As I mentioned, this bill will set up a nationally consistent decision-making process. Local factors will be taken into account, including the oral health of the population and the feasibility of fluoridation, the implementation readiness at each locality. But we will not be relitigating the science of fluoridation in every district in the country. The science of fluoridation is settled, just like the science of seatbelts and the science of vaccination. That isn't to say locally-led action doesn't have an important role in public health. It absolutely does, as we have seen through the Vaxathon, and it's important in building healthy environments, for example as we could to promote smoking cessation. But, too often, devolution of public health functions has led to an abdication of Government responsibility for public health. Devolved fluoridation asks councils to evaluate technical health information and sometimes disinformation without the resources to do so. Many local authorities submitted in favour of this bill because they felt they were being asked to make a technical decision they were poorly equipped to take. This bill reflects the Government's commitment to protecting the health of New Zealanders. This is about taking responsibility.
