Andrew Day

Paediatric Gastroenterologist, Professor of Paediatrics

Andrew completed his medical training in Dunedin and then his early junior medical officer years in Christchurch. He started his paediatric training in Christchurch before moving to Sick Kids Hospital, Toronto, to undertake three years of specialist training (Paediatric Gastroenterology fellowship).

Andrew was then appointed to a clinical academic position as a paediatric gastroenterologist in Sydney, Australia (University of New South Wales and Sydney Children’s Hospital).

After nearly ten years in this position, he established his clinical, research and academic career. He then returned to Christchurch to take up a joint university (University of Otago Christchurch) and clinical role, where he remains to date.

Today, Andrew is a paediatric gastroenterologist based in Christchurch.

Andrew’s clinical role encompasses the care of children throughout the South Island with a range of gastroenterology, liver disease, pancreatic and nutritional conditions.

His academic role includes undergraduate and postgraduate student teaching, university administrative roles and ongoing research endeavours. Andrew’s research activities, supported by Cure Kids, focus predominantly on aspects of Inflammatory Bowel Disease (IBD) and coeliac disease in children and adolescents. He has supervised many research students over the years and presents his work nationally and internationally.

In addition, Andrew has been a trustee of Crohns and Colitis NZ for a number of years. He has chaired the Camp Committee for almost ten years, contributing to the success of NZ’s national annual camp for children with Crohns or ulcerative colitis.

He has contributed to the medical advisory panel for Coeliac Australia and chairs the medical advisory team for Coeliac NZ. For many years he has also been a trustee of the Gut Foundation, a Christchurch-based organisation focused on raising awareness, educating and providing advocacy about gut health and disease.

More recently, Andrew has been a member of the medical team for Nutritional Therapy for Inflammatory Bowel Disease (NTforIBD), a North American-based organisation that focuses on raising awareness about the impact of IBD upon nutrition and the roles that nutritional interventions play in the management of these conditions.
