The case that says everything
A tenant submitted a 101-page report plus 215 pages of evidence, all apparently AI-generated, claiming $40,000 in compensation from Property Brokers over allegedly unsafe drinking water. The Tenancy Tribunal awarded $80, for inconvenience related to a dryer.
That outcome required two hearings, one remote and one in person. An adjudicator had to read all 316 pages. A property manager had to respond to all 316 pages. A landlord waited for a resolution. The claimant produced the document in a fraction of the time it took anyone to deal with it. That asymmetry is the whole story.
Why the tribunal blinked
On 7 August 2026, the Tenancy Tribunal’s principal adjudicator published new guidelines explaining how AI may be used in proceedings and flagging the risks of relying on AI-generated material. They are not a ban. They restate the existing power under the Residential Tenancies Act to award costs against frivolous or vexatious claimants.
David Faulkner, general manager of property management at Property Brokers, called the move “certainly a very positive step”, while being honest about its limits. “Everything that they say is actually in the Residential Tenancies Act,” he said, adding that the prospect of paying costs is only “a small threat” against people building AI slop cases.
That modesty matters. The guidelines signal awareness and put claimants on notice, but they do not touch the structural problem. Adjudicators are required to read everything submitted. There is no procedural shortcut. Volume equals delay.
The pattern is the tell
These submissions have a signature. Faulkner told the Herald the AI-generated claims “all have the same pattern”, noting that “when you get a claim with, say, 200 pages against you, it can be quite intimidating” and that “a lot of what the AI spits out is actually also incorrect.” He has since seen claims as high as $70,000.
Industry commentary paints the same picture. Some complaints have reportedly run to 300 pages, and one background report described how a first complex case was quickly followed by several more requesting $40,000, $50,000 and $60,000 in the same format. Identical structure, identical legal framing, unmistakable origin.
Sarina Gibbon of Tenancy Advisory offered the sharpest framing, describing AI in background coverage as “an amplifier, not an equaliser”. It can help renters understand genuine rights, but it also inflates weak cases. She also noted that “more words aren’t necessarily better”, and that clear information about what went wrong beats pages of legislation and case law.
The cost lands on the responder
Background survey work reported via OneRoof found that six in 10 property managers said tenants were using AI in tribunal matters, and the same proportion said it was turning routine problems into disputes. A leaking tap can now become a five-page AI-generated complaint. Wait times were reported to have stretched from three to four weeks out to around two months, a delay that compounds losses for landlords chasing unpaid rent or damage.
Here is the point that should worry every business, not just landlords. AI has made it free to manufacture complexity. It has not made it free to respond to that complexity. A property manager spending days parsing a 200-page hallucination absorbs a real cost the claimant incurred in minutes.
The tribunal is a preview
The Tenancy Tribunal got here first because it is accessible, self-represented and high-volume, exactly the conditions that make AI claim inflation visible early. The rental bond database shows the sheer size of the landlord-tenant universe, and the 2024 annual report captures a caseload from before the surge became acute.
But the same dynamic is coming for Employment Relations Authority hearings, insurance disputes, consumer complaints, construction contract fights and franchise disagreements. Anywhere a party can generate volume for free and force the other side to answer it, the economics now favour the noise-maker.
Guidelines and a “small threat” of costs will not fix that. The deeper fix is procedural, and some observers have floated the obvious irony of the tribunal using AI itself to strip voluminous claims down to their core justification. Until dispute bodies fight fire with fire, businesses should assume the next inflated, hallucinated, expensively worded claim is already being drafted, at zero marginal cost, by someone who will never read all 316 pages themselves.
