Response to your request for official information 
Thank you for your requests under the Official Information Act 1982 (the Act) to Manatū 
Hauora (the Ministry of Health) on 29 September 2022 and 4 October 2022 for information 
regarding water fluoridation in Whanganui. Each part of your request is responded to below. 
1. How does this direction take place?
2. What is needed to start the process?

To commence the process of considering water supplies for a potential direction to 
fluoridate, the Director-General of Health (the Director-General) notifies a local authority that 
water supplies under its control are being actively considered for a potential direction to 
fluoridate. 
The Director-General is required, under section 116 of the Health Act 1956, to invite written 
comment from the local authority on: 
• the estimated financial costs of adding fluoride to the drinking water, including any
additional costs of ongoing management and monitoring
• the date by which the local authority would be able to comply with a direction.
The Director-General must give the local authority at least 40 working days to provide 
comments. When deciding whether to make a direction to fluoridate, the Director-General is 
required to consider: 
• the comments of the local authority
• scientific evidence on the effectiveness of adding fluoride to drinking water in
reducing the prevalence and severity of dental decay
• whether the benefits of adding fluoride to drinking water outweigh the costs
• advice from the Director of Public Health.
After issuing a direction, the Director-General must publish the direction and reasons for the 
decision. 

3. Please provide a copy of the process 
 
The process is described in section 116 of the Health Act, which can be found at:  
Health Act 1956 No 65 (as at 01 July 2022), Public Act Part 5A Fluoridation of drinking water 
– New Zealand Legislation. 
 
4. What can I do as an individual? 
 
Decision-making to direct community water fluoridation sits with the Director-General and 
follows the process outlined in my reply to questions 1 and 2.  
 
5. What are the responsibilities of my local Council to be putting fluoride in the drinking 
water? 

 
Local authorities do not need to wait for a direction from the Director-General to start 
fluoridating water supplies in their area. However, if they receive a direction, they must 
implement fluoridation by the date set in the direction. 
 
From July 2024, responsibility for implementing directions will sit with the new water service 
entities, being established under the Three Waters Reform. 
 
6. Please provide a copy of any and all communications from MoH to the Whanganui 
Council relating to adding fluoride to the water (since 2018). 

I have identified five documents within scope of this part of your request. Al  documents are 
itemised in Appendix 1 and copies of the documents are enclosed. Where information is 
withheld under section 9 of the Act, I have considered the countervailing public interest in 
release in making this decision and consider that it does not outweigh the need to withhold 
at this time. 
 
7. Can the Director-General please direct Whanganui District Council to add fluoride to 
the drinking water? 

 
I note your support of community water fluoridation and your interest in the Whanganui water 
supply being fluoridated.  
 
You’ve asked about the possibility of a future direction from the Director-General of Health to 
Whanganui District Council to fluoridate the Whanganui water supply. It is likely that further 
directions wil  be considered by the Director-General within the next year. Manatū Hauora is 
currently working through a process to prioritise the remaining local authorities and water 
supplies to be actively considered by the Director-General for potential directions to 
fluoridate. 
 
I trust this information fulfils your request. 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.

Implementation 
The Ministry of Health (the Ministry) intends to facilitate swift transition to the new 
fluoridation decision-making process, and anticipates that the Director-General of 
Health could commence issuing directions from mid-2022 onwards. Implementation will 
be phased over time and there will be some funding available to support local 
authorities with the costs of fluoridation-related capital works. 
The Ministry is working through implementation details and expects to be able to 
provide further information to you in the next month. 
The Ministry acknowledges the significance of the Government’s Three Waters Reform 
programme on local authorities, including the recent announcement of the creation of 
the new water service entities. The Ministry of Health is working closely with the 
Department of Internal Affairs to ensure that implementation planning aligns with the 
reform programme and factors in current service delivery pressures across the water 
ACT 1982
services sector.  
Resources for your communities 
You may receive queries from your communities about community water fluoridation 
now that the new legislation has been passed. We encourage you to refer members of 
the public or interested groups to the resources below. They reflect the position of the 
Ministry of Health, World Health Organization, and Centres for Disease Control and 
INFORMATION 
Prevention that community water fluoridation is a safe, effective and affordable public 
health measure to improve the oral health of communities. 
https://www.fluoridefacts.govt.nz/ 
https://www.pmcsa.ac.nz/topics/fluoridation-an-update-on-evidence/ 
We look forward to working with you to implement these new changes that will have an 
important health impact on the communities you serve. We will be in touch again 
shortly.

Community water fluoridation  
Only around half of all New Zealanders receive fluoridated drinking water. Until now, it’s been up 
to local authorities (councils) to make decisions around fluoridating their water supplies. The 
Director-General of Health now has the authority to decide if community drinking water supplies 
should be fluoridated.  

