The issue of Ngapuhi sovereignty, after a landmark Waitangi Tribunal decision, will be under the spotlight at the marae near Moerewa with some high-profile New Zealanders leading the debate.
In November the Waitangi Tribunal ruled that Ngapuhi did not cede sovereignty to the Crown when its rangatira signed the Treaty of Waitangi.
Te Kotahitanga o nga Hapu Ngapuhi instigated the inquiry and co-chairman Pita Tipene said the hapu and whanau of Tai Tokerau were elated because their case that sovereignty had never been ceded to the settler government had been vindicated.
Mr Tipene said the ruling meant that the way the country had been governed might need to be looked at and changed to give more autonomy to hapu. However, the Government has said nothing will change.
A large gathering is expected at Otiria on Friday and Saturday when a strong line-up of keynote speakers will start a robust discussion and debate around He Whakaputanga (Declaration of Independence 1835) and the Treaty of Waitangi.
