During his 10-year reign King Tuheitia has made a "significant and sustained" contribution to Hamilton, said deputy mayor Gordon Chesterman, extending from development projects to setting up tertiary scholarships and colleges.
In the lead up to the week the King's wife Atawhai, daughter Ngawai Hono i Te Po Paki and cousin, Labour MP Nanaia Mahuta, all received moko kauae - chin tattoos for women.
Other events include a presentation of the title and gazette vesting order of Rangiriri Pa by Minister of Arts, Culture and Heritage Maggie Barry to the King, a memorial for deceased iwi members, a cabaret dinner featuring singer John Rowles, a sports competition, disco evening, kapa haka performances and a royal extravaganza performance.
Turangawaewae spokeswoman Moko Templeton said the celebrations had been a year in the planning and several thousand guests were expected across the week.
Despite ill health from diabetes including hospitalisation in recent years, King Tuheitia only 12 months ago launched a claim for Auckland extending north to Mahurangi, down the Firth of Thames and across to the Manukau Harbour and Piha, telling followers he was determined to see it through.
Templeton said the King was in good health at the moment and was being kept busy with the preparations.
The seventh monarch in the Kingitanga movement serves as a patron, chair or appoints individuals to key leadership roles in 56 organisations.
His contribution to education includes the development of five-yearly nursing scholarships in memory of his mother at Wintec worth $25,000.
At a national level King Tuheitia has contributed significantly to cultural and religious unification.
The reformation of a national tribal council, Tekaumarua, is attributed to the King and he convenes Kahui Wairua, a hui of Maori and Pakeha religious leaders.
