Debate over fluoride flares 

Martin Mould tells councillors about the fluoride plans for Cambridge.

Public health officials have identified Waipā as a place they want to see community water fluoridation introduced this year.

And the first community cab off the rank is likely to be in Cambridge, Water Services manager Martin Mould told the Service Delivery committee this week.

But some committee members said they were furious about the plans before the community had been consulted.

“We want meaningful consultation,” said deputy mayor Liz Stolwyk.

Waipā’s water has never been fluoridated – nor debated by council in several years – but the passing of the Health (Fluoridation of Drinking Water) Act last year transferred the authority from district councils to the Ministry of Health and its public health officials.

Adding fluoride to water supplies is a measure to help prevent tooth decay – and it makes a “significant difference”, according to the Ministry of Health.

Sources have told The News, Waipā children are waiting on average three years to be seen by a dentist.

The last time any significant research was done on dental decay rates in Waipā was in 2015 and it revealed eight in 1000 Waipa children had been hospitalised for dental caries and dental caries were twice as common in Māori children than non-Māori.

The last time any significant investment in prevention of decay in Waipā children’s teeth was done 15 years ago when some dental clinics were closed and replaced by mobile dental vans.

The council has six water treatment plants and last year told The News adding fluoride would cost ratepayers $1.2 million upfront and about $60,000 a year.

Mould said the Ministry of Health, which becomes Health NZ next week, contacted all councils in December to check out their preparedness for community water fluoridation.

“This included estimated costs and timelines to install fluoride dosing capability.”

Waipā had no plans or funding to introduce fluoridation in the Long Term Plan, staff told the ministry and said it would cost $400,000 per plant.

The estimated costs for Cambridge, which would include the Karāpiro and Alpha Street plants, would be $480,000 with annual operating costs of $130,000.

Some funding would be available to support local authorities with the capital costs associating with introducing community water fluoridation.

The estimated time for implementation after receiving a directive to fluoridate water, is nine months.

“Seeing this in my agenda raised my hackles,” said Stolwyk.

Mayor Jim Mylchreest said he wanted the Ministry of Health to come and talk to the council about its plans.

“What is the evidence which is requiring fluoridation in Cambridge?

“Have we got a problem in Cambridge that needs addressing?” said Mylchreest.

Cr Roger Gordon said community water fluoridation was a divided issue in the community.

“We should do all we can to whoever is making this decision to say they need to come into the community and undergo real consultation.”

Cr Mike Pettit said ratepayers wanted council to stand up to something like Three Waters and would expect the same about water fluoridation.

If there were any public meetings needed, they would have to be well chaired because “I can see this getting reasonably hostile”.

Outgoing Director-General of Health Dr Ashley Bloomfield has told other local authorities that adding fluoride to water supplies would reduce the prevalence and severity of dental decay. There were significant opportunities for improvement as there were inequitable oral health outcomes between Māori and non-Māori, he said.
