Working out how much deposit to build a house NZ buyers need in Canterbury is harder than it sounds, because the answer depends on the loan structure, the contract type and whether the bank treats your purchase as an exempt new build. At Tailored Homes, we have spent 16 years and delivered more than 100 homes across Christchurch and Canterbury, and we regularly see buyers weighing low-maintenance freehold townhouses at 41 Deal Street, Wigram, against standalone 3- and 4-bedroom homes in Prebbleton. We are builders, not lenders, so we cannot promise approvals, but we can show you the real 2026 deposit maths.
With the Reserve Bank of New Zealand holding the Official Cash Rate at 2.25% on 8 April 2026, more buyers are re-running the numbers. The first question is still the same: how much deposit do you really need to build a new home in New Zealand?
The short answer
In 2026, a 5% deposit can be enough for some new builds in New Zealand, but 10% is more typical and some lenders will still want 20% depending on the buyer, the contract and the bank’s own policy.
On a $650,000 new home, the headline numbers are simple: 5% is $32,500, 10% is $65,000, and 20% is $130,000. The reason buyers get confused is that the minimum possible deposit and the deposit most likely to get a smooth approval are not always the same thing.
- Best-case new-build exemption: $32,500 deposit.
- Common owner-occupier target: $65,000 deposit.
- Conservative lender or tougher profile: $130,000 deposit.
In our experience, first-home buyers usually get the cleanest path with a fixed-price turnkey or house-and-land package, good bank conduct and a cash buffer on top of the bare minimum.
The 5% new-build deposit explained
A 5% deposit is possible because eligible new builds are exempt from the Reserve Bank of New Zealand’s loan-to-value ratio limits, not because banks have stopped caring about risk.
As of 2026, the Reserve Bank of New Zealand (RBNZ) says owner-occupier lending is generally treated as high-LVR above 80% and investor lending above 70%. The same page also says the LVR rules do not apply to construction loans or to a newly built home bought from a developer within 6 months of completion. The RBNZ’s debt-to-income rules use the same new-build carve-out.
That is why a genuine new build can sometimes be financed with only 5% down. In practice, banks still want evidence that the property qualifies and that you can service the loan. That usually means a signed sale and purchase agreement or build contract, plans and specifications, a fixed-price or tightly documented inclusions list, proof of your deposit, builder details, a timeline, and sometimes a registered valuation.
If you want the policy background in plain English, read our 5% deposit new-build guide for Christchurch buyers and companion LVR exemption guide. The key point is simple: 5% is possible, but it is never automatic.
Different deposit thresholds by buyer type
The deposit you need depends as much on who you are as on what you are building.
Owner-occupier first-home buyer
A first-home buyer living in the property has the best shot at 5%. Some borrowers get there through the new-build exemption alone, while others use a Kāinga Ora-backed loan. Even so, many banks are more comfortable once you are closer to 10%, especially if your income is tight or you have other debt.
Owner-occupier upgrader
Upgraders are usually assessed on a mix of cash deposit, usable equity and whether their existing home has sold. A 10% to 20% effective deposit is common here, especially if the bank has to allow for bridging finance, overlapping repayments or a build starting before the old home settles.
Investor buying a new build
Investors often assume the 30% rule still applies everywhere. The nuance is that the RBNZ new-build exemption can remove the macroprudential floor, but the bank can still apply its own rental, servicing and cash-buffer rules. In 2026, 10% to 20% is a more realistic planning range for many investor new-build applications, and some lenders will still want more.
Kāinga Ora First Home Loan
The Kāinga Ora First Home Loan still exists in 2026 and can reduce the required deposit to 5%, but there are caveats. You must meet income caps, buy as an owner-occupier, and satisfy the lender’s own credit policy. Kāinga Ora’s current criteria include income of up to $95,000 for a single buyer without dependants, up to $150,000 for a single buyer with dependants, or $150,000 combined for two or more buyers, plus a 1.2% lender’s mortgage insurance premium. Kāinga Ora also notes that some participating lenders allow builds and some do not, so check this early.

Where the deposit can come from
In New Zealand, your deposit can be a mix of cash, KiwiSaver, gifts and equity, but every source has timing rules.
- Savings: Clean savings history is still the easiest deposit source for a bank to assess, especially if you are using a progress-payment contract.
- KiwiSaver withdrawal: Inland Revenue says eligible first-home buyers can withdraw their own contributions, employer contributions, government contributions and investment earnings after at least three years in KiwiSaver, but must leave $1,000 in the account. Talk to your provider early, because withdrawal paperwork can hold up contract timing.
- First Home Grant: Older NZ articles still mention it, but they are outdated. Kāinga Ora’s home ownership report confirms new applications for the First Home Grant closed at 1pm on 22 May 2024, so first-home buyers should not include it in a 2026 deposit plan.
- Gifted deposit: A parent-bank gift can work, but the lender will usually want a signed gift letter and proof that the money is not an undisclosed repayable loan.
