"It's an exciting stage."
While it is possible that the change in government may slow the process slightly as new ministers get up to speed, Mr Hirini said the timeline had not been officially revised and settlement was hoped for February 2018.
"The timing is good now to try a collaborative approach involving the wider community, instead of individual groups all acting alone," he said, adding that there was a need to attract people with the right skillsets to develop projects for the post-settlement era.
UCT chairman Aiden Gilbert said they didn't have to wait for the Treaty settlement to start "chipping away at all there is to be done".
He said the new Social and Cultural Trust would "allow our people to build a solid foundation for the work that lies ahead".
Acknowledging the partnership between Maori and the Crown "coming together for the common good of the whānau, hapū and iwi of the district", Mr Gilbert said the trust would be "a critical platform or incubator for growing alliances and partnerships, and generating strategies that will help drive the social and cultural aspirations of Uenuku, Tamakana and Tamahaki".
"At the centre of this launch is a value that strikes to the heart of Uenuku, Tamakana and Tamahaki - that is the care and respect of our cultural repositories, the caretakers of our marae, the leaders of our whānau and the teachers of our mokopuna."
"This is a milestone initiative that all of us can be proud of and, as a tribal authority, we are excited about the changes this new entity has the potential to make for our people."
The launch of the new trust will be followed by a public screening of an historic film from the archives of Ngā Taonga Sound and Vision, featuring many whānau of the Whanganui River and the Waimarino. The public screening will take place at the Theatre Royal, Seddon Street, Raetihi at 6.30pm Wednesday evening.
