As noted in the table above, and on the documents themselves, some information has been
withheld under section 9(2)(a) of the Act, to protect the privacy of individuals.
In making my decision, I have considered the public interest considerations in section 9(1) of
the Act. No public interest has been identified that would be sufficient to outweigh the
reasons for withholding that information.
In addition, in the table below is a link to the Prime Minister’s Chief Science Advisor’s website
page with information relating to fluoridation: “
Fluoridation: an update on evidence”. This
webpage was last edited on 17 November 2023 and includes some information relevant to

Your request as it relates to the information on the Chief Science Advisor’s website is
declined under section 18(d) of the Act, on the basis that this information is already publicly
available.
You have the right to ask the Ombudsman to investigate and review my decision under
section 28(3) of the Act.
Yours sincerely
Cameron Burrows
