New Zealand insurers are facing three simultaneous regulatory workstreams – a proposed prudential levy, a rewrite of the primary prudential legislation, and a forthcoming Reserve Bank of New Zealand (RBNZ) paper on the sector’s future – converging at a moment of sustained premium pressure. The confluence was on display at the Financial Services Council (FSC) Conference on August 13, where RBNZ Assistant Governor for Financial Stability Angus McGregor outlined the central bank’s regulatory priorities. For brokers, the regulatory calendar has direct commercial implications. The levy’s proposed design falls hardest on smaller and specialist carriers – precisely the insurers that underwrite niche and hard-to-place risks.
The RBNZ prudential levy consultation paper, released on August 11, estimates the levy would recover $209 million over three years. Insurers would account for $81 million of that total, or 39%, with deposit takers picking up $113 million (54%) and financial market infrastructure providers $15 million (7%). The insurance sector’s share translates to approximately $27.3 million annually across an estimated 66 licensed insurers. 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, while one with $10 million in revenue would face roughly $43,749. For the $10 million insurer, the fixed $30,000 component would account for the majority of the proposed levy, illustrating how the flat charge creates a proportionally greater burden for smaller insurers. That asymmetry is where broker exposure concentrates. Smaller carriers bear the highest proportional cost burden, and the RBNZ’s own consultation paper acknowledges that regulated entities “may then decide to pass on some or all of these costs to their customers.”
The prudential levy arrives on top of an existing regulatory cost structure that the Insurance Council of New Zealand (ICNZ) has described as already substantial. The ICNZ’s industry regulations page notes that “significant taxes and levies” — including GST, the NHCover levy, and the Fire and Emergency New Zealand (FENZ) levy – already add to the cost of insurance in New Zealand. ICNZ chief executive Kris Faafoi has stated that taxes and levies already account for around 40% of a home premium.
At the FSC Conference, McGregor addressed the levy’s rationale directly. “It’s very common in other respects across New Zealand in terms of levy funding,” he said, as reported by Interest.co.nz, noting that similar approaches are used in Australia, Canada, Ireland, and the UK. “Fundamentally it’s just about shifting where the money comes from,” he said. The ICNZ, responding at the time of the Budget 2026 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 consultation paper had been issued at the time of publication.
Submissions close at 5pm on October 16, 2026, with Cabinet expected to make final decisions early in 2027. Regulations are targeted for gazetting between June and July 2027, with the levy taking effect in August 2027.
Running concurrently is the review of the Insurance (Prudential Supervision) Act 2010 (IPSA), the legislation that provides the legal framework for the RBNZ’s prudential regulation and supervision of the insurance sector. The RBNZ says the review is intended to modernise insurance regulation and bring it closer to other domestic regulatory regimes and international best practice. Consultation on the exposure draft of the IPSA Amendment Bill has been extended to August 28, 2026, after which the RBNZ will review feedback and report back to the Minister of Finance and Cabinet. Substantive provisions are targeted to commence in 2028, followed by the development of new prudential requirements and the embedding of new supervisory, enforcement and crisis-management frameworks. The proposed amendments would give the RBNZ a wider range of standards and supervisory tools, strengthen its fit-and-proper and enforcement powers, streamline aspects of the approval regime for significant influence transactions, and modernise the framework for insurer distress management.
RBNZ director of prudential policy Jess Rowe said the central bank is seeking technical input from industry. “We’re seeking technical feedback on the Bill to help ensure the changes work in practice and deliver the policy decisions made by Cabinet last year. It will also help us identify and avoid unintended consequences and regulatory gaps,” she said. For insurers, the IPSA amendments represent a substantive shift in supervisory intensity – with consequences for governance, capital, and compliance resourcing through the implementation window to 2028.
McGregor signalled a third workstream at the FSC Conference. The RBNZ plans to publish its work on the future of banking the following month, with McGregor indicating a similar paper on insurance is under consideration. “This aims to provide a deeper understanding of the forces shaping banking globally and their potential implications for New Zealand’s banking sector and the regulatory environment – and we are considering a similar piece on the future of insurance,” he said, as reported by Interest.co.nz. No release date has been confirmed.
McGregor framed the RBNZ’s overall supervisory approach around proportionality – language with direct relevance to how the levy and IPSA amendments will be applied across a sector of highly varied carrier scale. “A fit-for-purpose regime means regulation and supervision that are proportionate, risk-based, evidence-informed, and future-proofed. It also means being disciplined about minimising unnecessary burden on firms and on the system, while remaining clear about the outcomes we need to achieve for financial stability,” he said. He also pointed to open regulator–industry engagement as a mechanism for better supervision outcomes. “Strong relationships help us do that job better. They allow issues to be raised earlier, risks to be better understood and openly discussed, and supervisory action, where needed, to be better targeted and more effective,” he said.
The proposed levy methodology would determine how the RBNZ recovers its prudential regulation costs from regulated entities. For brokers, the proposed $30,000 fixed component and its potential effect on smaller and specialist insurers are among the key commercial questions raised by the consultation. The RBNZ has indicated that it does not intend to consult further on the draft regulations following the current process, and submissions close at 5pm on October 16, 2026.
