Tçnâ koe,

 

Thank you for your email. 

 

Under the Official Information Act (OIA), agencies are required to respond
to requests for official information as soon as reasonably practicable and
no later than 20 working days after receiving them.

If your request is for data that Health NZ holds, have you checked
[1]Lighthouse first to see if the data you are seeking is already
published?

 

Lighthouse is a searchable catalogue that makes a range of data and
analytics products available to New Zealanders to enable easier, faster
access to insights about health services.

 

You can find further information about how OIA timeframes are calculated,
including the Ombudsman’s OIA calculator, at the link below:
[2]Official information calculators | Ombudsman New Zealand

 

We will provide a response to your request in line with the statutory
timeframes set out in the OIA.

We appreciate your understanding and patience during this time.

 

Ngâ mihi,
Health NZ | Te Whatu Ora

Kia ora B White,
 
Thank you for your request of 19 March 2026 for the following information:
 

I am interested in the changes made to the Immunisation Handbook made in
March 2026.
Please supply all information leading to the changes made. This may
include:
- scientific evidence and analysis
- information supplied by vaccine manufacturers
- financial analysis
- briefings, presentations, notes
- decision documentation
- various other information

 
This correspondence is to advise you that we have transferred your
request, in part, to the Immunisation Advisory Centre at the University of
Auckland (IMAC). This is because some of the information to which your
request relates, namely any meeting minutes about changes to the
Immunisation Handbook, is more closely connected to the functions of IMAC.
In these circumstances, we are required by section 14 of the Official
Information Act to transfer your request.
 
You should expect to hear from IMAC in due course about that part of your
request. If you need to get in touch with IMAC, you can contact them at
[email address].
 
If you are not happy with this decision, you have the right to make a
complaint to the Ombudsman. Information about how to do this is available
at http://www.ombudsman.parliament.nz or by phoning 0800 802 602.
If you have any queries related to this request, please do not hesitate to
get in touch.

Dear requester,
I refer to your Official Information Act request to Health New Zealand,
which was transferred in part to the University of Auckland on 9 April
2026:
I am interested in the changes made to the Immunisation Handbook made in
March 2026.

Please supply all information leading to the changes made. This may
include:
- scientific evidence and analysis
- information supplied by vaccine manufacturers
- financial analysis
- briefings, presentations, notes
- decision documentation
- various other information

The part transferred to the University of Auckland is highlighted above;
the "decision documentation" leading to changes made to the Immunisation
Handbook in March 2026. As consultations necessary to make a decision on
your request are such that a response cannot reasonably be given within
the original time limit, the University has extended the time limit for
your request by 20 working days under section 15A(1)(b) of the OIA.

The new maximum time limit for the University’s response is 8 June 2026;
we will respond to your request as soon as reasonably practicable.
You have the right to make a complaint to an Ombudsman if you are
dissatisfied with this extension.
Yours sincerely, 

Landon Watt
Legal Advisor
Office of the Vice-Chancellor
