Find out about the most significant reforms to the Health and Safety at Work Act 2015 (HSWA) which is anticipated to come into effect by 24 September 2026. Our health and safety experts explain how the proposed Health and Safety Amendment Bill (Bill) is intended to shift how businesses are required to identify and manage risks — with a focus on “critical risks”, reducing unnecessary compliance costs, an expansion of approved codes of practice, and clearer guidance for duty holders.

This change of focus redirects effort and regulatory attention towards the kinds of risks that lead to death, serious injury, notifiable incidents and occupational disease.
A “critical risk” will be defined as:
The Bill will differentiate between small PCBUs (PCBUs with fewer than 20 workers but with some recognition for staff number fluctuation due to seasonal work) and other PCBUs.
Small PCBUs must:
These material duties include those set out in sections 36 to 43 of the HSWA, as well as the duty to provide information, supervision, training and instruction, and the duty to provide personal protection equipment and to ensure it is worn.
This change arguably responds to the recent Maritime NZ v Gibson case, where, after the death of a port worker, the former CEO of Ports of Auckland was successfully prosecuted under the HSWA for failing to exercise due diligence.
Under the Bill:
ACOPs will no longer need to be developed solely by WorkSafe. Any business organisation may draft a code of practice for WorkSafe review and Ministerial approval.
If a PCBU complies with an approved ACOP, it will be treated as having complied with its relevant HSWA duties.
This change is expected to:
Where a PCBU is subject to:
then compliance with the other Act will satisfy the HSWA duty — unless a HSWA regulation imposes specific duties as well.
The Bill introduces an exception or PCBUs who manage or control a workplace in an earthquake-prone building.
Where a workplace is in a building that has been properly assessed under the Building Act 2004 as earthquake-prone and the building owner is complying with its obligations under that Act in regard to the earthquake-prone building, a PCBU will not need to take steps in relation to seismic risk (such as evacuating the building) unless an emergency is occurring that affects the building.
This amendment is intended to provide certainty for landowners who are reluctant to allow recreational users to access their land.
The Bill limits liability for PCBUs who manage and control land that includes open space lawfully used for recreational purposes unless:
The Bill also proposes amendments to the WorkSafe New Zealand Act 2013 to reprioritise WorkSafe’s (and other designated regulators’) functions.
Regulators’ main functions will now be:
This change aims to refocus WorkSafe and other regulators on education and practical guidance, rather than enforcement.
Businesses should expect:
The Bill has only had its first reading and must still pass through the parliamentary process, including select committee stage. We will keep you informed of progress with the Bill, and any changes that are made to the proposed reforms.
