Small Business Sued at the NZ Disputes Tribunal — How to Respond to a Customer Complaint

What a Disputes Tribunal Claim Means for Your Business

A customer has filed a claim against your business with the Disputes Tribunal, and you've received a Notice of Hearing from the Ministry of Justice. The claim could be for a refund on goods or services, compensation for faulty work, or money for a breach of contract — anything up to $60,000 since the January 2026 jurisdiction increase.

The first thing to understand: this is not a lawsuit in the traditional sense. The Disputes Tribunal is informal, lawyers cannot represent you, and there's no formal written defence deadline. What matters is the hearing date on your notice. If you don't attend, the referee can proceed without you and issue a binding order based solely on the customer's evidence.

Common Claims Against Small Businesses

Customer claims at the Disputes Tribunal typically fall into a few categories:

• Faulty goods or services — the customer says what you sold or provided doesn't match what was promised, invoking the Consumer Guarantees Act 1993
• Incomplete or substandard work — a job wasn't finished, wasn't done properly, or caused additional damage
• Refund disputes — the customer asked for a refund and you declined, or you offered a repair instead
• Misrepresentation — the customer says they were told something about the product or service that turned out not to be true
• Overcharging — the final invoice exceeded what was quoted or agreed

Each category has different evidence requirements. A faulty goods claim turns on whether the product met the Consumer Guarantees Act standards at the time of sale. An overcharging dispute turns on what was quoted and what was agreed.

Your Response Options

You have four paths when responding to a customer's claim:

Dispute the claim entirely. You believe the customer has no valid complaint — the goods were fine, the work was completed to standard, or the customer caused the problem themselves. You'll present your evidence at the hearing.

Admit and settle. You agree the customer has a point. Contact them directly to negotiate a settlement before the hearing date. If you reach an agreement, the customer must formally withdraw the claim or submit the settlement to the Tribunal registry — don't assume the hearing is cancelled until you have written confirmation.

Make a counterclaim. The customer owes you money from the same transaction — unpaid invoices, damage to equipment, or costs you incurred because of something they did. File a counterclaim using the standard claim form with the CIV reference number from your notice.

Partly admit, partly dispute. You agree the customer is owed something, but not the full amount claimed. Prepare evidence showing what's reasonable — comparable quotes, industry standards, the actual cost of remediation.

Preparing Your Evidence as a Business

Referees expect chronological, documented evidence — not emotional arguments about difficult customers. Prepare:

• The original agreement — written contract, quote, email confirmation, or text messages setting out what was agreed
• Communication records — every email, text, and letter between you and the customer, in date order
• Work records — job sheets, progress photos, delivery confirmations, inspection reports
• Financial documents — invoices, receipts, payment records, refund offers
• Third-party evidence — independent assessments, supplier warranties, or manufacturer specifications

Organise everything in a numbered bundle and provide a copy to both the Tribunal and the customer before the hearing. Referees operate under an inquisitorial model — they'll ask questions and direct the conversation rather than letting the parties argue back and forth.

What Happens at the Hearing

You'll present your side directly to the referee. No lawyers, no formal legal language. The referee will ask questions, examine documents, and may challenge both parties on weak points. Hearings typically run 30 to 90 minutes for straightforward claims.

If the claim involves the Consumer Guarantees Act, the referee will focus on whether the goods or services met the statutory guarantees at the time of supply — not whether you intended to provide something substandard.

The NZ Disputes Tribunal Response Guide includes an evidence index worksheet, a hearing-day checklist, and a response decision flowchart designed for business owners who need to organise their defence quickly.

After the Decision

The referee's order is binding. If you're ordered to pay, you can negotiate an instalment arrangement with the customer. For civil-debt payment or enforcement questions, contact the Ministry of Justice Civil Collections Unit at 0800 233 222. If a rehearing ground applies, you can apply within 20 working days (free); an appeal to the District Court ($275 filing fee, also within 20 working days) is limited to procedural unfairness that prejudicially affected the outcome.

An unpaid order can be enforced through the District Court. Options include an attachment order directing an employer or Work and Income New Zealand (WINZ) to deduct regular instalments from wages or benefits, a warrant to seize property, or a charging order against real estate. Taking the hearing seriously from the start is the most practical defence.
