Direct Answer: Celebrity chef Simon Gault had to pay out of pocket for skin cancer surgery after Southern Cross Health Insurance declined coverage for his recommended Mohs procedure. The insurer stated the case did not meet its updated clinical eligibility criteria introduced in December 2025.
Southern Cross Declines Mohs Surgery Coverage for Celebrity Chef Simon Gault
Celebrity chef Simon Gault faced an unexpected medical bill after Southern Cross Health Insurance refused to fund a specialized surgery to remove skin cancer from his cheek.
According to Gault, his medical specialist recommended Mohs micrographic surgery, noting it offered a significantly higher chance of successfully removing all cancerous tissue. However, the insurer rejected the funding application because the case did not meet its specific clinical criteria.
Gault proposed paying the difference between the insurer’s standard excision rate and the cost of the specialized surgery, but the insurer rejected that compromise.
Insurers Tighten Criteria While Premium Costs Surge 75% in Five Years
The high-profile dispute unfolds as New Zealanders grapple with steep increases in private health insurance costs.
Stats NZ’s Consumers Price Index recorded an annual premium inflation rate of 19% in the year to the June quarter, as reported by the NZ Herald. Meanwhile, the Insurance and Financial Services Ombudsman handled 170 health insurance-related disputes in the year to June, marking a 91% increase compared to the previous year.
Southern Cross chief sales, marketing and customer experience officer Regan Savage defended the insurer’s approach, explaining that Mohs surgery is funded when it meets strict clinical eligibility requirements. Savage noted that standard surgical excision remains fully available when specialized criteria are not met.
Industry Experts Weigh the True Cost of Self-Insuring Versus Paying Premiums
The debate between paying ongoing premiums or saving money independently involves stark financial calculations. Russell Hutchinson, director of Chatswood Consulting, explained that insurance primarily protects against infrequent, catastrophic events rather than low-cost routine care.
However, Jon-Paul Hale, founder of Willowgrove Consulting, pointed out that self-insuring requires unmanageable amounts of savings. Hale calculated that an average person maintaining medical cover from age 20 to 70 would spend approximately $230,000 on premiums over their lifetime.
Hale cited a recent client claim totaling $265,000 over 12 months for early-stage breast cancer treatment. He noted that individuals would need decades of disciplined saving to cover such an expense independently, running the severe risk of a major health crisis occurring early in their savings timeline.
Policyholders Face Hard Choices Over Specialist Tests and Higher Excess Options
Financial advisers suggest policyholders examine their coverage closely rather than cancelling outright.
Fairbrother noted that health insurance functions primarily as a safeguard against major medical expenses running into tens or hundreds of thousands of dollars. “Self-funding can work if you’ve accumulated substantial savings, but many New Zealanders would absorb a major medical expense without insurance with great difficulty,” Fairbrother said.
For aging policyholders, adjusting coverage levels can provide relief. Hale suggested that policyholders around age 55 should evaluate whether specialist and test benefits—which cost couples about $250 a month—outweigh the potential claims, though dropping these benefits can revoke access to critical MRI and CT scans. Alternatively, Liz Koh of Enrich Retirement recommended opting for a higher excess to lower monthly premiums.
Common Questions Regarding Health Insurance Coverage and Policy Rules
Why was Simon Gault’s specific surgery declined by Southern Cross?
Southern Cross declined the Mohs surgery recommendation because the case did not meet the insurer’s updated clinical eligibility criteria, which were tightened in December 2025.
How much have health insurance premiums increased recently in New Zealand?
Health insurance premiums have risen by nearly 75% over the past five years, with Stats NZ recording an annual premium inflation rate of 19% in the year to the June quarter.
What alternatives do policyholders have if premiums become unaffordable?
Insurers and financial advisers recommend reviewing policies to adjust excess levels or modify specific benefits, such as specialist cover, rather than cancelling coverage completely and losing pre-existing condition protections.
