Cruickshank attended the
University of Otago Dunedin School of Medicine and was the second woman, following
Emily Siedeberg, in New Zealand to complete medical school, graduating in 1897. She went into general practice (the first woman in New Zealand to do so) in
Waimate initially through an assistantship with established doctor HC Barclay. She continued her studies and was awarded an MD in 1903. The next women in New Zealand to graduate in medicine were in 1900:
Alice Woodward,
Daisy Platts and Jane Kinder. In 1913 Cruickshank completed postgraduate studies in Edinburgh and Dublin, travelling also to Europe and America. To show their esteem, the people of Waimate presented her with a gold watch, chain and a purse of 100 gold sovereigns, at a public function before she left. The Waimate Museum displays this gold pocket watch. The inscription inside the watch case reads: "Presented to Margaret B Cruickshank, from her many Waimate Friends Feby. 13th 1913." During World War I she organised the work of the Waimate Red Cross Fund, and took over the case load of her partner, Dr Barclay, who had enlisted and gone overseas. She was also one of three doctors who shared his role of hospital superintendent in his absence. When the
1918 flu pandemic broke out, Cruickshank worked night and day, caring for the children of ill parents, cooking meals for them and even milking the cow of a family whose adults were too ill to do so themselves. Eventually she fell ill herself and died on 28 November 1918. ==Legacy==
