Mana-a-kiao, a direct descendant of Toi te Huatahi (Toi Kai – Rakau), married Tōrerenuiarua, the firstborn of Hoturoa, Upoko Ariki (Head Chief) of the Tainui waka, and his principal wife, Whakaotirangi, who also held Ariki status. Tōrerenuiarua was named after her father’s sister, HineTōrere, who passed away in Hawaiki before the Tainui migration. Her name also commemorates HineTōrere’s burial site on the island of Ni’ihau in Hawaiki.

Long before reaching Aotearoa, Tōrerenuiarua had foreseen the land she would one day settle. This prophetic insight guided her request to her father, Hoturoa, to land in the area now known as Tōrere. Her decision was deeply connected to her recognition of the ties between her people and the descendants of Te Tini o Toi, particularly Mana-a-kiao, who was mana whenua in the area. This meeting of genealogies and acknowledgment of local authority was crucial in establishing their presence in the region.

In recognition of Tōrerenuiarua vision and her significance, Hoturoa presented her with a sacred piece of the kei (stern of boat) of the Tainui waka. This taonga remains a powerful symbol of connection and heritage, depicted in the amo (carved posts) of the wharenui (meeting house) of her residing uri whakaheke (descendants).

The gift also carries the enduring whakatauāki (proverb) of Hoturoa…

This proverb encapsulates the enduring ties between the Tainui waka and the whenua (land), serving as a guiding principle for the people of Tōrere and their whakapapa. The story of Tōrerenuiarua is thus not only a tale of ancestral foresight but also a testament to the enduring connections between land, lineage, and identity.

A legacy of survival and sustenance was also embedded in the gift from Whakaotirangi to her daughter, Tōrerenuiarua. Whakaotirangi entrusted her with a kete (basket) rokiroki filled with purapura kumara (kumara seedlings) and taro, ensuring that her descendants, her uri whakaheke, would have the means to sustain themselves for generations.

This significant story weaves together lineage, foresight, and connection to the land. Her vision and foresight were instrumental in shaping the future of her people and underscores the deep connection between whakapapa, the land, and the resources it offers.

“Ka whangaia a Mana-a-kiao ia Tōrere, i te kai o te Rangatira, ka whāngai o runga, ka whāngai o raro ka puta ko Tainui, nā Tainui ko Tairoa, nā Tairoa ko Tai-manawapohatu, nā Tai-Manawapohatu ko Tai! Ko Ngāi Tai e tau nei!”

Mana-a-kiao fed Tōrerenuiarua according to her chiefly status, and together they became the progenators of the Ngāi Tai people beginning with their son Tainui; Tainui beget Tairoa; Tairoa beget Tai Manawapohatu; Tai-Manawapohatu beget Tai. From Tai descends the people of Ngāi Tai.

The Ngaitai Iwi Authority was originally established under a Trust Deed on the 3rd of October 1988 ("the original Trust Deed").

As a result of a hui at Torere Marae on the 26th of November 1987, the iwi of Ngāi Tai agreed to establish a body to operate under the mana of the iwi to advance the wellbeing of the iwi, socially, economically and culturally, which includes the scope for historical Treaty settlement negotiations with the Crown.

Registered as a Charitable Trust in October 1988 and then registered with the Charities Commission in 2008 and re-registered again in 2023, Ngaitai Iwi Authority is administered by the Board of Trustees who are accountable to Ngai Tai Iwi. There are seven Trustees on the Board. The Board exercises strategic Governance over the Ngaitai lwi Authority and its asset holding companies and subsidiaries.
