How Is Real Estate Commission Calculated in New Zealand?
Commission calculation in New Zealand is often less transparent than sellers expect. Here is exactly how it works, with the specific numbers.

The two main structures
Flat percentage: commission is calculated as a fixed percentage of the sale price. If the agreed rate is 3.5 percent and the property sells for $720,000, the commission before GST is $25,200. Add GST at 15 percent and the total is $28,980.
Tiered structure: a higher rate applies to the first portion of the sale price, and a lower rate applies to the balance. This is the most common structure in New Zealand. A typical example: 4 percent on the first $400,000, then 2 percent on the balance. On a $720,000 sale: 4% of $400,000 = $16,000, plus 2% of $320,000 = $6,400. Total commission before GST: $22,400. With GST: $25,760.

GST on commission: the step most sellers forget
Commission is quoted as a GST-exclusive figure in most agency agreements. GST at 15 percent is added on top. When comparing commission rates from different agencies, confirm whether the quoted rate is GST-inclusive or exclusive. A rate that appears competitive GST-exclusive may be similar to a competitor when GST is added.

When commission is paid
Commission is typically paid on settlement day, the day the property ownership transfers and the buyer pays the purchase price. Your lawyer deducts the commission from the settlement proceeds and pays it to the agency. You receive the net proceeds after commission, legal fees, and mortgage payout.
Commission is generally not payable if a sale falls through before settlement due to buyer default.
The specific terms of your listing agreement govern this, and legal advice may be needed if a settlement failure occurs.

What commission covers
Commission covers the agent’s time, their agency’s operational costs, and, in most cases, a contribution to the agency’s marketing platforms and buyer database. It does not always cover the direct marketing costs for your specific property. Always confirm what is included in the commission and what is charged separately.

The dollar impact across common Northland price points
For quick reference, here is what a 4% plus 2% tiered commission (4% on first $400k, 2% on balance) costs at common Northland price points: $550,000 sale: $16,000 + $3,000 = $19,000 + GST = $21,850. $720,000 sale: $16,000 + $6,400 = $22,400 + GST = $25,760. $850,000 sale: $16,000 + $9,000 = $25,000 + GST = $28,750. $1,000,000 sale: $16,000 + $12,000 = $28,000 + GST = $32,200.

Is commission negotiable?
Commission rates in New Zealand are negotiable but not always moveable. Agencies with strong market performance and active buyer databases have genuine value that justifies their standard rate. The most effective approach is to understand what you are getting for the fee rather than simply pushing for the lowest number. A well-negotiated commission reduction of $2,000 is meaningless if the agent’s lesser effort or database produces a sale price $10,000 below what a stronger agent would have achieved.
