Reti ShaneDr SHANE RETI (Deputy Leader—National): Thank you Madam Speaker. It's a pleasure to speak to this bill which is a partnership bill—as the Minister described—to a previous piece of work we did Taumata Arowai—the Water Services Regulator Act 2020. That bill came to the Health Committee and this is an area that's much more complex than we otherwise might think. The very definition—as my colleague has alluded to—of domestic self-supply is quite complex and I don't imagine will be relitigated through this partnership bill. But certainly in the first bill that came to the House Taumata Arowai we grappled with questions around rainwater tanks—is Taumata Arowai applicable to a rainwater tank attached to a house or attached to a cafe? The answer was yes because a cafe is not for residential purposes; it has a different set of regulations. Is there a difference between rainwater and bore water? That was another complexity and we spent a lot of time in Health Committee trying to figure out the difference there and fundamentally settled on: no there's no difference for the purposes of this legislation. Mobile homes that fill up their water tanks from a domestic supply: does it matter where they fill up their water tank? If they fill it up from a domestic supply or if they fill it up from a commercial supply suddenly do the water regulations around that mobile home change? You can see some of the complexities we have to deal with in this whole discussion. I think we did a lot of the groundwork necessary for this bill to be able to move forward but we may find—even as we're progressing through this bill—that there are some definitions that might want to change. So a lot of complexities and please this is coming to the Health Committee. If we look at the fundamental actions of the bill the commitment to drinking-water supplies is to provide safe drinking water consistent with standards ensure there's an adequate quantity of supply to register their drinking-water supplies to have a drinking-water safety plan and to notify Taumata Arowai when there are risks to public health—it makes sense. The source water risk management is also described in this bill—drinking-water supplies must have a source water risk management plan. It's actually quite complex. We spent a lot of time on the risk management plans and local authorities must contribute their information to the risk management plan as well.I think the last thing I want to talk to on this bill is around some of the interesting points around the exemptions. I understand wanting to have that wriggle room particularly around the example used in the bill around chlorination. The Health Committee will want to explore this carefully because on one level fluoride can also be a disinfectant. We don't want to commit ourselves down a pathway here that might lock out future legislation that we were wanting to come to this House. So as we look at exemptions in the Health Committee we're just going to be guided by official advice so that we do what we want to do here which is effectively to give people exemptions if it's required give authorities exemptions if it's worthy and require—but not lock ourselves out of future legislation. I look forward to that coming to the Health Committee for further discussion. You can sense our support for this bill and its progress through the House and so we commend it to the House now.
