Making an Official Information Act request

The Official Information Act 1982 is designed to make government activities more open and transparent to the public. It has the following very important roles:

  • to make official information more freely available to the public and provide for proper access by each person to official information relating to that person;
  • to protect official information to the extent consistent with the public interest and the preservation of personal privacy; and
  • to establish procedures for the achievement of those purposes.

NZTA is committed to the principles of openness and public engagement and endeavours to make information available unless there is a good reason to withhold it. The OIA sets out a number of reasons for which information may be withheld. These reasons include preservation of personal privacy and protection of information which has been received in confidence. Where there is good reason for withholding it, information may still be released if there are overriding considerations which mean it is in the public interest to release particular information.

More information about how the OIA operates can be found on the Office of the Ombudsman website(external link)

NZTA receives a large number of requests for information under the Official Information Act (OIA).

How will we deal with your request?

We will acknowledge your request, usually within 24 hours and respond no later than 20 working days after we receive it. Sometimes for large requests or those requiring consultation we will seek an extension, the Act allows for a time limit extension. If so, we will let you know and give you a specific due date.

We may seek further information from you if we feel your request is not clear, or we may seek to refine your request if the scope is very broad.

As part of broader NZTA policy, all responses are considered for publication on our website. If your response is to be published, we will advise you as part of our response to your request.

What will our response look like?

We will endeavour to respond to your request in your preferred manner. We will respond by restating your request and answering every question asked. Any supporting documentation supplied will usually be an attachment in the fully searchable PDF format. However, supporting documentation can be provided in any format, such as excel spreadsheet,  electronic or printed form.

In some cases, we may need to arrange for you to hear or view the information, provide you with an oral briefing, release a summary of the information or provide an excerpt or particular passage from the document.

Some documents may be provided to you with certain information deleted (‘redacted’).

If we are not able to supply all the information requested or satisfy your request in full, we will inform you in our response by referring you to the specific section of the Act and explain the reason why. For more information please refer to sections 6, 9 and 18 of the Official Information Act.

What happens if I am requesting CCTV footage?

While we do our best to assist with requests for CCTV footage, depending on the system and camera location, footage may only be held for anywhere between 24 hours and several days. Due to the quality of the cameras, distance from the road and direction the camera is facing, some footage may still not be fit for purpose as the cameras are not designed to identify individual vehicles or people.
