Hon Dr AYESHA VERRALL: This Government takes the importance of safe drinking water extremely seriously, and that is the basis of our three waters reforms, which include alterations to the regulations of drinking water in response to the events of drinking-water contamination at Havelock North. With respect to the question about the precautionary principle, we will act on evidence, and, as I have mentioned, the evidence in this issue is unclear. I've had the experience in this role of having to stop a town from drinking its drinking-water supply, and it is incredibly disruptive. So I am happy with an approach where we act on conclusive evidence.
