Commission-only real estate is a boom-time model stranded in a bust

A model built for a boom

New Zealand real estate agents are almost universally paid on commission, a structure that prints money in a rising market and pays close to nothing in a stalled one. That trade-off is now on brutal display. Cotality property economist Kelvin Davidson has called the current slump the longest and deepest recorded in at least 30 or 40 years, with real values more than 30% below their late-2021 peak.

For agents, though, the headline that matters is not price, it is volume. In July 2026, 6,090 residential properties sold, down 10% on a year earlier. Cotality logged 6,935 total deals, down 6.4% and the seventh straight monthly decline. Median days to sell stretched to 50, the fifth slowest July on record since 1992, while inventory climbed 9.3% to 33,252 properties. More stock, sitting longer, converting slower.

The maths on a single sale

A typical commission structure, per government-backed consumer information, runs 3% on the first $400,000 and 2% on the balance plus a roughly $500 admin fee. On a $760,000 median sale that is about $19,700 gross, before the agency takes its cut. Handsome, when an agent is closing several a month. In a market where completions have collapsed and deals routinely fall over, the agent who did the work earns nothing when it does.

The standoff is structural. REINZ chief corporate affairs officer Trey Sarten describes an infinite loop: “Buyers having more time and choice leads to longer market time, inventory builds, vendors resist price cuts, creating a stand-off over who blinks first.” Infometrics principal economist Brad Olsen notes sales activity has slipped for five months while prices move sideways, as sellers hold out for prices the market won’t pay. Meanwhile 13.1% of homes resold in the June quarter went for less than the owner paid, the highest share since 2012, with a typical loss of $60,000.

The cull is the point

Auckland agent Diego Traglia has worked the full cycle. His auction success rate went from 92% in November 2021 to around 8% in 2022, open-home numbers falling from double digits to “one or two groups.” His verdict is counterintuitive: “I actually enjoy operating in markets like this, because my market share tends to increase. Tough markets expose the difference between average agents and those who have the discipline, systems and skills to perform regardless of conditions.” Brooke Gibson of Found puts it plainly: “When we’ve had such a high, anyone’s become an agent and can do well.” The boom bloated the agent workforce. The downturn is thinning it, and that is the market doing its job.

The ecosystem behind the agent

Agents are only the visible tip. Mortgage brokers, conveyancers, photographers, stylists and stagers all feed on transaction throughput. A market where prices are flat but volumes are down 10% can hurt these businesses more than one where prices fall hard but deals keep moving, because volume is the input, not price. Tony Alexander’s survey found a net 41% of agents seeing falling prices and 51% reporting buyers worried about interest rates. The NZHL Property Report showed a net 43% calling it a buyer’s market, a position held for two and a half years, and a net 49% reporting fewer investors. First-home buyers hit a record 29% market share in July, but they cannot fill the hole left by absent investors.

Geography still saves some

The pain is uneven. REINZ data has Canterbury’s median at $710,000, up 5.2% year-on-year, with West Coast up 12.9%, while the average national home sits at $898,799, down 1.3% since the start of the year. The same commission-only model punishing Auckland and Wellington agents still works reasonably in Southland and Canterbury.

Australia’s turn

Now the warning travels across the Tasman. Australian prices are down 0.7% in July and 1.9% over the quarter, and their agents are venting online. Macrobusiness chief economist Leith van Onselen is blunt: “New Zealand is certainly a warning for Australia. The belief that home values always rise … has been shattered.” Infometrics managing director Gareth Kiernan tips real NZ prices to bottom out around mid-2027. For any service business built on churn, the lesson from this cycle is the same one Traglia learned running uphill with a 20kg backpack. When the tide goes out, you find out who was actually built for the work, and the commission model does the sorting whether the workforce likes it or not.
