"The progression of Treaty of Waitangi claims against the Crown has a long and important history in Wairoa, stretching back to the early 1980s," he said.
"Our goal has always been to achieve the best result for our iwi and hapū, and we believe this settlement will allow us to move towards a better future - economically, socially and culturally."
Whakaemi is made up of seven clusters representing iwi and hapū across the Wairoa district, including Rongomaiwahine (Ngāi Te Rākatō), Ngāti Rākaipaaka, Whakakī Nui a Rua (Ngāti Hine, Ngāti Hinepua, Ngāi Te Ipu and Ngāi Tahumatawhāiti), Ngāti Kahungunu ki Te Wairoa (including both Te Wairoa Tāpokorau 1 and 2) and Ngā Tokorima a Hinemanuhiri.
The Wairoa-Waikaremoana Māori Trust Board are also part of Te Tira in representing the interests of Ngāti Hinemihi, Ngāti Hinehika and Ngāti Hingānga.
Te Tira will stage hui throughout New Zealand from July 22 to August 7 for the people to get more information, register as members of the iwi, and to vote on the settlement.
"For our settlement to go ahead, we need our people to vote in support," Mr Olsen said. "We want everyone to be a part of this. It's our chance to build a better future for our whānau, our tamariki, and all the generations after them."
