22nd May 2015 Press release from Palmerston North City Council

Fluoride-free water now available

Palmerston North City Council is now providing a source of fluoride-free water for those residents who want it.

A centrally located tap has been installed which draws off water from the Papaioea Park bore so that water can be collected by residents who prefer not to drink water with fluoride added. The water from this tap is chlorinated.

“We know there are some residents who would like to drink non-fluoridated water and we hope this will give them an option,” Dora Luo, Council’s water asset engineer said. The installation of the tap was adopted in the 2014/15 Annual Plan Dora says.

“At the moment there are one or two issues around access, but we are working on making the whole area more user friendly,” Dora said.

The water will only be available from 6:30am to 9:00pm due to the operational hours of the bore. Water is supplied to this location from other sources in the City on other times.

The tap is installed on the eastern side of the yellow building closest to the Papaioea Park entrance on Featherston Street. It is planned to shift the tap closer to the street frontage as soon as security fencing can be erected. The tap is self-closing to minimise any unnecessary water wastage.



March 2013 – Stuff article: Mayor Jono Naylor says that fluoridation is an item on the Draft Annual Plan and the council will decide from there whether to “consult, have a referendum, have a Tribunal or just decide”.

October 2013 – $10,000 has been set aside for Beca Consultancy to review fluoridation. Beca employee, Andrew Watson, has been given the task. Mr Watson says he has worked in the area of water services for many years and was in fact working in, and somehow involved with, the Queensland Government’s decision to instigate mandatory fluoridation. Mr Watson has produced a report that will be given to the councillors after the elections.

12th July 2013 – Palmerston North District council have advised people who submitted to the Draft Annual Plan that they have “decided to provide funding for an initial independent assessment for and against fluoridation, including decision making process options that will be available to the Council.”

24th May 2013 Manawatu Standared Mayor wants ministry to review fluoridation stance

16th May 2013 Article in Manawatu Standard commenting on the push to end fluoridation in Palmerston North. Interesting that the DHB director of dental health services says they shouldn’t stop fluoridation until they can figure out how to make everyone brush their teeth twice a day. So, the whole populating has to drink a dental medication so that they can force people who don’t brush their teeth to have fluoride. It is also admitting how fluoride works from the outside of the tooth surface, not from the inside

A campaign is now underway in Palmerston North.  35 – 40 submissions were received on the topic of fluoridation by Council for the 2013 Draft annual plan. All bar two, were asking the council to stop fluoridation. The councillors appear interested in looking at how they can review this issue.
