Celebrations started today to mark the seventh anniversary of the coronation of the Maori King - Tuheitia.
Tribes from throughout the country with ties to the King movement are making the journey to Ngaruawahia's Turangawaewae Marae.
The week-long event, known as the Koroneihana, includes a service for kawe mate - a memorial service for those who have recently died.
But high on the agenda for this year's hui is the issue of Maori rights to freshwater.
The Maori King's representative, Tukoroirangi Morgan, is inviting iwi to talk about the matter. Speakers will include Sir Eddie Durie and Toby Curtis.
