There are a number of components to that package. We've promulgated an updated national policy statement (NPS) on freshwater management. That had a number of new attributes in it that weren't previously regulated and has standards to achieve over a generation through plans that are promulgated by regional councils that have to achieve those outcomes, which are, essentially, based on aquatic health. The guiding principle that's being used here is te mana o te wai, which puts at the primary centre of water regulation the health of the waterway as the first priority; second, human needs—for example, drinking water—and, third, economic uses of the water.
