Ensuring that we are connected on key kaupapa will be important as we start to consider the wider issue of the outstanding maunga settlement and his enduring care.”
The whanaunga iwi include Ngāti Rangi, which shares affiliations with Ngāti Tūwharetoa to the mountains within Tongariro National Park - Ruapehu, Tongariro and Ngauruhoe.
The book value of Ruapehu Alpine Lifts is estimated to be more than $50 million.
