Response to your request for official information

Thank you for your request under the Official Information Act 1982 (the Act) received by the
Ministry of Health – Manatū Hauora (the Ministry) as a transfer from the Office of the Minister of
Health, Hon Simeon Brown on 2 February 2026. You requested:

Any analysis of how monetary, welfare, or housing policy affects health system demand
— or confirmation none exists. Risk assessments conducted prior to the 2024-2025
health funding decisions.

The Ministry has identified 20 documents in scope of your request. These are summarised
below in Appendix 1 and copies have been released to you with some information withheld
under section 9 of the Act. Where information is withheld under section 9 of the Act, I have
considered the public interest in the release of this information and do not consider that it
outweighs the need to withhold it in this case.

Health NZ's demand forecasting methodology, including which demand drivers are
excluded.

Any mechanism by which health costs of other portfolios' decisions are fed back to
relevant Ministers.

The Ministry has identified two documents in scope of this part of your request, please refer to
Documents 14 and 15. Further information in scope of this part of your request can be found at
the following links:

information-release.
•  www.health.govt.nz/information-releases/budget-2024-information-release.

The Treasury may also hold further information of relevance to your request:
[email address].

If you wish to discuss any aspect of your request with us, including this decision, please feel
free to contact the OIA Services Team on: [email address].

Under section 28(3) of the Act, you have the right to ask the Ombudsman to review any
decisions made under this request. The Ombudsman may be contacted by email at:
[email address] or by calling 0800 802 602.

Please note that this response, with your personal details removed, may be published on the
