The arrival of the noble Ariki for the second koroneihana (coronation) of Māori Queen Nga wai hono i te po, titled Te Arikinui Kuini, demonstrated the bond the traditional chiefs of the Pacific hold with the eighth-ever Indigenous monarch of Aotearoa.

The commemoration is said to embody age-old connections through whakapapa (genealogy), reo (language) and culture the Māori lineage shares with the great Polynesian houses that have solidified in the Kiingitanga movement into 21st-century Aotearoa / New Zealand.

The koroneihana, an anniversary of the Queen's accession and reign, is a multi-day celebration. The Kiingitanga - the Māori monarchy established in 1858 - confirmed that representatives of the Cook Islands/Kūki 'Airani, Fiji, Hawaiʻi, Tahiti and Tonga Ariki will all congregate together.

Samoan Prime Minister La'aulialemalietoa Leuatea Schmidt, who is the highest Samoan matai (Ariki chief) in the land, will not be in attendance as he will be engaged with the Pacific Islands Forum Leaders' Meeting in Palau.

Kaumaiti Nui Travel Tou Ariki, the House President of Ariki, Ratu Tevita Uluilakeba, a Tui Lau and paramount chief of Fiji's Lau province, the Kawānanakoa royal family, the Pomare royal family and the Crown Prince Tupoutoʻa ʻUlukalala will reinforce their cultural royal ties at the Tūrangawaewae Marae, the official headquarters of the Kiingitanga, in the Waikato township of Ngāruawāhia.

Kiingitanga spokesperson, Rahui Papa, a Māori academic, said the importance from the lineage of the Māori King movement to the "great houses" of the Pacific were solidified during a 1940s tour.

Princess Te Puea, born in 1883, and Princess Piki, who later became Te Arikinui Dame Te Atairangikaahu, born in 1931, both met with Queen Sālote Tupou III of Tonga while attending the double weddings of the Queen's sons.

The two Māori royal members went on to meet with the Pa Ariki of the Cook Islands, the Māori hereditary descendants of that title, and onto meet other Polynesian chiefs, including from Samoa and Tonga, across the Pacific.

Mr Papa also told the story of Te Arikinui Dame Te Atairangikaahu, the paternal grandmother of the reigning Māori Queen, playing a key role in establishing the Pacific Islands Forum, as its first Queen and the longest serving Te Arikinui monarch from 1966 until 2006.

"In the times of Te Arikinui Te Atairangikaahu, they set up the South Pacific Forum with big names, like Malietoa (Tanumafili II) of Samoa, Ratu (Sir Kamisese) Mara of Fiji, the King of Tonga Tāufaʻāhau Tupou IV," he said.

"A whole lot of those connections are still happening today."

The Ariki lines will first connect on Friday morning with New Zealand Governor-General Dame Cindy Kiro, the first Māori woman in the role, who is of Ngāpuhi, Ngāti Hine and Ngāti Kahu descent.
