Past Dunedin Campaigns
6th May 2018 Otago Daily Times Mosgiel lobby group fighting fluoride
19th January 2015 Otago Daily Times Fluoridation maybe in the pipeline. Fluoridation coming back on the agenda in Dunedin when councillors decide whether to extend fluoridation to Mosgiel and other outlying areas of Dunedin.
16th May 2013 Otago Daily Times Head of dental health at Otago Dental school opposes the Council lowering fluoride levels
15th May 2013 Otago Daily Times A step in the right direction – Council opts to lower fluoride levels and look into options for providing unfluoridated water.
10th May 2013 Otago Daily Times SBHB chairman questions fluoride referendum. Of course the fluoridation proponents do not want a referendum. They are scared the majority of people do not want it.
6th May 2013 Otago Daily Times Call for Poll on city fluoridation
Prof Paul Connett’s visit to Dunedin has injected momentum into the Dunedin Fluoride Free group. This year council received 34 submissions on fluoridation, more than on any other topic. A number of people spoke to their submissons including local dentist Russell McLean.
10th March 2013 Otago Daily Times Anti-fluoridation clarifciation sought.
Good 2011/2012 draft Annual Plan submissions and presentations were given but by all accounts it doesn’t look as if there is any real interest from enough of the councillors. Dunedin is the home of the Dental School and a lot of the councillors are very conservative. That doesn’t mean people should give up, as Council actually voted for a referendum there in 2008 before it was overturned at the next meeting.
18th April 2011
A new anti-fluoride group was formed after Dr Connett’s talk: Fluoride-Free Dunedin.
See their web site Fluoride Free Dunedin.
Sunday, 10th April 2011
Public meeting and presentation by world leading fluoridation expert, U.S. Prof Emeritus Paul Connett: 2pm – 4pm, at Pioneer Women’s Hall, 362 Moray Place.

3rd November 2008: Dunedin City councillors have rejected the recommendations from the Infrastructrue and Services Committee and have decided NOT to consult the people of Dunedin. They were advised by the Otago District Health Board’s Medical Officer of Health, that the Ministry of Health no longer support referenda since they lost most of the referenda that they paid for last year around Otago.
Editorial: ODT 22 Oct 2008 articles
14th October 2008 – Dunedin City Council’s Infrastructure and Services committee voted on Monday (13th October 08) to have city-wide consultation on fluoridation as part of their next draft annual plan.
This was reported in: The Otago Daily Times, The Star, and Channel 9
Over 100 people attended the Wednesday 15th Oct meeting in Mosgiel with people having to be turned away due to lack of room (see Channel 9 report).
Due to the large turnout another public meeting is to be held on the 28th of October. It is important residents from all over Dunedin attend this meeting. Public Health South will be invited again so that people can hear both sides of this issue. Dunedin City Councillors will also be invited so that people can let them know how they feel and to get answers from them. Their attendence and the venue for this meeting a still to be finalised but will be posted on this site once confirmed.
Residents are reminded to attend the Council’s Public Forum on Wednesday 22nd October. It is important that residents currently living in fluoridated areas of Dunedin let the Council know that they support the public consultation as this is still subject to a final vote at the next full Council meeting on the 3rd November.
The petition will now be presented with submissions at the Draft Annual Plan. Please contact FANNZ if you able to help collect signatures.

The City’s archives show that fluoridation was first mooted in 1958 and that fluoride was first added to Dunedin’s community water supply on 11 May 1967. The historical records also show that consultation took the form of deputations and polls leading up to the decision to introduce fluoride into the water supply.
Sodium fluorosilicate
The targeted dose is 0.75 mg/L which is in line with the 0.7 to 1.0 mg/L guidance from the Ministry of Health: https://www.health.govt.nz/our-work/preventative-health-wellness/oral-health/community-water-fluoridation.
The fluoride dose is monitored continuously with fluoride analysers at the WTPs and through weight changes at the dosing system.
An external laboratory (Eurofins) provides monthly validation testing for both WTPs.
The wastewater from our treatment plants is treated to within our consent conditions and then discharged to the outfall which is to sea. The bulk of Dunedin city wastewater is treated at Tahuna wastewater treatment plant and discharged to a 1.1km outfall line off the St Kilda coast.
No. Addition of chemicals to drinking water is not a matter that is regulated via resource consents. Dosing of fluoride in drinking water is recommended (see MoH guidance above).
Approximately 18 tonnes (varies with annual water demand) of sodium fluorosilicate are added per annum. Based on the latest tender price the cost is approximately $42,523/year.
DCC has not implemented new fluoride dosing systems for several decades. The existing systems are robust and enduring with low operating costs circa <$5000 per year.
The most recent test cost for Eurofins is $10.30 per test. For 24 samples per year this equates to $247.20.
Sodium fluorosilicate is approximately $2,330 per tonne based on the latest tender price.
Approximately 18 tonnes (varies with annual water demand) of sodium fluorosilicate are added per annum.
