Official Information Act requests

The Official Information Act

The Official Information Act (OIA) is an important part of New Zealand's constitutional framework. The OIA allows New Zealanders to have access to information that enables their participation in their democracy and hold governments and Public Sector agencies to account.

The OIA allows New Zealand citizens, permanent residents, and anyone who is in New Zealand to request any official information held by government agencies - including the Ministry of Health.

The Ministry has adopted an OIA Policy that outlines its obligations.

How to request official information from the Ministry of Health

Due to the COVID-19 global pandemic response, Ministry of Health continues to experience significantly higher volumes of requests for information. This means we may take some time in responding to your request.

The Ministry can only answer requests for information that it holds. There is no requirement for the Ministry to create new information, compile information it does not hold, or to provide an opinion.

If you believe a different agency holds the information, please request the information from that agency. For example, if you are after your medical records, please contact your DHB or GP.

For information from other agencies check out the Directory of Official Information to find out what information each agency holds, and their contact details.

Requests for information from the Ministry of Health can be sent to:

Email: [email protected]

Online form

Postal address:

Ministry of Health
PO Box 5013
Wellington 6140

Requests should include:

  • your name
  • your contact details (email address or postal)
  • details of the information you want - your request should be as clear and specific as possible.

You can specify the format you want the information presented in – for example by email or by post.

How long will it take?

We will acknowledge your request as soon as practicable and are required by law to respond no later than 20 working days after we receive it.

For large requests or those requiring consultation, the Act allows for a reasonable extension to this time limit. If so, we will let you know and give you a specific due date.

We may also transfer your request, either in full or part, to another agency subject to the Act if they are better placed to respond to that part of your request. We will advise both you and the agency we have transferred your request to of this decision.

If you amend your request, the 20 working days will start from the day after this amendment has been received. If we need to clarify your request and do so within the first seven working days, the 20 working day timeframe will begin again once the clarified request is confirmed.

Withholding information

The OIA says information should be made available unless there is good reason to withhold it. We may only withhold information for specific reasons set out in the Act. If this occurs, we will let you know why.

For more information refer to sections 6, 9 and 18 of the OIA
