Sansom became an honorary curator at the
Southland Museum in June of 1948, having previously volunteered there. From March 1953 until 1959 she was director of the museum, making her New Zealand's first female museum director. As director, she was assisted by volunteers to develop displays on natural history, teach visiting school children, and identify biological specimens brought in by the public. Sansom collected botanical specimens that included seaweeds, alpine and bog plants, lichens and ferns over the course of more than 50 years. In 1956 she was invited to give the Banks Lecture on botany at the annual conference of the
Royal New Zealand Institute of Horticulture. She was also a keen birdwatcher, and a founder member of the
Ornithological Society of New Zealand. == Family ==
