Governor-General Dame Cindy Kiro has shared greetings from King Charles to Kiingitanga, on day three of the tangihanga for Kiingi Tuheitia.

Thousands of visitors from throughout the country have arrived arrived at Tuurangawaewae Marae on Sunday morning, to pay their respects to the head of the Kiingitanga movement, Kiingi Tuheitia Pootatau Te Wherowhero VII, who died early on Friday at the age of 69.

Kiro said she 'wore three hats' for her visit - as governor-general, on behalf of the people of Aotearoa, and to mourn as a sister with whakapapa to the Kiingi.

She gave paid tribute to the manaakitanga of the Kiingi and Kiingitanga, and their work in bringing people together, referencing the national hui held at Tuurangawaewae in January.

"I know that when Kiingi Tuheitia called the national hui a tau, only here could you have made that work with 10,000 people coming to that call.

"That is a testament, to you koro as you rest, but also to your people."

Over the past two days, the people of Tainui have had the chance to mourn their King, and now iwi from throughout the motu have arrived to pay tribute.

Guests included the Governor-General, members of the Rātana Church, and iwi including Te Arawa, Ngāti Tūwharetoa, Ngāti Kauwhata and Ngāti Hine.