- Equity from an existing property: Upgraders and some investors can top up against current equity instead of producing all of the deposit in cash, but the bank will still test the full debt position.
If you are using a First Home Loan, Kāinga Ora says the 5% minimum can include savings, gifts and first-home withdrawals. That flexibility helps, but it does not remove the lender’s right to say no.
The turnkey vs progress payments twist
With new builds, the deposit is not always one lump sum on one day; the contract structure changes the cashflow.
Turnkey
A turnkey contract is usually the easiest low-deposit path. You commonly pay a smaller deposit when you sign, then the balance on completion. For the bank, that can look more like a normal purchase of a finished home, which is one reason turnkey deals are popular with first-home buyers.
Progress payments
A land-plus-build contract works differently. You may settle the land first, then the bank funds the build in stages such as foundations, frame, lock-up, linings or services, and final completion. Your deposit or equity is usually used first, and the bank draws the rest over time. Exact stage names vary by lender and builder, so read the cashflow schedule carefully.
At Tailored Homes, many buyers prefer fixed-price contracts because the bank, valuer and buyer are all working off the same number. That reduces surprises.
Beyond the deposit: the other costs buyers forget
The deposit is only part of the cash you need to start a new build.
- Solicitor and loan setup costs: You will usually need legal work for the sale and purchase agreement, finance documents, KiwiSaver withdrawal paperwork and settlement.
- LIM or property-file due diligence: If you are buying land or checking a section, allow for council information costs. As of 2025/26, Christchurch City Council charges $290 for a standard residential LIM and $390 for a fast-track LIM, while Selwyn District Council charges $300 for a residential LIM.
- Insurance and valuations: Many lenders will want insurance confirmed and may also ask for a registered valuation, especially on non-standard builds or tight-serviceability deals.
- Progress-payment funding gaps: On staged builds, make sure you know which payments come from your own funds first and which are bank drawdowns.
- Variation buffer: The New Zealand Building Code sets minimum performance standards for all building work. If plans, siteworks or specifications change during consent or construction, costs can move. A cash buffer matters, especially on custom design-and-build jobs.
Worked examples
These examples show the difference between the minimum deposit, the likely bank conversation and the real cash buffer you should aim for.
For context, our team sees Canterbury buyers compare budget-friendly townhouses in Wigram from $617,000 with family homes in Prebbleton from $849,000. If you are browsing Selwyn options, start with these new homes in Lincoln and then pressure-test the deposit numbers.
Example A: Couple with $80,000 saved buying a $650,000 Lincoln build
- Purchase price: $650,000
- 5% minimum: $32,500
- 10% target: $65,000
- Practical structure: use $65,000 as deposit and keep $15,000 as legal, valuation and variation buffer.
- Result: This is the kind of owner-occupier profile many lenders find easier to work with than a bare-minimum 5% deal.
Example B: Single first-home buyer with $40,000 saved using First Home Loan on a $580,000 Rolleston build
- Purchase price: $580,000
- 5% deposit: $29,000
- Base loan: $551,000
- First Home Loan premium: 1.2% of the loan is $6,612, which can be paid upfront or added to the loan.
- Cash left after 5% deposit: about $11,000 before legal, valuation and insurance costs.
- Result: Possible in 2026 if the buyer meets Kāinga Ora income rules, the lender accepts the build structure and servicing stacks up.
Example C: Investor with 20% deposit on a $700,000 new build
- Purchase price: $700,000
- 20% deposit: $140,000
- Loan: $560,000
- Why 20% matters: Even where the new build is exempt from the RBNZ LVR cap, a larger deposit usually gives the investor a cleaner servicing position and more room for bank policy changes.
- Result: This is often a safer planning position than trying to force an investor deal through at the lowest possible deposit.
FAQ
These are the five questions we hear most often from Christchurch and Selwyn buyers.
Can I really build a new home with 5% deposit in 2026?
Yes, sometimes. The RBNZ new-build exemption means 5% can be possible, especially for owner-occupiers, but the bank still decides whether your income, debts, contract type and property fit its policy.
Does Kāinga Ora First Home Loan still exist?
Yes. As of 2026 the scheme still exists, still works from a 5% deposit, and still runs through participating lenders, but income caps, owner-occupier rules and the 1.2% premium apply.
Can I use KiwiSaver for the full deposit?
Often you can use KiwiSaver for most or all of the financial deposit if you are eligible, but you must leave $1,000 in the account and timing can be tricky if the contract asks for money before your provider releases it.
How early should I save before approaching a builder?
Earlier than most buyers think. In practice, approach a broker or builder once you have stable income, clean conduct, and enough for at least the minimum deposit plus costs. If KiwiSaver is part of the plan, remember the three-year membership rule.
Do banks lend on land-only purchases or only land and build packages?
Both can be possible, but land-only deals are often assessed more cautiously. Many first-home buyers find a full turnkey or land-and-build package simpler because the bank can see the end value, the build contract and the timeline upfront.
