Mark Stewart

Mark Stewart, MB ChB (Otago), FRACS, completed medical school in 2008, and undertook general surgical training throughout New Zealand, being made a Fellow of the Royal Australasian College of Surgeons in 2016. During this training he gained a particular interest in treating obesity, as well as interests across general surgery more broadly, with the intention of serving provincial New Zealand. His skills in these areas were then consolidated with a year of extended scope general surgery at Royal Darwin Hospital, and a year of focused upper gastrointestinal and bariatric surgery training at Joondalup Health Campus, Perth. Mark has performed a high volume of bariatric surgery with an excellent safety record.

In 2019 he commenced as a General Surgeon in public and private practice in Nelson with responsibility for upper gastrointestinal surgery in the public sector.

Mark is a member of the Australia and New Zealand Metabolic and Obesity Surgery Society, of the New Zealand Association of General Surgeons, of General Surgeons Australia, and is a Clinical Lecturer with the Dunedin School of Medicine.
