Gilmer was a member of the
Wellington Hospital Board from 1938 to 1953. As a result of her advocacy, the hospital developed the most up-to-date maternity service in New Zealand. Her perpetual interest in nurses' welfare led to vast improvements being made in the conditions under which they worked. She stood twice for Parliament unsuccessfully in both the and general elections in the electorate as an independent candidate, but declined to accept nomination for any political party, though in the latter she received tacit support from the National Party. Her campaign in 1935 was noted for large public audiences and large media attention, drawing a connection to the political career of her father Richard Seddon, the 15th Premier of New Zealand. ==Honours==
