ACC Independent Review – How to Request a Review of Your Claim or Levy (ACC33)

Apply for a Review of an ACC Decision

If you disagree with a decision ACC has made about your claim, you can apply for a formal, independent review. To do this, you’ll need to complete and submit the ACC33 form (Application for Review).

What Happens When You Apply for a Review?

Once you submit your ACC33 form:

  • We will try to resolve the issue with you early in the process.

  • If no agreement is reached, an independent reviewer (not employed by ACC) will be assigned.

  • The reviewer will organise a review hearing, which may be held in person, online, or over the phone.

During the hearing, the reviewer considers:

  • All the information related to your case

  • Relevant ACC legislation

  • Written submissions from both you and ACC

After the hearing, the reviewer will issue a decision. They may rule in your favour or in favour of ACC.

Other Options Before Applying

If a formal review doesn’t feel right for your situation, you may wish to consider these alternatives:

These options may help resolve your concerns without a formal review.

How to Complete the ACC33 Form

You need to complete a separate form for each review you want to apply for.

What You’ll Need:

  • Details of the ACC decision you're reviewing

  • Your reasons for disputing the decision

  • Any supporting information you want to include

Completing the form takes about 10 minutes, depending on how much detail you provide.

Note: This online form cannot be saved, so we recommend having all your information ready before you start.

Time Limits for Review Applications

You must apply for a review within 3 months of the date on your ACC decision letter.

We may accept late applications in some situations — for example, if something outside your control stopped you from applying in time. You can explain your reason in the form.

Important: We can't extend the deadline for:

  • Levy-related reviews

  • Applications where the applicant is an employer

Alternative dispute resolution
