How to Write an Evidence Statement for Disputes Tribunal NZ

What Counts as Evidence in the Disputes Tribunal

The Disputes Tribunal is informal compared to the District Court, but Referees still want organised, factual material — not a stack of loose papers. Evidence that works includes contracts, invoices, receipts, bank transfer records, text messages, emails, photographs, repair quotes, and expert assessments.

The common thread: everything should be something that exists independently of your testimony. A Referee weighs documented facts more heavily than verbal claims. If you say the contractor promised to finish by March and you have a text message confirming that date, bring the text message.

Building a Chronology

Start with dates. Referees expect evidence presented in chronological order — date, event, supporting document. A simple table format works:

• Date: When it happened
• Event: What happened, in one or two sentences
• Document reference: Which exhibit supports it (e.g., "Exhibit 3 — text message screenshot")

Work through the entire history of the dispute from first contact to the claim being filed. Include the moments where things went right as well as wrong — context helps the Referee understand the full picture.

How to Present Text Messages and Digital Evidence

Screenshots are the standard approach. For text messages, capture the full conversation thread with timestamps visible, not just the single message you want to highlight. Crop personal information that isn't relevant to the dispute, but keep enough context that the Referee can follow the exchange.

For emails, print the full email with headers showing the sender, recipient, date, and subject line. Cherry-picked extracts without context will raise questions.

Digital files must be in standard formats: PDF or JPEG for documents and photos, MP4 or MP3 for audio or video. The registry imposes a 5MB limit per file attachment for digital submissions. If your photos are large, resize them before submission.

All evidence needs to go to both the court registry and the other party before the hearing. Prepare the original plus three physical copies for the registry, or submit digitally if the registry accepts electronic filing for your case.

Photos as Evidence

Photographs are powerful evidence in building disputes, faulty goods claims, and property damage cases. A few rules:

• Date-stamp matters. If your phone's metadata shows when the photo was taken, keep the original file. If you've edited or cropped the image, note that.
• Context shots. Take wide-angle photos showing the location and close-ups showing the specific defect or damage. A close-up of cracked plaster means nothing without a wider shot showing which wall it's on.
• Before and after. If you have photos from before the problem occurred, they're some of the strongest evidence you can bring.

Witness Statements

Witnesses who can corroborate key facts strengthen your case. A witness attending in person (or by phone) carries more weight than a written statement, because the Referee can ask follow-up questions.

If a witness won't attend voluntarily, you can apply to the registry for a formal Summons to Witness under Rule 14 of the Disputes Tribunals Rules 1989. The summons must be served personally, and you need to offer the witness reasonable travel and subsistence expenses at the time of service.

Written statements from people who can't attend should stick to facts they personally witnessed — not opinions about who's right or wrong.

AI Tools and Evidence Preparation

The Ministry of Justice has issued guidelines on AI use in courts and tribunals. You can use AI tools to help structure a chronology or organise documents, but every fact in your submission must be accurate and verifiable. AI-generated legal citations are a known risk — if a tool invents a case reference that doesn't exist, and you submit it, that undermines your credibility with the Referee.

Submission Timeline

Get your evidence to the registry and the other party at least two weeks before the hearing date. This isn't a hard statutory deadline for the Disputes Tribunal (unlike more formal courts), but late evidence may be excluded or given less weight. It also gives the other party time to respond, which the Referee expects.

For a structured evidence index template and step-by-step preparation worksheets, the NZ Disputes Tribunal Response Guide walks through the entire process from receiving your papers to the hearing itself.
