Discovering major defects in a property just before settlement is one of the most stressful situations a homeowner or buyer can face in New Zealand. The good news is that you do have options — but acting quickly and getting the right professional advice is absolutely critical. Whether the defects were flagged in a pre-purchase building inspection or spotted during a final walkthrough, understanding your rights and next steps can save you thousands of dollars and a great deal of heartache.
What Counts as a Major Defect?
Not every imperfection is a major defect. In the context of a pre-settlement building inspection, a major defect is generally one that:
- Affects the structural integrity of the building (e.g. foundation movement, rotting framing, earthquake damage)
- Poses a health or safety risk to occupants
- Involves significant water ingress or weathertightness failure
- Requires substantial remediation work costing thousands of dollars
- Was not disclosed by the vendor prior to sale
Minor cosmetic issues — scuffed paint, a dripping tap, or a stiff door — are unlikely to give you grounds to renegotiate or cancel a sale. A qualified building inspector can help you distinguish between the two.
The Role of a Pre-Settlement Inspection
In New Zealand, most sale and purchase agreements allow the buyer to carry out a pre-settlement inspection (sometimes called a final inspection) shortly before the settlement date. This is your chance to confirm the property is in the same condition as when you agreed to buy it — not to re-inspect for new defects you could have found earlier.
If you haven't already had a pre-purchase building inspection done by a qualified inspector, this is the most important step you can take before committing to any property. A thorough inspection report gives you documented evidence of the property's condition, which is invaluable if disputes arise. You can find experienced local building inspectors on tradedirectory.co.nz.
What Are Your Options When Major Defects Are Found?
If a major defect is discovered just before settlement, you generally have several avenues available, depending on your sale and purchase agreement and the nature of the defect:
1. Negotiate a Price Reduction
The most common outcome is negotiating a reduction in the purchase price to reflect the cost of remediation. You'll need written quotes from qualified tradespeople to support your position.
2. Request the Vendor Remediate Before Settlement
You may be able to ask the vendor to fix the defect before settlement takes place. Be cautious here — ensure any repair work is done to an acceptable standard and re-inspected before you proceed.
3. Delay Settlement
Both parties can agree to extend the settlement date to allow time for repairs or further investigation. This requires agreement from both sides and should be documented in writing.
4. Cancel the Agreement
In some circumstances — particularly if the defect was not disclosed and is serious enough — you may have grounds to cancel the agreement and recover your deposit. This is a significant legal step and you must seek legal advice immediately.
5. Proceed and Pursue a Claim Later
In some cases, buyers proceed with settlement and later pursue a claim — for example under the Contract and Commercial Law Act or other legal avenues — or through the courts if the vendor misrepresented the property's condition. This path can be costly and uncertain.
Important: Your rights depend heavily on the exact wording of your sale and purchase agreement. Always consult a property lawyer before taking any action.
Building Code and Compliance Considerations
Some defects may also raise NZ Building Code compliance issues. For example, unconsented work, weathertightness failures covered under Clause E2 (External Moisture), or structural concerns under NZS 3604 (the timber-framed buildings standard) can have serious implications for insurance and future resale. MBIE Building Performance provides guidance on what work requires a building consent and what falls under Schedule 1 exemptions — though you should always confirm with your local council.
If unconsented building work is discovered, the buyer may inherit the liability for bringing that work up to code. This is another reason why a thorough pre-purchase inspection is so valuable.
Weathertightness and Leaky Building Issues
New Zealand has a well-documented history of leaky building problems, particularly in homes built between the late 1980s and early 2000s. If your pre-settlement inspection reveals signs of water ingress, rotting timber, or failed cladding systems, treat this as a serious red flag. Remediation costs for weathertightness failures can run into the hundreds of thousands of dollars. BRANZ has extensive research and guidance on weathertightness that can help you understand the scope of the problem.
Healthy Homes and Rental Properties
If you're purchasing a property to rent out, be aware that major defects may also affect your ability to comply with the Healthy Homes Standards. Requirements around insulation, heating, ventilation, moisture, and drainage are mandatory for rental properties. Tenancy Services has full details on what landlords must provide.
When to Call a Professional
You should engage professionals immediately if major defects are found before settlement:
- Building inspector: To document defects thoroughly and provide an expert opinion on severity and likely remediation costs
- Property lawyer: To advise on your legal rights under the sale and purchase agreement before you make any decisions
- Structural engineer or specialist tradesperson: To assess specific issues such as foundation movement, structural framing, or weathertightness failures and provide remediation quotes
- Your real estate agent: To facilitate communication with the vendor's agent, though remember their primary duty is to the vendor
Don't try to handle a major defect dispute on your own — the stakes are too high. A qualified building inspector and a good property lawyer working together give you the best chance of a fair outcome.
