Critics say these vows are the most significant step backward for Maori rights in decades, and some have taken legal action.
The government of Prime Minister Christopher Luxon says its plans address voters' concerns, and are aimed at giving all New Zealanders equal rights.
Ngira Simmonds, the king's chief of staff, said in a statement that the gathering will discuss how the Maori translation of the Treaty of Waitangi can be upheld.
Former Prime Minister Jenny Shipley and former Governor General Sylvia Cartwright are both set to speak.
The prime minister met the Maori King earlier this week and said he was supportive of the meeting.
