Is my town fluoridated? 

The following is a list of all towns and cities in New Zealand that are, or have been, fluoridated.  If your town is not on the list, then it has never been fluoridated. See also fluoridation status by council and what are they fluoridating with? Note: In July 2022 the Director General of Health send the following councils an order to start fluoridation: Auckland (to fluoridate Onehunga and Waiuku), Hastings, Horowhenua, Kawerau, Nelson, New Plymouth, Rotorua Lakes, Tararua, Tauranga City, Waipa (for Cambridge), Waitaki, Western Bay of Plenty, Far North (for Kerikeri and Kaitaia) and Whangārei.  Councils will have between six months and over three years, depending on the circumstances, to fluoridate parts of their water supply that were not already fluoridated. See our Legislation page for more information on this. Last updated 24 May 2024.
