Request for Information under the Local Government Official Information and
Meetings Act 1987 (the Act) (the LGOIMA)
Thank you for your request for information which we received via partial transfer from
the Ministry of Health on
5 December 2025.
The Ministry of Health transferred the
following questions for us to provide a response in relation to the Kāpiti Coast district:
3. Provide the full chemical composition, including chemical names,
chemical formulae, and concentrations of all fluoride compounds added
to the public water supply.
See attached the Waikanae Clearwell water testing results from water leaving the
water treatment plant along with the Sodium Silico Fluoride Safety Data Sheet
which provide the answers to this question.
5. Provide details of any chemical by-products, waste, or residues
generated during production, storage, transport, or dosing, including
their environmental and human health impacts.
Council has no chemical by-products, waste or residues. Our new fluoride dosing
system ensures there is no waste during dosing.
15. Include all corporate affiliations, financial interests, and advisory bodies
that influence decisions regarding fluoride.
Council does not have any affiliations and follows direction on fluoridation from
Taumata Arowai (the Water Regulator).
16. Provide copies of all risk assessments, environmental impact statements,
monitoring reports, and internal or external evaluations regarding
fluoride safety, dosing, and public health.
Please see the Safety Data Sheet attached.
Please note that any information provided in response to your request may be published on the Council website, with
your personal details removed.
17. Provide documentation of regulatory compliance, inspections, or audits
by government or third-party authorities.
No MAV’s (Maximum Allowable Values) have occurred relating to Fluoride, so no
regulatory compliance required.
18. Disclose any incidents, complaints, or breaches relating to fluoride
chemical safety, handling, or dosing.
No incidents, complaints or breaches have occurred.
Ngā mihi,
Sean Mallon
