New Zealand passes workplace safety reforms with stronger focus on critical risks

New Zealand has passed sweeping reforms to its workplace health and safety laws, introducing a stronger focus on preventing serious workplace harm while simplifying compliance for businesses, according to the Worksafe Mahi Haumaru Aotearoa. 

The Health and Safety at Work Amendment Bill passed its third and final reading in Parliament and is now awaiting formal sign-off by the Governor-General. The changes will come into force on 1 April 2027, giving businesses and other duty holders time to prepare for the new requirements.

The reforms form part of the ACT-National coalition agreement and are intended to create a more practical health and safety system that prioritises the workplace risks most likely to cause death, serious injury or illness.

Key reforms

The legislation introduces a series of changes aimed at making New Zealand's workplace safety framework clearer and more effective. Among the most significant reforms are:

• A clear definition of critical risks, covering hazards that can result in death, serious injury or illness, enabling businesses to prioritise the most serious workplace dangers.

• Stronger Approved Codes of Practice (ACOPs), giving businesses confidence that following an ACOP's risk management processes will meet their legal health and safety obligations for that risk.

• A more proportionate approach for small businesses, allowing them to focus on managing critical risks while continuing to provide essential worker welfare facilities.

• Clearer responsibilities for company directors, with greater emphasis on governance rather than day-to-day operational management.

• Reduced duplication with other regulatory systems to simplify compliance.

• Greater clarity around responsibilities for recreational activities on land.

• Simpler requirements for reporting serious workplace incidents.

• A renewed focus for WorkSafe New Zealand on critical risks, alongside practical guidance and support for businesses ahead of implementation.

Focus on serious harm

Workplace Relations and Safety Minister Brooke van Velden said, "These changes make it clear that the focus should be on preventing serious harm in the workplace.

"This will better protect workers and support a continued reduction in serious workplace injuries and fatalities,” she added.

“At the same time, it frees up businesses to put more of their resources and efforts towards the things that improve their organisation and contribute to economic growth and quality of life for Kiwis, rather than towards compliance for the sake of compliance,”s he also mentioned.

Van Velden said the Government had acted after hearing consistent feedback that the existing health and safety framework had become too complicated.

"For too long, businesses have been dealing with a system that is confusing and difficult to comply with. Rather than making workers safer, it has distracted from the risks that really matter and increased regulatory burden.

"This Bill reflects that this Government is listening to the people on the ground having to deal with our laws day in and day out. They told us change was needed, and we have delivered."

She added that businesses had also sought clearer guidance on meeting their obligations.

"Businesses told us they need clearer, more practical guidance. The Bill clarifies that if a business follows an ACOP's processes for managing a risk, they can be confident they are meeting their health and safety obligations for that risk."

Business welcomes changes

BusinessNZ welcomed the legislation, saying it responds to long-standing concerns from employers, particularly smaller businesses, about the complexity of the existing regime.

BusinessNZ chief executive Katherine Rich said businesses supported strong workplace safety standards but wanted a system that was easier to understand and apply.

"Small businesses support good health and safety. They want to keep their people safe. What they have struggled with is a system that has become unnecessarily complex and difficult to apply in low-risk workplaces."

Rich said the reforms would encourage greater engagement by making compliance more practical.

"When the rules are clearer and easier to understand, businesses are more likely to engage with them. Good health and safety is about understanding real risks, not ticking boxes.

"The best health and safety system is one that businesses understand, workers trust, and that keeps people safe every day."

Implementation begins 2027

The Government said WorkSafe New Zealand will develop guidance, training and support materials over the coming months to help businesses, workers and other duty holders prepare before the reforms take effect on 1 April 2027.

The Government said the amendments strike a balance between maintaining strong protections for workers and creating a simpler, more practical workplace safety system centred on managing critical risks and improving long-term safety outcomes.
