Tauranga Iwi Ngati Ranginui has launched a campaign to find more than 5,000 of its people spread around the country and overseas.
The campaign aims to get the majority of its estimated 10,000 strong population registered so they can have a say on the Crown's offer to settle the tribes long-standing Treaty claims.
Chairman for Te Roopu Whakamana o Ngati Ranginui Antoine Coffin says they want all of the Iwi, regardless of where they live, to have a say on the structure being proposed to manage what will be returned to the Iwi, if the majority of people support it.
He says all Iwi members need to register before 30 April 30 so they can vote.
Mr Coffin says the iwi is using high profile celebrities from Ngati Ranginui in an advertising campaign.
These include Betty-Anne Monga from Ardijah, artist Hone Ngata and former TV presenter Marama Gardiner.
