The Rotorua District Council has voted to hold a referendum to determine residents' views on whether the district's water supplies should be fluoridated.
The decision was taken this morning at a meeting of the council's Strategy, Policy & Finance Committee.
In a close vote the committee resolved to support a referendum on the fluoride issue and to make the referendum result binding on the council.
This morning's vote was initially tied at 5-5 before being carried 6-5 on the casting vote of committee chairwoman, Merepeka Raukawa-Tait.
Elected members supporting the referendum were councillors Raukawa-Tait, Mike McVicker, Tania Tapsell, Deputy Mayor Dave Donaldson and Mayor Steve Chadwick.
