NZ First's Winston Peters is determined to give Kiwis the right to choose as part of a new bill.
The Party has introduced a member's bill that aims to repeal a 2021 fluoridation law - requiring councils to hold a referendum.
It would look into the law giving the Director-General of Health authority to mandate having fluoride in local water supplies.
Peters says people have had a right to vote on these matters for decades - and he hopes to re-instate that right.
"We're saying - give people back the democracy they enjoyed all those decades and let them decide. They're the ones who have a right in regards to what they want, not some over-inflated bureaucrats in Wellington."
