Surgical options for long-term weight loss
At WLS, we offer a full suite of evidence-based bariatric procedures – each designed to support lasting weight loss, improved health, and a better quality of life. Every patient is different, which is why we take the time to guide you through the benefits, risks, and suitability of each option. Surgery can be life-changing – but it must be the right fit for you.
Our primary procedures
Each of the surgeries below has unique characteristics, and your individual health history, goals, and preferences will determine which is most appropriate.
Sleeve Gastrectomy
Currently the most common weight loss procedure in New Zealand. Removes part of the stomach to reduce volume and hunger cues.
One Anastomosis Gastric Bypass
Sometimes referred to as a “mini” gastric bypass, this option is highly effective and increasingly popular for patients with a higher BMI.
Roux-en-Y Gastric Bypass
A well-established surgical method with over 50 years of international data. Suitable for both weight loss and reflux resolution.
Conversion/revision Bariatric Surgery
For patients who have had previous weight loss surgery and are now seeking further support due to complications or weight regain.

Your Body Mass Index (BMI) helps assess whether you might benefit from surgery.
We’ll send you an easy-to-read guide that outlines options, eligibility, and what to expect.
