She was born in Otaki, the grand-daughter of Wiremu Te Kākākura Parata and daughter of Nātanahira Te Umutapu W˚ Parata and ōriwa Tuni Horomona. She was raised at Whakarongotai, the family marae in Waikanae, and was educated at the Waikanae primary school and Hukarere College. She attended Wellington Teachers’ Training College and taught at the former Porirua School, Ngāti Toa School, Porirua East School and others, resigning from teaching in 1959. During the Second World War, she was part of a patriotic fundraising presentation called "Trooping of the Colours". She married Matuaiwi Solomon in 1947. She was a tutor in Māoritanga and a member of the Māori Writers and Artists’ Association. She was a J.P. and was awarded the QSO for services to the Māori Community in 1990. She was a trustee of the International Festival of the Arts in Wellington. She travelled overseas a number of times, attending the opening of the Polynesian Cultural Centre in Hawaii in the early 1960s. She stated: "I do a little painting and a bit of writing just for my own enjoyment. I’ve had some things published at our local polytech down here, also some journalism mainly in the local newspaper." She was recorded on the Radio New Zealand children’s holiday programme, ‘Hotchy Potchy’, which won an award the 1983 Ohio State Awards for radio and television programmes in the United States. This programme, produced by Piripi Walker and Lyn Chambers, involved Solomon and other Takapuahia Marae kaumatua talking with the children of the marae in a magazine-type programme.
