Dr Mark 'Mark Omundsen' Omundsen


I am a Colorectal, Laparoscopic and General Surgeon.  I attained my Royal Australasian College of Surgeons (RACS) Fellowship in 2009 and successfully applied to the Colorectal Society of Australia and New Zealand (CSSANZ) subspecialty Colorectal Fellowship program the same year.  I spent the next 2 years gaining subspecialist expertise in the field of colorectal surgery and successfully completed the fellowship program in 2011. 

I am especially interested in minimally invasive approaches such as laparoscopic and single incision laparoscopic surgical (SILS) techniques in the management of colorectal diseases, abdominal wall herniae and gallbladder pathology.

My subspecialty interests include surgical management of colon and rectal cancer, inflammatory bowel disease, rectal prolapse and defaecatory disorders such as incontinence and obstructive defaecation. 

I am accredited with the New Zealand Conjoint Committee for the performance of both upper (gastroscopy) and lower (colonoscopy) gastrointestinal endoscopy.

I have been working in Tauranga Hospital as a consultant Colorectal Surgeon since 2012 managing a wide range of general and colorectal pathologies. I am actively involved in training junior surgeons and clinical research at the public hospital.
