The tournament was named for Maori leader Henry Taiporutu Te Mapu-o-te-rangi Mitchell, who was born at Ohinemutu on May 5, 1877.
He was recognised as an authority on matters affecting Maori and organised countless committees, hui and public events in the Rotorua district.
He served as secretary of the Arawa Bowling Club, was honorary surveyor to the Rotorua Racing Club, secretary of the Bay of Plenty Rugby Football Union and the Rotorua sub-union, and a member of the Maori Advisory Board of the NZ Rugby Football Union.
In 1936 he was spokesman for Te Arawa in requesting the New Zealand Rugby Football Union not schedule a match with the touring Springboks because of the racial abuse evident on the 1921 tour.
The Tai Mitchell tournament began two years later when Mitchell presented the original Tai Mitchell Shield to be competed for by the then seven Bay of Plenty sub-unions of Apanui, Opotiki, Whakatane, Rangitaiki, Galatea, Rotorua and Tauranga.
