I would also note that the Attorney-General's opinion on this, in my view, has unfortunately not delved into this in any great detail. It's just said that "The Treaty of Waitangi settlement agreed between Ngāi Tahu and the Crown in November 1997 acknowledged the rangatiratanga and mana of Ngāi Tahu over their lands … and affirmed their 'special association' with the natural environment in a number of areas." It said, "On the basis of this, the Settlement awarded Ngāi Tahu positions of input into environmental management bodies throughout the South Island/Te Wai Pounamu. This included establishing a Ngāi Tahu statutory adviser position to the Department of Conservation and awarding dedicated seats to appointees of Te Rūnanga o Ngāi Tahu on the New Zealand Conservation Authority and on Conservation Boards within the Ngāi Tahu Claim Area." It goes on to say that it thinks that although this could ostensibly be seen as discriminating against others because they can't be appointed unless they're Ngāi Tahu, they think because of the special relationship, this bill is justified.
