Whether you’re buying a new build or an existing property affects several aspects of your first home purchase — including the house price caps and First Home Loan eligibility. Here’s what you need to know.
KiwiSaver First Home Withdrawal — Does Property Type Matter?
For the KiwiSaver first home withdrawal itself, the property type (new build vs existing) does not affect eligibility or the amount you can withdraw. The withdrawal rules are the same:
- 3 years of KiwiSaver membership
- Never previously owned property in NZ (or in same financial position)
- Purchasing a residential property in NZ
- Intending to live in the property
The distinction between new build and existing property matters more for house price caps and First Home Loan eligibility.
House Price Caps — How They Differ
House price caps are regional limits on the purchase price of a home you’re buying with assistance. The specific caps that applied to the (now closed) First Home Grant were higher for new builds than existing properties in most regions.
While the First Home Grant closed in May 2024, house price caps still apply to the First Home Loan — and new builds generally have higher caps than existing properties.
As of 2026, First Home Loan house price caps for selected regions:
| Region | Existing property | New build |
|---|---|---|
| Auckland | $875,000 | $925,000 |
| Wellington | $750,000 | $800,000 |
| Canterbury (Christchurch) | $625,000 | $700,000 |
| Rest of NZ | $575,000–$650,000 | $650,000–$750,000 |
Caps change periodically. Always confirm current limits with Kāinga Ora (kaingaora.govt.nz).
In high-cost markets like Auckland, the $50,000 higher cap for new builds can make a meaningful difference to what you can buy.
First Home Loan (5% Deposit) — New Build vs Existing
The First Home Loan (not the closed First Home Grant) allows eligible buyers to purchase with just a 5% deposit, backed by the government through Kāinga Ora. Both new builds and existing properties are eligible.
Key distinctions:
- New builds may have higher house price caps (see above)
- New builds may be easier to finance with LVR restrictions (Reserve Bank rules)
- The LVR exemption for new builds (20% deposit normally required for investment; lower for new owner-occupiers) can make new builds more accessible for first buyers
Leaky Home Risk — Existing Property Consideration
If you’re buying an existing property — especially one built 1992–2004 — leaky home risk is a significant consideration. Buildings from this era are disproportionately affected by weather-tightness issues due to construction methods used at the time.
Before buying an existing property:
- Get a thorough building inspection from a qualified inspector
- Check council records for any remediation history
- Be aware that leaky home remediation can cost $50,000–$300,000+
New builds don’t carry this specific risk (though they carry their own quality control considerations).
Off-the-Plan Purchases
Buying off-the-plan (a new build that hasn’t been built yet) introduces additional complexity:
- Settlement date is uncertain — the build may take 12–24 months or more
- KiwiSaver application timing: You cannot apply for withdrawal until you have a signed unconditional sale and purchase agreement, and you’ll need to recheck eligibility at the time of settlement (you must still meet all criteria at settlement, not just at signing)
- Risk: If the development is delayed significantly, your KiwiSaver balance and market conditions could change
Tell your KiwiSaver provider you’re purchasing off-the-plan early — they can advise on the process.
New Build Considerations for First Home Buyers
Advantages of new builds:
- Higher house price caps for government assistance
- LVR exemptions in some cases
- No leaky home risk
- New building warranties (1-year defects, 2-year weathertight, 10-year building act defects)
- Modern insulation and energy efficiency standards
Disadvantages of new builds:
- Price premium vs comparable existing homes
- Settlement date uncertainty (off-the-plan)
- Less established neighbourhoods (some developments)
- Limited negotiation on price
KiwiSaver Withdrawal Process — Same for Both
The application process for your KiwiSaver first home withdrawal is identical regardless of property type:
- Sign sale and purchase agreement (unconditional for existing; may be conditional until title/CCC for new)
- Apply to your KiwiSaver provider with the signed agreement
- Provide required documentation
- Funds transferred to solicitor’s trust account before settlement
