Professional Profile

Nigel Rajaretnam graduated with Honours from Trinity College Dublin, Ireland in 2008. He began his surgical training in Ireland, as part of the Basic Surgical Training (BST) and Basic Specialist Training (BSpT) programs. He became a member of the Royal College of Surgeons in Ireland in 2011. He then sought further training opportunities in New Zealand in 2012. He obtained his Fellowship of the Royal Australasian College of Surgeons in 2019. He undertook further post fellowship specialist training in Endocrine and Bariatric Surgery in Waikato Hospital in Hamilton in 2019. After completion of the Fellowship, he worked as a Consultant Surgeon at Waikato Hospital. Nigel then left New Zealand in 2021 with his young family to move back to Dublin for a year for a much coveted Fellowship position. He was the Fellow in Upper GI Surgery at the National Centre for Oesophageal and Gastric Cancer at St James's Hospital, Dublin. His fellowship was focused on Surgery for Upper Gastrointestinal cancers and Interventional Endoscopy. He was appointed as an Assistant Professor in Surgery at Trinity College, Dublin, during this Fellowship. To date - this is one of the proudest moments in Nigel’s academic career - to be back in Trinity College, contributing to the same medical school that trained him. Nigel is a Consultant Surgeon with specialty interest in Upper GI Surgery and Endocrine Surgery. He is excited to be able to offer clinical knowledge and skills to patients both at Intus Dunedin and at Te Whatu Ora (Southern), Dunedin Hospital.  He is also a Clinical Senior Lecturer in the School of Medicine with the University of Otago
