But at what cost has this victory come?
South Taranaki mayor Ross Dunlop says the legal battle has cost the council at least $300,000-$350,000, with support from the Ministry of Health.
Water New Zealand puts the cost at upwards of $500,000.
The New Zealand Dental Association has quite rightly called the six-year legal proceedings expensive and unnecessary, a cost to ratepayers and a cost that has also fallen on the Crown via the Attorney General.
Dunlop said they'd had a request from the local district health board to add fluoride into some extra communities in the district, and were just trying to do the right thing, "particularly for young people in our communities with challenges in oral health."
"It turned into a major legal battle, which wasn't our intention."
A lengthy, expensive fight just to do what's right.
Ratepayers and taxpayers should be outraged.
