Breach of Contract at the NZ Disputes Tribunal — Faulty Workmanship and Contract Claims

How Breach of Contract Claims Work at the Disputes Tribunal

Breach of contract is one of the most common claim types at the New Zealand Disputes Tribunal. Someone says you didn't hold up your end of an agreement — didn't finish the work, didn't deliver what was promised, or didn't pay what you owed. The Tribunal can hear these claims for amounts up to $60,000 (since January 2026).

The legal framework includes the Contract and Commercial Law Act 2017 (CCLA). A contract claim generally alleges that a party failed to perform an agreed obligation. The Disputes Tribunal can make orders within its statutory powers, including monetary or work orders; the appropriate remedy depends on the agreement, the alleged breach, and the facts.

What the Disputes Tribunal referee will want to establish: Was there a contract? What were its terms? Did you breach those terms? And if so, what's the appropriate remedy?

Responding to a Faulty Workmanship Claim

If you're a tradesperson, builder, or service provider facing a faulty workmanship claim, the claimant is saying your work didn't meet the agreed standard or wasn't completed. The referee will look at:

• What was agreed — the written contract, quote, emails, or verbal agreement about the scope and standard of work
• What was delivered — the actual state of the work, supported by photos, inspection reports, or expert assessments
• Whether the gap amounts to a breach — minor imperfections may not constitute a breach if the work substantially complied with the agreement
• The claimant's contribution — did they change the scope mid-project, fail to provide access, or refuse reasonable remediation offers?

If the claimant hired another tradesperson to fix your work, their claim will typically be for the cost of remediation plus any consequential losses (like temporary accommodation if the work made a room unusable). The referee won't award speculative or emotional damages.

Building Your Defence

Your strongest evidence is documentation showing what was actually agreed and what you actually delivered. Prepare:

1. The contract or agreement — written quotes accepted by email, text confirmations, or a formal contract. If it was verbal, note the circumstances and any witnesses
2. Progress records — dated photos of the work at each stage, job sheets, site diaries
3. Communication trail — every email, text, and phone note between you and the claimant, in chronological order
4. Variation records — if the claimant changed the scope mid-project, show the requests and any cost implications you communicated
5. Remediation offers — if you offered to fix the problem and the claimant refused, that's relevant to whether the claim amount is reasonable
6. Independent evidence — a report from another qualified tradesperson, manufacturer specifications, or building standards that support your work quality

Common Defences to Contract Claims

Several defences come up regularly at the Disputes Tribunal:

Substantial performance. You completed the work to a reasonable standard with only minor defects. The claimant may be entitled to the cost of fixing those defects, not the full contract price.

Claimant's own breach. The claimant didn't pay progress invoices, didn't provide access, or changed the scope without agreeing to additional costs. Under the CCLA, a party who has themselves breached may have a reduced claim.

Mitigation failure. The claimant let the problem get worse instead of taking reasonable steps to prevent further damage. A leaking pipe reported six months late and a flooded house is partly on the homeowner.

No contract existed. The claimant assumed you'd do work you never agreed to. Without a clear agreement on scope and price, there's no contract to breach.

Time limitation. If the claim concerns older events, check the applicable limitation period and when it started before relying on this defence.

What to Expect at the Hearing

The referee operates under an inquisitorial model — they'll ask direct questions rather than letting the parties argue. Bring your documents organised in a numbered bundle and be prepared to explain the timeline clearly. The referee may ask you to respond to specific allegations in the claim form, so read it carefully before the hearing.

If both sides have genuine grievances, a counterclaim might be appropriate — if the claimant owes you money for unpaid invoices on the same project, file it using the standard claim form with the CIV reference number from your notice.
