She is best known for her co-authorship (with Phillida Bunkle) of a Metro magazine article that alleged that women had been experimented on, without their consent, at National Women's Hospital in Auckland. The article, titled 'The Unfortunate Experiment', led to the controversial Cartwright Inquiry, which confirmed the article's allegations. The article and the subsequent inquiry are seen as a turning point in healthcare ethics in New Zealand.
Coney has been involved in other women's health causes, and in 1984 co-founded with Bunkle Women's Health Action to co-ordinate claims by women who had been injured by the Dalkon Shield IUD. Coney was the co-founder of the feminist magazine Broadsheet, which she co-edited for 16 years. She is the author or editor of 14 books, including the major Suffrage Centennial publication Standing in the Sunshine (1993), which was also a television series. She wrote a regular column of political and social comment for the Sunday-Times for 16 years from 1986.
She is also involved in the local politics of the Piha area such as the unsuccessful campaign against the Piha cafe. She has also written an history of Piha and is currently researching Anzac soldiers from the Piha area.
Her father was Tom Pearce, who was ARC chair from 1965 to 1976 and a New Zealand Rugby Football Union administrator.

In October 2010, she was elected as a representative of the Waitakere Ward on the Auckland Council on the Best for the West ticket. She was also elected as an independent representative on the Waitemata District Health Board.
In the 2013 Auckland local elections Coney stood down as a councillor, endorsing fellow Future West candidate Christine Rose for the position. She was re-elected to the Waitemata District Health Board, and was elected to a new role as chair of the Waitākere Ranges Local Board, having received the most votes of any of the board's members.
