What Treaty Principles? There are none.
The Attorney General responded to my request for a copy of the Principles of the Treaty of Waitangi by saying that there is no ‘authoritative copy’ of the Treaty Principles, but he said they have been ‘explored and discussed’ by the courts and the Waitangi Tribunal. (Letter available from the Attorney General’s office – just write and ask him for it.)
Exploration and discussion does not a principle make.
