The New Zealand Financial Markets Authority published a thematic review insights report on how New Zealand insurers have implemented NZ IFRS 17 Insurance Contracts, providing observations intended to support financial statement preparers, audit committees and auditors. The report focuses on insurers’ transition to NZ IFRS 17, which replaces NZ IFRS 4 and applies to reporting periods starting on or after 1 January 2023. It covers the transition approach, use of measurement models, discount rates and risk adjustment for non-financial risk, treatment of onerous contracts, the impact on equity at the transition date, and other implementation decisions, and flags areas for improvement alongside the FMA’s future focus.
