On 5 October 2023, the Incorporated Societies Act 2022 came into force, modernising how societies operate. Existing societies were required to reregister under this Act to remain incorporated, with a deadline of 5 April 2026.
To support members in understanding these changes and their implications, IIA NZ established a Constitution and Policy Committee in 2023 to review our Constitution and By-Laws. The revised IIA NZ Constitution was released to all members in late September 2024, and two member-only workshops were hosted to address any questions.
The review period ran from 1 October to 1 December 2024, ensuring we were prepared with a final version for submission at the AGM on 21 May 2025. The Constitution was unanimously adopted at the May 2025 IIA NZ AGM and re-registered with the Incorporated Societies Register shortly thereafter.
