NZ Health & Safety Amendment Act lets small firms (<20 workers) focus on critical risks

NZ Health & Safety Amendment Act lets small firms (<20 workers) focus on critical risks

The Health and Safety at Work Amendment Act 2026 received Royal Assent on 13 July 2026, with the main changes taking effect 1 April 2027. It creates a new 'small PCBU' category for businesses with fewer than 20 workers, who will only need to actively manage 'critical risks' (those likely to cause death or serious injury/illness) rather than exhaustively documenting every hazard. Businesses that follow an approved code of practice are treated as compliant and shielded from enforcement on those matters.

Why this matters for founders

Founders running lean teams under 20 people can cut health-and-safety paperwork by scoping obligations to a defined list of critical risks and adopting an industry-approved code of practice as a compliance safe harbour. Use the runway to 1 April 2027 to map your critical risks now rather than maintaining sprawling generic risk registers.
