Leading New Zealand Bariatric Surgeons

For over 15 years, our team of Surgeons, Dietitians, Clinical Psychologist and now an Obesity Medicine Specialist are helping thousands of people significantly improve their health and transform their lives. We specialise in modern, comprehensive obesity treatment. This includes evidence-based treatment with lifestyle modification, GLP1 medications and surgery. We specialise in gastric bypass, sleeve gastrectomy and revision bariatric surgery.

Our team has trained and worked in some of the world’s most renowned hospitals and medical facilities. The techniques we use are the latest in keyhole and laparoscopic options.

Working together, we assess, diagnose, advise, treat and manage your health and wellbeing from day one. We provide comprehensive follow-up to make sure you achieve the best possible outcome.

We regularly have patients travel to Christchurch for surgery from all over New Zealand, and we are very happy to work with you to arrange your appointments to maximise your time here. We are also able to offer your follow-up appointments by phone or video link to reduce your travel.
