Our surgeons

Jason Robertson is a New Zealand–trained general surgeon specialising in upper gastrointestinal, bariatric, and advanced laparoscopic surgery. He works as a consultant surgeon at North Shore Hospital and in private practice.

Following advanced training in general surgery, Jason completed subspecialist fellowship training through the Australia and Aotearoa New Zealand Gastric and Oesophageal Surgery Association (AANZGOSA), undertaking three years of high-volume upper gastrointestinal and bariatric surgery across Australia and New Zealand.

He has a strong clinical focus on complex upper gastrointestinal conditions, including reflux disease, hiatus hernia, obesity, and gastro-oesophageal cancer. Jason is particularly experienced in revisional surgery and caring for patients with ongoing symptoms or complications following previous procedures, with an emphasis on achieving durable long-term outcomes and improving quality of life.

Jason is currently the only surgeon in New Zealand offering the full range of internationally recognised bariatric procedures, allowing treatment to be carefully tailored to each patient’s individual needs and goals.

Alongside his clinical work, Jason is actively involved in research and in the training of surgical registrars and fellows in advanced upper gastrointestinal, bariatric, and anti-reflux surgery.
