So where do we go with this bill going back to when it was originally introduced? What was being proposed was that Part 2A of the Health Act was being amended so that DHBs could be the decision makers and then they could direct local authorities in terms of fluoridating, or non-fluoridation, of their water supplies—because at the moment it is territorial authorities that have that decision making. But, back then, it was noted that the problem there was that you'd have inconsistent decision making around the country, so that only 54 percent of the population back then was receiving fluoridated water. And they were commenting back then that, basically, it hadn't changed in the past 15 years. So there was a real sense that we needed to do something. So what they argued was if you had DHBs that were the ones making the decisions, then you'd actually have a much more public health - focused approach in terms of that decision making; and that was the rationale for moving to DHB decision making.
