Career
Sheriff Bain became a teacher in 1879 and was a strong campaigner for equality for women teachers, who were often paid half the salary of male teachers. In 1894 her father died and she moved to Christchurch, where she worked as a librarian and joined the Canterbury Women's Institute. She became the president, and in this role chaired the first meeting of the National Council of Women in 1896. Kate Sheppard was appointed the president of the council, Ada Wells secretary and Sheriff Bain treasurer. She was a passionate advocate for peace and arbitration, and presented a number of papers on these topics at conventions and meetings. She was particularly opposed to the Boer War and in 1900 delivered a strong anti-war speech at the conference of the NationalCouncil of Women. Newspaper editors disliked her opinions and the NCW distanced itself from her stance in order to avoid negative publicity. In 1899 Sheriff Bain moved to Auckland, where she taught at Queen Victoria School for Maori Girls, and then to Taranaki in 1902. In 1901 she was elected New Zealand's representative on the International Council of Women's standing committee on peace and arbitration, and in 1904 attended the ICW meeting in Berlin, followed by the Thirteenth Universal Peace and Arbitration Congress in Boston, U.S. From 1909 to 1913, Sheriff Bain lived in Riverton and worked as a journalist. She campaigned against compulsory military training, which New Zealand had introduced in 1909, and organised the Aparima Peace Union and, in Invercargill, the Women's Peace Society. She was also interested in issues of gender equality, equal pay, women jurors, prison reform and workers' rights. In her 70s, Sheriff Bain had two books published in England: an anthology of poems, From Zealandia, and a novel, Service: a New Zealand story. Sheriff Bain died in Auckland aged 95 on 26 January 1944.
