The Supplementary Order Paper also proposes some new powers and functions for Taumata Arowai, particularly in the area of waste water. These powers will provide much-needed national-level oversight and consistency around publicly owned waste-water networks. Amongst other things, Taumata Arowai will be able to set minimum environmental performance standards for waste-water networks, bringing Aotearoa in line with many other countries. The SOP also clarifies that Taumata Arowai's oversight powers extend to trade waste.
