Surgeon Brings Minimally Invasive Techniques to Otago Region

Dr. Mark Smith has spent the better part of two decades bringing surgical techniques to the Otago and Southland regions that were once available only in major urban centers or overseas. His specialty is laparoscopic surgery—a method that replaces large, traumatic incisions with small openings through which a camera and specialized instruments can reach the problem. The difference in how patients recover is substantial: less pain, smaller scars, and a faster return to ordinary life.

The applications are broad. Gallbladder removal, once requiring a significant cut across the abdomen, now happens through ports barely larger than a pencil tip. Hernias in the groin and abdominal wall, which traditionally meant weeks of restricted activity, can be repaired with patients back to work in days. But perhaps the most transformative use of these techniques is in treating severe reflux disease. Patients who have taken daily medications for years—sometimes decades—can undergo a laparoscopic procedure that addresses the underlying mechanical problem, often eliminating the need for pills altogether and restoring a quality of life many had assumed was permanently compromised.

Weight-loss surgery, or bariatric surgery, represents another major focus of Smith's practice. For people whose weight has become a medical crisis, whose bodies carry conditions that feed on excess weight—diabetes, hypertension, joint damage—bariatric surgery offers a path to lasting change. Smith has been performing these operations in the region for more than fourteen years, building a practice around the understanding that obesity is not a failure of willpower but a medical condition requiring surgical intervention.

Smith's training prepared him for this work. He completed his medical degree and general surgical training in New Zealand, then pursued additional specialty training in laparoscopic and upper gastrointestinal surgery across three countries: Auckland, Edinburgh, and Portland. He earned a Master of Medical Science degree focused on evidence-based medicine, grounding his practice in research rather than habit. From 2009 to 2011, he worked as a specialist laparoscopic surgeon at Legacy Good Samaritan Hospital in Portland, Oregon, gaining experience in one of the world's leading medical centers. Then he made a deliberate choice to return to Southland, to work and raise his family in the region where he belonged.

Today his practice spans the geography of the lower South Island. His primary base is Mercy Hospital in Dunedin, but he maintains regular clinics in Invercargill and Queenstown. At Southern Cross Central Lakes Hospital in Queenstown, he performs selected procedures. He also offers gastroscopy and colonoscopy at MacMurray Queenstown, extending his diagnostic and therapeutic reach. He holds affiliated provider status with Southern Cross Health Society and NiB for hernia surgery, gallbladder surgery, and the diagnostic procedures, making his services accessible to patients with those insurance arrangements.

What Smith has brought to the region is not simply new equipment or techniques, though those matter. He has brought the possibility that surgery need not mean suffering, that recovery need not mean months of limitation, that conditions once managed only through lifelong medication might be resolved. For a region that has historically relied on traveling to larger centers for specialized care, his presence means that advanced surgical options are now available locally, with the continuity and familiarity that comes from seeing the same surgeon before and after the operation.
