20% deposit (80% LVR).
But here’s the key difference: new builds are exempt from LVR restrictions. Loans for brand new properties don’t count towards the bank’s LVR lending cap. This means banks are far more willing to approve 5% or 10% deposit mortgages for new builds because these loans don’t use up their limited low-deposit lending quota. We’ve broken down exactly how this works in our LVR new build exemption explained guide.
What counts as a “new build”?
To qualify for the LVR exemption, the property must meet specific criteria:
- A dwelling being purchased from the developer or builder on a fixed-price contract
- The Code Compliance Certificate (CCC) must have been issued within the last 12 months
- Turnkey packages — where you buy a completed, move-in-ready home — qualify perfectly
All of Tailored Homes’ Four Seasons Estate Wigram townhouses and Prebbleton house-and-land packages meet these requirements.
How Much Deposit Do You Actually Need?
Here’s what the numbers look like in practice for Christchurch new builds:
| Property | Price | 5% Deposit | 10% Deposit |
|---|---|---|---|
| 2-bed townhouse (Wigram) | $617,000 | $30,850 | $61,700 |
| 3-bed townhouse (Wigram) | $709,000 | $35,450 | $70,900 |
| 4-bed home (Prebbleton) | $1,039,900 | $51,995 | $103,990 |
With a 5% deposit, the gap between “renting forever” and “homeowner” might be smaller than you think.
3 Ways to Build Your 5% Deposit
1. Kainga Ora First Home Loan
The government-backed First Home Loan (administered by Kainga Ora, formerly Housing New Zealand) allows eligible buyers to purchase with just a 5% deposit. Key details:
- Deposit required: 5% minimum
- Income cap: $95,000 for a single buyer, $150,000 for two or more buyers (before tax)
- House price cap: Varies by region — Christchurch cap is $500,000 for existing homes, but no price cap for new builds
- Participating banks: ANZ, ASB, BNZ, Kiwibank, TSB, Westpac, SBS, and The Co-operative Bank
- Who qualifies: First home buyers (never owned property before) who intend to live in the home
The “no price cap for new builds” is huge — it means even our $709,000 Wigram townhouses qualify, whereas an existing home at that price wouldn’t.
2. KiwiSaver First Home Withdrawal
If you’ve been contributing to KiwiSaver for at least 3 years, you can withdraw most of your balance to put towards your deposit. You must leave a minimum of $1,000 in your account.
Many Christchurch first home buyers combine their KiwiSaver withdrawal with the First Home Loan to reach their 5% deposit. For example:
- KiwiSaver balance after 5 years of contributions: ~$15,000-$25,000
- Partner’s KiwiSaver: ~$15,000-$25,000
- Combined: $30,000-$50,000 — enough for a 5% deposit on most new builds
3. Family Gifting (The “Bank of Mum and Dad”)
Banks accept gifted funds towards your deposit, provided the gift is documented correctly. You’ll need a signed deed of gift confirming the money is a gift, not a loan.
This is more common than you might think — we’ve written about how families are using this strategy to help the next generation get on the property ladder while making a sound investment.
What Banks Check Beyond Your Deposit
Having 5% deposit is the starting point, not the finish line. Before you start house-hunting, get pre-approved — see our step-by-step bank pre-approval guide for new builds. Banks also assess:
- Repayment ability: Your income minus all expenses and existing debts (credit cards, car loans, Afterpay). Banks typically want your mortgage repayments under 30-35% of your gross income.
- Credit history: No defaults, missed payments, or undisclosed debts. Check your credit report at Centrix before applying.
- Stable employment: At least 6-12 months in your current role. Self-employed buyers usually need 2 years of financial records.
- Genuine savings: Some banks want to see evidence you’ve saved at least part of the deposit yourself (not all gifted). KiwiSaver contributions count as genuine savings.
Budget for extra costs
On top of your deposit, set aside roughly $3,000-$5,000 for:
- Solicitor/conveyancing fees: ~$1,500-$2,500
- Valuation fee: ~$600-$800
- Loan application fee (some banks): ~$0-$500
- Insurance (contents + house): first month upfront
With a turnkey new build, you skip the building inspection and LIM report costs that existing-home buyers face.
Why a New Build Beats an Existing Home for First Buyers
Beyond the deposit advantage, buying a new build in Christchurch gives you:

First Home Grant: Up to $10,000 Extra
On top of the First Home Loan, you may qualify for the Kainga Ora First Home Grant:
- New build: $2,000 per year of KiwiSaver contribution (max $10,000 per person after 5+ years)
- Existing home: $1,000 per year (max $5,000)
- Couples: Both partners can apply — potentially $20,000 combined for a new build
Income and house price caps apply. For Christchurch new builds, the income caps are the same as the First Home Loan ($95,000 single / $150,000 combined).
Your Next Step
Buying a house with a 5% deposit isn’t a loophole — it’s a deliberate policy designed to help New Zealanders into new, quality homes.
