The Ngāti Toa Rangatira iwi isn't impressed with David Seymour's contentious Treaty Principles Bill.

The three principles to be included in the bill have been released today - including 'Civil Government', the 'Rights of Hapū and Iwi Māori' and the 'Right to Equality'.

Te Rūnanga o Toa Rangatira chief executive Helmut Modlik says Seymour's proposition is lacking.

"Tino rangatiratanga speaks to the ability to continue to live your life according to your customs, to have responsibility for your people, your place to live according to your own tikanga. That's what was agreed - that's the only thing that makes sense."
