Vendor Warranties under the ADLS Agreement – Disclosure Obligations
June 2026




The Agreement for Sale and Purchase of Real Estate published by The Law Association (formerly ADLS/REINZ) (the Agreement) remains the standard contractual framework for property transactions in New Zealand.
One of the key features of the Agreement is the vendor warranties—contractual promises given by the vendor to the purchaser about the state of the property, both at the date of the Agreement and (in some cases) at settlement of the sale.
The principle of caveat emptor (buyer beware) is a basic rule which applies to Agreements for Sale and Purchase. This means that a purchaser is generally responsible for undertaking their own due diligence investigations into the property.
However, the vendor warranties within the Agreement significantly qualify the traditional “buyer beware” principle by shifting risk to the vendor for specific matters covered by the warranties. It is therefore that vendors are aware of their disclosure obligations under the vendor warranty clauses.
The nature and timing of vendor warranties
Vendor warranties operate as statements of fact or assurances about the property. They typically apply at the date of the Agreement and at settlement (or immediately before).
If a warranty is incorrect, the purchaser may seek compensation or sue in damages, even after settlement. Warranties are not limited to matters within the vendor’s actual intention to mislead— even inadvertent non-disclosure can amount to breach.
Core vendor warranties in the ADLS Agreement
However, the safest course of action for vendors is to disclose any notices that have been received from authorities, neighbours, tenants or other parties that relate to the property so that the purchaser has a full picture at the outset.
In practice this places a significant onus on the vendor. The safe course is for vendors to disclose anything that they are aware of, including known building defects, that could spark a dispute or a claim to reduce the risk of a claim being made against the vendor by the purchaser for breach of this warranty.
There are additional warranties and legal obligations on vendors when selling unit title properties and so extra caution is required.
Practical disclosure principles
The safest approach is full and frank disclosure of any matter that could fall within a warranty. Vendors should disclose anything affecting the property, ensure disclosure is recorded in writing, and amend warranties where necessary. A purchaser’s due diligence does not automatically relieve a vendor from liability for breach unless the purchaser has actual knowledge of the issue.
When selling your property, it is important to take legal advice before you sign, particularly if you are unsure about what you should be disclosing about your property.
