Ka āta wherawhera te Kāwanatanga i tētahi rīpoata kua puta i Te Kāhui Rangatira ā-Iwi mō ngā wai māori e kōrero mō ngā tika a te Māori ki ngā wai.
I whakatūria te Kāhui Māori nei i te tau rua mano mā whitu, ā, i te rangi nei i whakarauika atu ngā māngai o te Kāhui ki Rotorua.
Ko te kaupapa matua o tēnei rōpū, he kawe ā-kanohi atu i ngā whainga Māori mō te wai māori ki te Karauna.
