The appeal pathway at a glance

  1. 1 · Ask for a review of the decision

    Most MSD decisions can first be reviewed internally. You generally have a limited window from the date of the decision, so act promptly and put your request in writing.

  2. 2 · Benefits Review Committee (BRC)

    If you are not satisfied, the decision goes to a Benefits Review Committee — a panel that reconsiders the case. This is the step most appeals pass through before the Authority.

  3. 3 · Social Security Appeal Authority (NZSSAA)

    If the BRC does not resolve it, you can appeal to the NZSSAA — an independent tribunal that hears social-security appeals. Its powers and the appeal process sit in Part 7 of the Social Security Act 2018 and the Social Security Regulations 2018.

  4. 4 · High Court (points of law)

    An NZSSAA decision can be appealed further to the High Court, but generally only on a question of law.

Frequently asked questions

What is the NZSSAA?

The Social Security Appeal Authority is an independent tribunal that hears appeals against decisions made under social-security law — for example decisions about benefit entitlement, overpayments, or supplementary assistance.

How long do I have to appeal?

Time limits apply at each stage (review, Benefits Review Committee, and appeal to the Authority). They are short, so request a review as soon as you receive a decision you disagree with, and check the specific timeframe in the Social Security Act 2018 and its regulations.

Do I need a lawyer?

No. Many appellants represent themselves or are helped by a community-law centre or benefit advocate. Understanding the relevant sections of the Act and how the Authority has decided similar cases makes a big difference.

What can I appeal to the NZSSAA?

Broadly, decisions of a Benefits Review Committee and certain decisions made under the Social Security Act 2018. The Act sets out which decisions carry a right of appeal.

What happens after the NZSSAA decides?

If you disagree with the Authority on a point of law, you may be able to appeal further to the High Court.
