New Zealand’s insurers are being asked to absorb a new annual regulatory cost at a moment when each major segment of the sector – general, health, and life – is navigating its own distinct pressure, and when the proportion of uninsured households is already rising. The Reserve Bank of New Zealand – Te Pūtea Matua (RBNZ) opened consultation on August 11 on a proposed prudential levy, on behalf of Finance Minister Nicola Willis. Announced as part of Budget 2026, the levy would take effect in August 2027. Submissions close at 5pm on October 16, 2026.
The insurance sector’s proposed share of the total levy is 39%, translating to approximately $27.3 million annually across an estimated 66 licensed insurers. Insurance Council of New Zealand (ICNZ) market data shows the general insurance sector recorded gross written premium of approximately $10.5 billion in the year to December 2025, meaning the sector levy represents roughly 0.26% of that figure in aggregate. The Financial Services Council of New Zealand (FSC) reports life insurance annual premiums reached $3.31 billion as at March 2026. Across both segments, the cost is manageable at industry level – but the distribution across individual insurers is far from even.
The RBNZ’s preferred model combines a $30,000 fixed floor per insurer with a variable rate of 0.13749% applied to gross New Zealand revenue. An insurer with $4 billion in revenue would pay approximately $5.53 million annually. One with $10 million in revenue faces roughly $43,749 – of which the fixed component is the dominant charge, functioning as an effective 3% levy on revenue before the variable rate applies at all. That asymmetry is the design detail brokers should track most closely. Smaller and specialist insurers – the carriers brokers rely on for niche or hard-to-place risks – carry the highest proportional burden. The Reserve Bank’s own consultation paper acknowledges that regulated entities “may then decide to pass on some or all of these costs to their customers.”
The levy lands differently across the three segments, but none is entering 2027 from a position of ease. In general insurance, ICNZ data shows gross written premium fell from $10.79 billion in 2024 to $10.55 billion in 2025 – the first decline in at least four years. According to Gallagher’s March 2026 Insurance Market Update, both IAG and Suncorp reported declines in New Zealand gross written premium, with IAG’s intermediated business falling 10.4% and Suncorp reporting a 5.6% decline.
In health insurance, the Reserve Bank’s May 2026 Financial Stability Report noted the sector was under increased pressure following two years of claims cost inflation and increased utilisation, with firms responding through higher premiums and other policy changes, and with some but not all insurers reporting profitable quarters. In life insurance, FSC data shows annual premiums reached $3.31 billion as at March 2026, up 2.7% year-on-year, even as cover numbers continued to fall across several key products – a dynamic the FSC attributed to pressure on household budgets, changing customer needs, or people reassessing the level of cover they can afford. The backdrop to all three is a shrinking insured population. The share of New Zealand households without insurance rose from 7% in 2022 to 17% in 2025, according to Consumer NZ survey data – a structural trend that a new cost layer affecting all 66 insurers simultaneously does nothing to reverse.
The prudential levy also arrives alongside a restructured FENZ levy that took effect July 1. Motor vehicle levies rose from $9.53 to $25 per vehicle and now apply to third-party cover. Early modelling by the Commercial Insurance Exchange (CIX) suggested approximately 94% of commercial clients would face a FENZ levy increase, averaging 71%. Brokers managing commercial property or fleet-heavy books are already navigating those conversations with clients; the prudential levy extends that cost narrative into 2027.
On the day the consultation opened, New Zealand Banking Association (NZBA) chief executive Roger Beaumont called for the levy to be “appropriate, effective, and well targeted.” The ICNZ, responding at the time of the Budget announcement in May, said it looked forward to engaging with officials “to ensure the approach is effective and proportionate.” No further ICNZ statement specific to the August 11 consultation paper had been issued at the time of publication.
According to NZ Herald, Consumer NZ chief executive Jon Duffy gave the levy qualified support, saying “it seems sensible to put these costs on a highly profitable industry,” while adding there was “potential for these costs to be passed through to consumers.” BDO audit and assurance partner Matt McQueen described the levy as “a catch up rather than an outlier, as it will bring New Zealand into alignment with other jurisdictions overseas.”
The methodology set in this round will govern the levy for at least five years. The calibration of the $30,000 fixed floor – and whether it is set at a level smaller and specialist insurers can absorb without market-exit consequences – is the single most commercially significant question this process must resolve for the broker market. Brokers can submit directly to the RBNZ at [email protected] before October 16. The RBNZ has indicated openness to bilateral meetings and group workshops. Final Cabinet decisions are expected in early 2027, with regulations targeted for June-July 2027.
