When people picture a real estate agent getting in trouble, they picture a liar. Someone who looked a buyer in the eye and invented a number, buried a fact, faked a document. A villain.

I spent a long stretch reading New Zealand disciplinary decisions, expecting to meet that person on every page. They’re barely there. The agents who actually get disciplined, who cop the real penalties and the largest compensation orders, mostly didn’t lie about anything.

They just didn’t say.

The cases that cost agents the most cluster in one unglamorous place: a known defect in the house, something the agent was aware of and never mentioned. If you’ve owned a home in New Zealand, the words “monolithic cladding” probably already made you wince. A weathertightness risk on a place that looks perfectly fine. An exterior that quietly fails. A geotechnical report that existed, that the agent had seen, and that somehow never reached the buyer.

Not invented. Not faked. Withheld.

I keep coming back to why that is worse, for a buyer, than being lied to. A lie at least hands you something to grab. A claim you can test. A “trust me” that pricks your ear and makes you go and check. You can be suspicious of words, and most buyers are. They walk through the open home with their guard half up, listening for the wrong note.

Silence gives you nothing to listen for. Everyone is friendly. The house has been styled and aired and baked into smelling like someone’s childhood. Nobody says anything alarming, because the alarming thing is the sentence nobody says. You cannot cross-examine an omission you don’t know exists. By the time you find out it existed, you own the house.

That is the failure mode the decisions are full of. Not a scammer. A pleasant, competent agent who knew one inconvenient fact and quietly decided it wasn’t their job to raise it.

Which brings me to the most consistent thing in the whole pile, and the part that genuinely surprised me.

When these agents are called to account, they reach for the same defence almost every time. Some version of: “I was only passing on what the seller told me. I’m not a building inspector. I just relayed what I was given.”

The tribunal does not accept it. Again and again, it doesn’t accept it. The reasoning, stripped down, is that an agent in New Zealand carries their own duty to disclose what they know, or ought to know. You don’t get to launder a material defect through “the seller didn’t mention it.” And the buyer’s own obligation to do due diligence, the clause everyone points to, does not cancel the agent’s separate duty to tell. Your job to check does not erase their job to disclose.

Here is what actually stuck with me, case after case. The thing failing wasn’t honesty. It was a mental model. A striking number of these agents seem to genuinely believe they are a messenger, a pipe that information passes through. “I’m not making the claim, I’m only relaying it.” It is the most stable assumption in the whole dataset, and under New Zealand law it is simply wrong.

That is a stranger and more unsettling problem than dishonesty. A dishonest agent is a bad apple you can name and warn people about. A whole profession quietly running on an incorrect picture of what the job requires is something else. It means the harm isn’t the exception. It’s built into how the work is understood by the people doing it.

This is the part that turned my ai tool from a vague idea into something specific. If the danger isn’t a dramatic lie but a quiet, almost sincere omission, then what a buyer needs isn’t a lie detector. It’s a way to make the silence visible. To know, before they sign, what kind of thing tends to go unsaid, what an agent in their situation is actually obliged to tell them, and what it has cost other buyers when it wasn’t said.

You can’t catch a sentence that was never spoken. But you can learn which sentences tend to go missing, and start asking for them out loud.

So the villain I went looking for mostly wasn’t there. What I found instead was quieter, and somehow worse. Not people lying to buyers, but an industry that has half-convinced itself that staying quiet isn’t the same thing as letting someone get hurt.

It is. The tribunal has been saying so for years. Most buyers just never get to read it.

I'm building an ai tool to resolve the above issue, and writing up what the data behind it teaches me. More soon.
