ACC Review and Appeals Process

Overview

If ACC declines your claim, reduces your entitlements, or makes any other decision you disagree with, you have the right to challenge it. The process has three levels: Review → District Court Appeal → High Court Appeal. Each level has strict time limits.

Step 1: ACC Review (First Level)

Before going to court, you must have your case heard at a Review. This is an independent internal process.

Time Limit

You have 3 months from ACC's decision to apply for a review. You can apply the day you receive the decision letter.

How to Apply

1. Write to ACC asking for a review — include your claim number, the decision you disagree with, and your reasons.
2. You can use ACC's review application form (available on the ACC website).
3. Alternatively, you can email or write to ACC's review unit.

The Review Hearing

• An independent reviewer (not an ACC employee) hears your case.
• The hearing can be in person, by phone, or by video conference.
• You can represent yourself, bring a support person, or use a lawyer/advocate.
• You can submit evidence — medical reports, letters, witness statements.
• ACC also presents its case.
• The reviewer issues a written decision, usually within 4–6 weeks.

Step 2: District Court Appeal (Second Level)

If you disagree with the review decision, you can appeal to the District Court.

Time Limit

You must file your appeal within 28 days of receiving the review decision.

Process

• File a notice of appeal with the District Court (there's a prescribed form).
• The appeal is heard by a District Court Judge.
• It is a full rehearing — new evidence can be submitted.
• Many people use a lawyer or ACC advocate at this stage, but self-representation is possible.

Step 3: High Court Appeal (Third Level)

If you disagree with the District Court decision, you can appeal to the High Court, but only on a question of law — not a re-examination of the facts.

Time Limit

You must file within 28 days of the District Court's decision.

Further appeal to the Court of Appeal and Supreme Court is possible but rare — you need leave (permission) from the court.

Helpful Tips

• Keep copies of all correspondence, medical reports, and emails with ACC.
• Note all deadlines — missing a time limit can lose your right to appeal.
• Seek help early: Community Law Centres, ACC advocates, and some lawyers offer free initial advice.
• Medical evidence is key: Strong support from your GP or specialist greatly increases your chances.
• Don't give up: Many successful appeals happen at the Review stage with proper evidence.
