The people of Waikato-Tainui gather at Turangawaewae marae at Ngaruawahia on Tuesdayfor a two day hui - which is designed to set the iwi on a new course for the future.
Guest speakers include former Fonterra chairman Sir Henry van der Heyden and a range of Maori business leaders.
Hui convenor Tukoroirangi Morgan says it will cover everything from how the tribe achieves social and economic prosperity for its members, to the support needed for King Tuhetia to strengthen the Kingitanga movement.
He says the manner in which the tribe set up structures in the 1990s is now the focus of honest and frank discussion.
Mr Morgan says the winds of change are blowing, and the iwi has to change and re-assess whether what it is doing now can remain the same for the next 20 or more years.
He says at times during the hui those present will have the chance to break into groups, and discuss how Waikato - Tainui can better position itself both structurally and strategically.
