The Kingitanga is calling on iwi to put representatives forward for a revamped advisory council, Te Kaumarua.
The original council was established in the 1860s, but faded out after its members died and weren't replaced.
The Kingitanga will re-establish Te Kaumarua and bring in 12 tribal representatives including those from outside Tainui.
Iwi with traditionally close links to the movement include wider Taranaki, Ngati Kahungunu, Te Arawa and Tuhoe.
Radio New Zealand's Te Manu Korihi understands the revamped council is seen by King Tuheitia as a way to give the motu a say over the direction of the kingitanga and a platform for Maori to discuss issues ahead of the elections.
