Cheap “fly-in, fly-out” offers for weight loss surgery are flooding social media feeds across Aotearoa. The pitches are slick, the prices look irresistible, and the promises are grand. But behind the glossy marketing, too many Kiwis are returning home with serious complications, unexpected costs, and no clear plan for follow-up care. As specialists in the surgical management of obesity, Bay Surgery believes you deserve the full picture before making a life-changing decision.

Why overseas weight loss surgery offers can be risky

Aggressive targeting. Paid ads often focus on communities already carrying the greatest health burden, presenting surgery as a quick fix rather than a clinical pathway.

Unknown outcomes. In New Zealand, bariatric outcomes are recorded and audited, giving patients and clinicians visibility of complication rates and long-term results. With many offshore providers, there’s no transparent denominator—so the true risk is unclear.

Long-haul travel and surgery don’t mix. Flying shortly before or after an operation raises the risk of blood clots and other complications. Add language barriers, differing standards, and limited recourse if something goes wrong, and the risk profile grows.

Continuity of care. Safe bariatric surgery is a programme, not a one-off procedure. Pre-operative assessment, medication review, nutrition planning, and psychological support all matter—as does structured aftercare for vitamins, reflux, bloods, and weight maintenance. That continuity is hard to deliver from thousands of kilometres away.

Hidden costs. A “low” quoted price may not include revisions, treatment of leaks or bleeding, management of reflux, or any follow-up at home. When complications arise, patients can face multiple re-operations and prolonged hospital stays.

Sleeve vs bypass: the right operation for the right patient

Gastric sleeve surgery removes a large portion of the stomach and can be effective—but it isn’t right for everyone. People prone to reflux, or with certain metabolic needs, may be better served by gastric bypass, which alters the route of food and has powerful effects on type 2 diabetes and weight regulation. Choosing the wrong operation increases the risk of chronic heartburn, suboptimal weight loss, or weight regain. A careful, individual assessment is essential.

How Bay Surgery keeps you safe

Comprehensive assessment. We evaluate medical history, medications, sleep apnoea, reflux, nutritional status, and lifestyle. You’ll receive clear counselling on risks, benefits, and alternatives—including non-surgical options.

Evidence-based procedure selection. Weight loss surgeon Dr Daniel Mafi performs both Gastric Sleeve and Gastric Bypass, recommending the operation that best aligns with your health profile and goals.

Structured aftercare. Surgery is the start, not the finish. We provide a supported pathway that typically includes:

• Dietitian-led nutrition and supplementation plan

• Monitoring for reflux, micronutrient levels and weight trajectory

• Guidance on physical activity and behaviour change

• Ongoing access for questions and early review if issues arise

Transparent standards. We work within New Zealand’s regulated framework and shared reporting culture, so outcomes and complications are tracked and learnings are continuous.

Red flags in online offers

• One-size-fits-all recommendations (“sleeve suits everyone”)

• No named surgeon or no opportunity for a pre-op consultation

• Minimal aftercare (“two weeks of WhatsApp check-ins”)

• No plan for complications or for coordination with NZ clinicians

• Pressure tactics (“limited spots”, “book this week for discount”)

Considering surgery? Do this first

1. Speak with your GP. Ask about public pathways and whether you meet criteria for referral.

2. Get an in-person specialist opinion. Understand sleeve vs bypass, expected results, risks, and aftercare.

3. Ask about the whole programme. Nutrition, psychology, blood tests, vitamins, and follow-up frequency matter as much as the operation.

4. Plan long-term. Bariatric success is built on support, monitoring, and habits—not marketing promises.
