Every cancelled health insurance policy in New Zealand is a client a broker did not hold onto, and there are more of them than at any point in recent years.
Research commissioned by the Financial Services Council shows 9% of health insurance holders cancelled their cover last year, up from 7% in 2022, while premiums have climbed almost 75% over five years. That combination lands directly in the renewal conversation brokers are having with clients right now.
The average health insurance claim paid per member rose from $1,097 in 2021 to $1,921 in 2025, nearly doubling in four years. FSC chief executive Kirk Hope put it plainly: "Just as New Zealand needs every part of the health system working better together, people are cutting back the very cover that helps them access care sooner."
Southern Cross, New Zealand's largest health insurer, shows what that pressure looks like on a balance sheet. It posted a net deficit of $51.8 million for the year to June 2025, with its health insurance arm alone $56.9 million in deficit, while membership fell by 3,493 to 951,808. It paid out $1.706 billion in claims against $1.811 billion in premium income - 94 cents returned for every dollar collected.
AIA NZ tells a different story with its own numbers. It paid $790.3 million in claims for the year to December 2025, down 4.7% from $829.6 million in 2024, and its claims acceptance rate slipped one point to 91%.
That divergence is directly relevant to a broker weighing up carrier recommendations: one insurer is absorbing rising claims and losing members, the other is paying out less while tightening acceptance. Neither trend is inherently a red flag, but both are worth factoring into a placement decision rather than defaulting to whichever carrier a client already holds.
That divergence sits alongside a broader question about who stays insured, not just how many people do.
New Zealand remains one of the most underinsured countries in the OECD, according to the FSC's own State of the Sector report, and at least one major insurer has been explicit that its recent product moves are about retention economics.
AIA NZ's July 2026 tie-up offering supermarket discounts to Vitality members was described in trade coverage as being about the risk pool, not the rewards, built on the logic that engaged members are cheaper to insure over time.
Comparable-market analysis by RGA, of Discovery's Vitality programme, found engagement of that kind cut lapse rates by 15% among enrolled members. That is a concrete data point brokers can use in a renewal conversation with a client considering walking away: staying engaged with a policy's benefits, not just paying the premium, measurably reduces the odds of lapsing.
Aon's Global Medical Trend Rates Report forecasts New Zealand employee healthcare costs to rise 18% in 2026, against a 9.8% global average. UniMed, a group-cover insurer, paid out more than 180,000 claims in the year to June 2025, up 53% on the year before, with average daily claims paid climbing from $394,000 to $612,000. None of that makes next year's renewal conversations any easier.
A client who cancels cover entirely typically has to go through underwriting again to take out a new policy, meaning any condition that developed in the gap can end up excluded. That is a duty-of-care point worth raising proactively, since a client focused on the premium saving may not weigh the reunderwriting risk on their own.
Around 35% of New Zealand adults hold private health insurance, and 43% of that group get it through an employer or workplace scheme, which is community-rated and avoids the lapse-and-reunderwrite problem entirely.
Hope wants fringe benefit tax removed from employer-funded schemes: "It's a very effective way, it's community-rated and it's not underwritten so it's a very effective way for people to get access if the employer is providing low-cost or no-cost health insurance for them, but it's very expensive for employers because they have to incur a 50 percent to 70 percent tax on premiums."
Coverage of the proposal has framed it as an election issue that could change how group schemes get pitched to business clients: removing FBT would lower the effective cost of employer-funded cover without any change to premium pricing itself, which gives a more straightforward commercial case to put in front of an employer weighing up whether to offer group cover at all.
An internal government aide-mémoire pushes back, arguing that subsidising private health insurance through the tax system is generally poor value: people who would buy cover anyway would get a discount they did not need, while those with the greatest health needs would likely still find premiums out of reach even with an exemption.
If the exemption does not pass, the retention argument built on engagement products and reunderwriting risk carries more of the weight. Lapse rates rising, two major carriers moving in
different directions, and a tax proposal still stuck in political limbo all point to the same practical question at renewal: whether a client stays insured or walks. The data here does not just describe a market trend - it provides retention economics, reunderwriting risk, and a stalled tax pitch that a broker can use directly in the next conversation with a client thinking about dropping cover.
