"You can rest assured that we have turned over every stone in the awa to push this process right to the end."
Getting to this stage felt like a dream to him.
"We are now making this dream a reality," he said.
The tribe is asking for partnership, reconciliation and recognition from the Crown, and its "attempts to make Ngati Rangi invisible" are to stop.
Ngati Rangi wants help for the environment, and prosperity and well-being for its people.
The proposed settlement package will include an agreed account of Treaty of Waitangi breaches up until 1992, and an apology.
It also wants cultural redress, including a recognition of the Whangaehu River that will be similar to that accorded the Whanganui. The Whangaehu is unique in New Zealand, Mr Wilson said, being naturally mineralised from its source at Mt Ruapehu's Crater Lake.
Ngati Rangi wants the Whangaehu catchment's health and well-being protected, and a say in decisions about it. The iwi has already embarked on fencing and planting 60km of waterway, with the help of Government's Freshwater Improvement Fund and a tribal contribution of $450,000.
It also wants to work with the Conservation Department on decisions about land in its area, and it wants provision for members to take important stone resources from Mt Ruapehu and its rivers.
It's asking for a cultural fund of $167,000, and ownership of the bed of Lake Rotokura. Under the settlement it would receive and symbolically gift back Defence Force land near Waiouru.
Its financial redress of $17 million could be used to buy back land in the Karioi Forest, and other Crown property it will have first right of refusal on.
The tribe's claims within Tongariro National Park are another matter. Addressing them, along with those of other iwi, will begin in 2018.
