Text Messages, Photos, and Emails as Evidence at the NZ Disputes Tribunal

Digital Evidence Is Accepted — and Often Decisive

The Disputes Tribunal accepts digital evidence: text messages, emails, photographs, social media posts, online listings, and any other electronic communication or record. In many disputes, digital evidence is the strongest material either party has — particularly when the original agreement was made informally over text or email rather than in a written contract.

The referee can consider any evidence they find relevant, regardless of its format. The Tribunal operates informally under Section 18 of the Disputes Tribunal Act 1988 — there are no strict rules of evidence like a formal court. What matters is whether the evidence is relevant, authentic, and helps the referee determine the facts.

Presenting Text Messages

Text messages are often the clearest record of what was agreed, what was communicated, and when. A text exchange showing you offered to fix a problem, or that the claimant agreed to a price, can be decisive.

How to prepare text evidence:

1. Screenshot the full conversation thread — not isolated messages. The referee needs context, and cherry-picked messages without their surroundings look unreliable.
2. Include timestamps and contact details — the screenshots should show the date, time, and the phone number or contact name for the other party.
3. Print the screenshots — the Tribunal's paper-submission guidance calls for the original plus three full physical copies for the registry. Exchange the required evidence with the other party before the hearing. Even if you plan to show your phone screen at the hearing, printed copies are far more practical.
4. Number the pages — integrate them into your evidence bundle with a reference number (e.g., "Doc 5: Text messages, 3 Mar – 15 Mar 2026").
5. Highlight the key messages — if the thread is long, use a highlighter on the printed copy to draw the referee's attention to the critical exchanges. Don't highlight everything.

What to watch for: text messages are easy to misinterpret without tone and context. If a message could be read two ways, prepare a brief note explaining the context — what was happening that day, what the message was responding to, and what followed.

Presenting Email Evidence

Emails are usually the most organised form of digital evidence. They have built-in timestamps, sender and recipient addresses, and subject lines.

Preparation steps:

• Print the full email thread, including headers (from, to, date, subject). If the thread is long, print the relevant portion and note that the full thread is available.
• Include attachments — if an email referenced an attached quote, contract, or photo, print the attachment alongside the email.
• Organise chronologically within your evidence bundle. If the same topic spans multiple separate email threads, bring them in date order and cross-reference them in your chronology.

Email headers can help identify the sender, recipient, date, and subject. If you have both text messages and emails covering the same conversation, bring both — they can corroborate each other.

Presenting Photographs

Photos are critical in disputes involving property damage, faulty workmanship, vehicle defects, or the condition of goods. The referee needs to see what you saw.

How to make photos effective:

• Print them in colour on standard paper — don't rely on showing your phone screen at the hearing. Printed photos can be examined alongside other documents and retained by the referee.
• Preserve the original metadata — photo metadata can include the capture date and time, and location if location services were enabled. If relevant, provide accurate date and location context alongside the photo.
• Take before-and-after photos where relevant — the condition when you received goods, and the condition after the alleged damage.
• Wide shots and close-ups — include context (the whole room, the whole vehicle) as well as detail shots of the specific defect or damage.
• Don't edit the photos — cropping for focus is fine, but filters, annotations, or any modification that changes what the image shows undermines your credibility.

Social Media and Online Listings

If the dispute involves a sale (Trade Me, Facebook Marketplace) or a public statement, the original listing or post is evidence. Screenshot it with the URL visible and the date showing. Online content can be edited or deleted, so screenshot it as early as possible — ideally before you contact the other party about the dispute.

Trade Me listings are particularly useful because they include the item description, price, seller's terms, and any condition notes that were visible to the buyer at the time of purchase.

Organising Digital Evidence Into Your Bundle

Digital evidence should be integrated into your evidence bundle alongside contracts, receipts, and other documents — not treated as a separate pile. For each piece of digital evidence:

1. Assign it a document number in your evidence index
2. Note what it shows and why it's relevant
3. Reference it in your written evidence statement at the appropriate point in the chronology
4. Prepare the original plus three full physical copies for the registry, and exchange the required copy with the other party before the hearing

The NZ Disputes Tribunal Response Guide includes an evidence index template and a chronology worksheet that covers digital evidence preparation alongside traditional documents, designed for respondents organising their case for the first time.