What is water fluoridation? 
Fluoride already exists in water. Water fluoridation is when the natural level of fluoride in the 
water supply is topped up to between 0.7 ppm and 1.0 ppm. This is the ideal amount for giving 
protection against tooth decay. This is recommended by many national and international health 
ACT 1982
bodies, including the World Health Organization.  
The Ministry of Health recommends water fluoridation as a safe and effective way to prevent and 
reduce tooth decay for everyone. The levels of fluoride in water are carefully monitored. 
Is it safe? 
The role of fluoride in water has been examined around the world – including in New Zealand – 
over the last 60 years. There is strong evidence that there are no adverse effects of any 
INFORMATION 
significance from fluoridation at the levels used in New Zealand, and that it is beneficial to New 
Zealanders of all ages. This is especially true for our most vulnerable communities 
Is it effective? 
Fluoride in water like a constant repair kit. It neutralises the effect of acids that cause decay and 
helps to repair damage before it becomes permanent. 
The most recent New Zealand Oral Health Survey (2009) shows that children and adolescents 
have 40 percent less tooth decay over their lifetime if they live in areas with fluoridated water. 
The government estimates that introducing community water fluoridation to all public drinking 
water supplies would result in net savings of more than $600 million over 20 years - mostly to 
consumers, and some to government?  
How will decisions about community water fluoridation be made? 
The new legislation allows the Director-General to make decisions about fluoridating public water 
supplies only. They cannot direct the fluoridation of privately-owned water supplies. 
Before issuing a direction to fluoridate a water supply, the Director-General must invite the 
RELEASED UNDER THE OFFICIAL 
affected local authority to give information in writing on the estimated cost and timing for 
introducing fluoridation.  
The new legislation requires the Director-General of Health to consider the scientific evidence of 
the effectiveness of fluoridation in reducing dental decay, and whether the benefits outweigh the 
financial costs. They must consider the oral health status (or likely oral health status) of the local 
community, the size of the water supply and how much it’s likely to cost to introduce fluoridation. 
The Director-General of Health is required under the new legislation to seek advice from the 
Director of Public Health before issuing a direction. They may also consider other factors or 



Document 1c
views. The new legislation does not require local authorities to consult with their communities on 
decisions around fluoridating their water supplies.  
Local authorities that are currently fluoridating drinking water supplies must continue to do so. 
When will the Director-General of Health start issuing directions? 
We expect the Director-General of Health could start issuing directions regarding some 
community water supplies from mid-2022. It is expected that implementation wil  be phased over 
time. The Ministry wil  be engaging further with local authorities about implementation in late 
2021 and early 2022.  
The Director-General of Health wil  ensure when providing a date by which the local authority 
must comply with a direction, that it is reasonably practical. In instances of non-compliance, the 
Director-General of Health may take action to hold local authorities to account. See sections 116
ACT 1982
and 116J of the new legislation for more information.  
Do local authorities need to wait for a direction to start fluoridating? 
No. Local authorities may wish to consider whether to fluoridate water supplies in the absence of 
the Director-General of Health issuing directions.  
Who will pay for fluoridation? 
INFORMATION 
Some funding wil  be available to support local authorities with the capital costs of fluoridation. 
The operational costs of fluoridation wil  remain with local authorities. 
Who will ensure my water is safe to drink? 
Local authorities and water suppliers wil  still be responsible for providing safe drinking water to 
their communities and need to meet water safety regulations. Water suppliers are required to 
meet the Drinking water standards for New Zealand, which set maximum acceptable values for a 
range of substances and organisms, including for fluoride.  
How does the new legislation support equity? 
Some communities and population groups in Aotearoa have worse oral health outcomes than 
others. New Zealand stil  has high rates of preventable tooth decay, particularly among Māori 
and Pacific children and adults, and those in vulnerable communities. 
The benefits of community water fluoridation are broadly spread, but are greater for Māori, 
Pacific and those living in deprived communities. 
Extending community water fluoridation aligns with the Treaty of Waitangi principles of equity 
and active protection. Te Ao Mārama (the Māori Dental Ass
RELEASED UNDER THE OFFICIAL  ociation) and the Pasifika Dental 
Association support community water fluoridation.

we still have high rates of preventable tooth decay, particularly amongst Māori and 
Pacific people, and people living in deprived communities. Evidence shows that 
community water fluoridation both improves the oral health of everyone and also has a 
proportionately larger benefit for these groups. 
Thank you for your co-operation as we work together to improve the oral health of the 
communities we each serve.
