So it's a bill that's about efficiency; it's also one that enables us to move as the science moves. It enables the authority to take into account latest scientific data. So it's a good piece of legislation. It's a good way of getting the best out of taxpayer money, and it's also going to contribute to the wellbeing of New Zealanders, because obviously we don't want New Zealanders exposed unnecessarily to hazard from hazardous substances. So I commend it to the House.
