Information relating to this part of your request is publicly available on Manatū Hauora
website at:
www.health.govt.nz/system/files/documents/pages/binder_of_fluoridation_information_redac
ted_v5.pdf.
Further responses concerning amendments to budgeted costs of fluoridation of water
supplies (this includes revisions to any of the earlier information) that have been sent
to the Ministry of Health, up to October 30, 2023.
Manatū Hauora has identified a number of documents to be within scope of this part of your
request. However, Manatū Hauora has decided to extend the period of time available to
respond to this part of your request under section 15A of the Act, as consultations necessary
to make a decision are such that a proper response to this part of your request cannot
reasonably be made within the original time limit. You can expect copies of the remaining
documents on or before 22 December 2023
Please supply total funding directed to support local drinking water suppliers fluoridate
local water, and details of which councils received a particular funding injection.
- 2021/2022
- 2022/2023
Current proposed budget for 2023/2024 by council and in total.
There was no funding made to any of the local authorities for the 2021/22 financial year. As
for the 2022/23 financial year, Manatū Hauora paid $135,000 to the New Plymouth District
Council.
The budget for capital costs for fluoridating community water supplies is $24 mil ion over a
10-year period to the 2026/27 financial year. Please note, the total budget is not divided by
local authority. Manatū Hauora is currently working with local authorities as they develop
their funding proposals.
It is unclear from appropriations budgets how financial costs for fluoridation are
categorised. Please show/advise how financial ledgers categorise Ministry costs for
fluoridation.
Water Fluoridation appropriation financial costs are categorised as Departmental
Expenditure under the Public Health and Population Health Leadership category of the
Stewardship of the New Zealand Health System multi category appropriation. As for specific
account code categorisation, Manatū Hauora classes the disbursement of these costs as
‘outsourced services’. The local authority that receives this funding would make their own
categorisations across personnel, operating costs etc as needed. Manatū Hauora does not
keep a record of this.
It is understood that fluoridation does not completely prevent caries but that there may
be an uncertain marginal benefit to the DMFT (HNZ00030962). Please advise the
budgeted costs savings to treatment of dental caries for the public health sector from
this initiative in the 0-7 (or - 0-10) age group.
Information within scope of this part of your request is publicly available on Manatū Hauora
