Ngai Tuhoe is due to initial a multimillion-dollar Deed of Settlement at Parliament on Friday.
Tuhoe and the Crown reached an agreement in September 2012 on a package, which includes a Crown apology and an acknowledgement of Treaty of Waitangi breaches.

The settlement will lead to the creation of legislation placing Te Urewera National Park under a new Governance Board, which will have an equal number of Tuhoe and Crown representatives.

Once the document is initialled, it will be taken back to the people for ratification.
