Hon Dr AYESHA VERRALL (Associate Minister of Health): Thank you, Mr McKelvie, for that important question. Look, I'm an optimist about the issue of acceptance, and I think one of the things is that 50 percent of our population already live in places with a fluoridated water supply and, day to day, most people think nothing of it, to be honest, and people who visit, for example, Wellington from around the country where they don't have fluoridated water don't seem to raise it as a concern when they visit this great city.
