Opposition MPs also don't seem to recognise that the Crown actually owns these lands: 1.2 million hectares of, largely, the eastern South Island, which is 5 percent of Aotearoa New Zealand. As landowner, the Crown wants to protect its interests in these lands, for all New Zealanders. As the late Dr John Hayward noted, they have many interests. It's not just their landscape values, their astonishing array of vegetation, the landscapes from the big river valleys of the Rangitata and the Rakaia, the matagouri shrublands—the much depleted habitat—but, as Dr Hayward noted, they've got huge economic value, particularly for water for downstream use, because it's tussock grasslands, which are really good at harvesting fog and water. That water goes downstream. It's used in horticulture and agriculture to provide drinking water. That and tourism are perhaps their greatest economic value. So the Government, in introducing this legislation, is modernising the regime to provide for better recognition and protection of the land's inherent values—its scientific, ecological, cultural values—while providing for sustainable farming on an ongoing basis.
