Hariata Ropata Tangahoe was born in 1952 and is of Ngati Toa, Ngati Raukawa, Te Atiawa and Welsh and Italian descent. She lives and works at Raumati Beach on the Kapiti Coast.

Hariata's work is in the Dowse collection, The BNZ collection and the collection of Te Papa Tongarewa, Museum of New Zealand. In 1987, Hariata's work was included in the exhibition Nga Taonga a o Tatou Kuia (The Treasures of Our Grandmothers) alongside artists including Kura Te Waru Rewiti and Robyn Kahukiwa.

Gregory O'Brien writing in Lands & Deeds (published 1996) says of Hariata's work

"Tangahoe's paintings can be the most innocent and, at the same time, the most knowing of things. They address, with equal amounts of urgency and lyricism, what literary critic David Sexton calls 'such shabbily unprofessional topics as life and death...' It is this proximity between art and the forces which govern life that gives the work its emotional directness and power. Tangahoe goes so far as to suggest painting itself can be prophetic, anticipating developments in her thought and life - saying "mystical, spiritual elements preoccupy me instead of the living problems here and now."
