Dame Whina Cooper, Eva Rickard and Titewhai Harawira led a hikoi at Waitangi in 1985. In 1990 she went to the Netherlands to ask the government there to take back the name "New Zealand" so that the original Māori name "Aotearoa" could be used instead. She is on the New Zealand Maori Council, and she is a talkback host at Radio Waatea. For many years Harawira has escorted New Zealand Prime Ministers at Te Tii marae, Waitangi, during Waitangi celebrations.

In 1989 she was jailed for nine months for assaulting a patient at a mental health unit she ran.
