What is a sale and purchase agreement in New Zealand real estate?

What Is a Sale and Purchase Agreement in NZ?
The sale and purchase agreement is the most important document in any New Zealand property transaction. It is the legally binding contract between buyer and seller that records everything agreed and commits both parties to the transaction. Here is what every seller needs to understand.

The standard form
Most residential property transactions in New Zealand use the ADLS/REINZ Agreement for Sale and Purchase of Real Estate. A standardised form developed jointly by the Auckland District Law Society and the Real Estate Institute of New Zealand. The core form is standardised but contains blank fields completed for each transaction, and additional conditions can be inserted by either party.
Using the standard form is not legally required, but it is the industry norm and your buyer’s lawyer will expect it. Custom agreements or significantly modified forms create complexity that can delay or complicate a transaction. The main form gets updated regularly, and your agent should always be using the most current version.

Key elements of the agreement:
The parties
The agreement identifies the vendor (seller) and the purchaser (buyer) by their legal names. Ensure your name appears exactly as it does on your property title. If the property is jointly owned, all owners must sign.

The property
The property is identified by its legal description and certificate of title number, not just the street address. Your lawyer will confirm this is correct.

The purchase price
The agreed sale price, including any adjustments for included or excluded chattels. GST treatment must be specified. Residential property is typically sold on a ‘plus GST if any’ basis, meaning GST is not applicable to a standard residential sale.

Settlement date
The date on which ownership transfers and funds are exchanged. This is agreed between buyer and seller and is typically 20 to 40 working days after the agreement becomes unconditional, though it can be longer or shorter depending on both parties’ circumstances.

Conditions
Any conditions the buyer requires to satisfy before the contract becomes unconditional. Typically finance Council LIM, and building inspection. Each condition has a specified timeframe. Conditions must be either satisfied or waived by the agreed date or the agreement can be cancelled.

Chattels schedule
The list of moveable items included in the sale. The standard agreement includes a default chattels schedule listing common items. Anything not on the default list that is included must be specifically added. Anything on the default list that is excluded must be specifically removed. This schedule is the source of many settlement disputes when not completed carefully.

Vendor warranties
The agreement contains vendor warranties, statements you make as seller about the property. The most significant is the general warranty that you are not aware of any matter that would materially affect the value of the property or the buyer’s decision to purchase that has not been disclosed. This warranty creates a legal obligation to disclose material defects.

Your obligations as seller after signing
Once the agreement is signed, you are obligated to maintain the property in the condition it was in when the contract was signed until settlement. You must not remove anything that is included in the agreement. You must complete any work agreed as a condition of sale. And you must be available to facilitate the pre-settlement inspection.

Get your lawyer involved early
Do not sign a sale and purchase agreement without your lawyer reviewing it first. Even if the agent says it is standard and urgent. Even if the buyer is applying pressure to sign quickly. A brief legal review before signing can prevent costly disputes at settlement. Your lawyer’s job at this stage is to ensure the agreement accurately reflects what was negotiated and that your interests are protected.
