Understanding Sale & Purchase Agreements in NZ
When buying a home in New Zealand, one of the most important documents you’ll encounter is the Sale & Purchase Agreement (S&P Agreement). This is the legally binding contract that sets out the terms and conditions of your property purchase.
For first-home buyers, it can feel overwhelming — but understanding how it works is essential to protecting yourself and making confident decisions.
What Is a Sale & Purchase Agreement?
A Sale & Purchase Agreement is the contract between the buyer and seller that outlines:
The agreed purchase price
The deposit amount
The settlement date
Any conditions that must be met
Once both parties sign the agreement, it becomes legally binding — so it’s important to understand what you’re agreeing to before signing.

Conditional vs Unconditional Agreements
Most S&P Agreements fall into one of two categories:
Conditional Agreement
This means the purchase depends on certain conditions being met. Common conditions include:
Finance approval
Building inspection
LIM report review
Solicitor’s approval
If these conditions are not satisfied within the agreed timeframe, you can usually withdraw from the agreement without penalty.

Unconditional Agreement
Once all conditions are satisfied (or if there were none to begin with), the agreement becomes unconditional.
At this point:
The contract is fully binding
You are committed to completing the purchase
Your deposit is at risk if you fail to settle
This is a critical milestone — and one you should only reach when everything has been carefully checked.
Deposit and Settlement
The S&P Agreement will specify:
The deposit (often 10% of the purchase price)
The settlement date, when ownership transfers to you
The deposit is usually paid when the agreement becomes unconditional and is held in a trust account until settlement.
On settlement day, the remaining balance is paid, and you receive the keys to your new home.
Why Legal Advice Is Essential
A Sale & Purchase Agreement is a legal contract, and small details can have significant consequences.
A property lawyer will:
Review the agreement before you sign
Explain any risks or unusual clauses
Ensure your conditions are correctly included
Guide you through the process to settlement
Skipping legal advice is one of the biggest risks first-home buyers can take.

Common Mistakes to Avoid
Signing without fully understanding the conditions
Not including a finance or building inspection clause

Assuming you can “change your mind later”
Once signed, your options are limited — so it’s important to get it right upfront.
