CHRIS BISHOP (National): Speaking to the point of order, I want to echo exactly what Mr Hipkins just said then, and also what David Seymour said in his contribution. The simple reality is that we have a political constitution in this country, in the sense that it's for the Parliament to decide our constitutional arrangements, and the reality is that the Treaty of Waitangi, signed between Māori and Pākehā settlers into New Zealand, is something that will always be, and has always been in the time we've had parliamentary democracy, the subject of intense debate in the Parliament. That's the reality, and we should not inhibit debate around that in this House.
