NZI has appointed Troy Sexton (pictured, left) as executive manager of Portfolio Performance and Strategy and Kent Chaplin (pictured, right) as head of liability, bringing two senior leaders into its Property and Liability team at a specific point in the New Zealand commercial insurance cycle. Sexton joins on July 20 in a newly created role; Chaplin joins in September. Both appointments are to NZI, IAG's broker-intermediated arm in New Zealand.
The market conditions that frame the hires are specific. IAG reported that NZI's local-currency gross written premium fell 10.4% to $808 million in 1H26, citing challenging market conditions in a softening commercial market while maintaining underwriting discipline. The comparison period shows the direction of travel: in 1H25, NZI's underlying local-currency GWP had risen only approximately 1% to $902 million, already constrained by early soft market conditions. Suncorp's Vero operation reported similar pressure - total New Zealand GWP declining 5.6% in 1H26 with commercial GWP down 10.1%, attributed to the same soft market cycle. New Zealand's commercial insurance market has been softening since Q3 2024, and the broker channel has felt the effect most directly.
In a soft market, underwriting discipline and portfolio governance become more commercially consequential than in a hard market - the decisions that determine which risks to write, at what terms and with what pricing rigour define profitability when rate is working against the book rather than for it. That is the specific context in which both roles read as investments in underwriting capability rather than routine appointments.
Sexton will lead NZI's Property portfolio strategy, performance and underwriting governance, working across underwriting, pricing, product and finance to optimise portfolio outcomes and balance risk and growth. He joins NZI's leadership team from Everest Insurance, where he established and led the company's Property - Asia Pacific business, having previously spent 18 years with ACE and Chubb including as Chubb's chief underwriting officer for Property - Asia Pacific across 12 countries.
Chaplin will lead NZI's end-to-end liability proposition, bringing portfolio strategy, underwriting, claims, distribution and market engagement under a single leadership role - a structure that mirrors the sales-service unification logic increasingly visible across commercial insurance platforms. He brings more than 30 years of experience across insurance, reinsurance, law and specialty markets, most recently as group CEO of Delta Insurance Group, having also served as CEO of Lloyd's Asia Pacific.
Garry Taylor, executive general manager at NZI, described the appointments as a signal of commitment to investing in people and expertise to support brokers and customers for the long term, noting that both Sexton and Chaplin bring deep technical expertise and strengthen NZI's property and liability portfolio capability and commitment to quality decision-making and sustainable growth.
The appointments follow other recent changes. Phil Gibson was appointed CEO of IAG New Zealand in December 2025 and commenced the role in March, joining from Accenture where he was a senior executive advisor. NZI has also deployed additional capacity through two independent underwriting agencies focused on rural and personal lines, using technology-based platforms for distribution and servicing, according to Gallagher.
Statutory liability exposure has shifted alongside the market conditions. Amendments introduced in 2025 increased maximum fines and made Resource Management Act fines uninsurable. Statutory liability typically covers defence costs, but businesses now face greater direct exposure if enforcement action occurs - a development that adds a specific product complexity dimension to the liability leadership role Chaplin is taking on.
Gallagher has warned of a possible profitability tipping point for the New Zealand commercial market within the next six months. For NZI, the combination of a 10.4% GWP decline, a newly elevated statutory liability exposure landscape and a broker channel under soft market pressure makes the timing of the Sexton and Chaplin appointments less coincidental than it might appear.
