The tribe received a $31 million Treaty of Waitangi settlement in 2005, and has looked to build its asset. Pania Winterburn is its finance and investment kaiarahi, and is guided by a board.
Ms Broughton and her team of four work from upstairs offices in Wanganui's Victoria Ave. They're looking for new offices at ground level.
The tribe is working to a three-year plan, with multiple objectives for improving the lives of its members. The top three at present are education, economic development and care for the environment.
Above them all comes drawing the iwi (tribe) together. Only 13 per cent of its 4000 members now live within the tribal boundaries. Communication to draw in the others was vital, Ms Broughton said.
It's done through a website and Facebook, and there should also be a mobile phone app ready by the end of September.
On the education front Nga Rauru has a curriculum mapped out for its children from early childhood to Year 13. Resources for it will be developed next, and it should be "in full flight" next year.
"Within our rohe [tribal area] we want to be able to share our view of the world with our community," Ms Broughton said.
A "virtual learning kura [school]" is the eventual aim.
On the economic development front the iwi wants jobs and businesses. Ms Broughton helped set up its native plant nursery, Kii Tahi.
There are some ideas out there already but she was only willing to say that land figured strongly in them.
The tribe has given up its struggle to get ownership of the former Waverley High School property. Ms Broughton said the land and buildings had high holding costs and it was not clear how they could be an asset.
"There have been lots of ideas but nothing that gives us confidence that it's sustainable."
On the environment front, tribal members make an annual journey from the Waitotara Conservation Area down the Waitotara River to the sea. They are very interested in learning more about their seas and coastline. Trans-Tasman Resources' proposal to mine ironsand in the South Taranaki Bight was a challenge.
"It was very difficult for us to engage in that from a position of strength."
Members Turama Hawira and Raukura Waitai have been invited to the Te Poutama Maori Otago International Research Workshop in Dunedin this month. "Hopefully they will be bringing back some ideas and recommendations for how we as iwi can position ourselves and prepare for more development in this space."
