Mtintso was the daughter of Hanna Mtintso, a domestic worker, and Gana Makabeni, a labour leader and ANC activist. She left secondary school to help support her family, completing her education by correspondence courses while working in factories.

She was also a reporter for the Daily Dispatch, a liberal newspaper edited by the white antiapartheid campaigner Donald Woods. During the 1970s she was subjected to banning, detentions, solitary confinement, and severe torture by the South African police. After Biko was murdered while in police custody, she went into exile in 1978.
