Official Information Act requests

The Official Information Act allows New Zealanders to have access to official information held by governments and government agencies.

    What the Official Information Act (OIA) is

    We strive to be fair and open. We're committed to making information available under the principles of the OIA unless there's a good reason to withhold it.

    The Official Information Act 1982 (OIA) allows you to make a request for official information held by New Zealand government agencies, including ACC. This includes:

    • citizens
    • permanent residents
    • visitors to New Zealand
    • body corporates registered or with a place of business in New Zealand.

    Official Information Act 1982

    Examples of information we hold

    • Internal policies and processes (e.g. Promapp, team process documents)
    • Claims data
    • Contracts
    • Information about companies
    • The reasons for any decisions that have been made about a person

    Questions that require ACC to form an opinion or provide an explanation are not requests under the OIA. Any questions relating to the management of an individual's claim are better managed by their recovery partner.

    Before you make a request

    Before making a request please check our other sources of information. You may find the information you require is already available in our Resources section where we are publishing responses to OIAs.

    How to make a request

    If you cannot find the information you're looking for in our published responses, email our OIA Services team.


    What to include in your email

    When you email us, please include:

    • your name
    • contact address (email or postal)
    • contact phone number
    • details of the information you want - this needs to be as clear and specific as you can make it. We may ask you for more details.

    You can also tell us if you are happy to receive the information in an alternative form, for example, oral briefing, viewing or summary.

    How long your request will take

    We'll acknowledge that we've received your request. We're required under the OIA to give you our decision on your request as soon as possible, and no later than 20 working days after we receive your request.

    If we need more time to make our decision on your request, for example, if you're requesting a lot of information, we'll let you know and give you an idea of how long it will take.

    Costs for making a request 

    Requesting official information is free, but we can charge a reasonable amount if it will take a lot of work to supply the information requested. We'll discuss this with you if we determine that we need to do this.

    Withholding information under the OIA

    Under the OIA, information should be made available unless there is a good reason to withhold it. We may only withhold information for specific reasons set out in the Act. If this happens, we'll let you know why.

    Refer to sections 6, 9 and 18 of the OIA

    Sort out a problem with a request

    If you're not happy with our response, email us to see if we can resolve the problem.


    You can also make a complaint to the Office of the Ombudsman if you:

    • have concerns regarding the decision we made on your request
    • are unhappy about the way your request was treated or processed.

    Concerns can relate to:

    • withholding of information
    • extending the timeframe to respond to you
    • any charges for providing the information you've requested
    • delays in providing you with a decision or the information
    • your request being transferred.

    The Office of the Ombudsman can investigate and review our decision and may make a recommendation to us if it's considered appropriate.
