In June 2025, the New Zealand Government unveiled a sweeping amendment to the country’s work health and safety regime, marking the most significant shift in WorkSafe New Zealand’s mandate since the Health and Safety at Work Act (HSW Act) came into force in 2016. The reforms, part of a broader government push to modernise regulation and reduce compliance burdens, aim to sharpen WorkSafe’s focus on “critical risks”—those with the potential to cause death, serious injury, illness, or catastrophic failure—while transforming the regulator’s culture from punitive enforcement to proactive partnership and guidance.

This article provides a detailed overview of the WorkSafe amendment, its key provisions, the historical context that led to these changes, and what businesses, workers, and the wider public can expect in the years ahead.

1. Background: Why Reform Was Needed

The State of Work Health and Safety in New Zealand

New Zealand’s work health and safety record has long lagged behind many OECD nations. The Pike River mine disaster in 2010, which claimed 29 lives, was a watershed moment, exposing systemic failures in regulation, enforcement, and workplace culture. The subsequent Royal Commission and Independent Taskforce led to the creation of WorkSafe New Zealand and the introduction of the HSW Act in 2016, which placed greater responsibility on businesses (“duty-holders”) to manage risks and empowered WorkSafe as the primary regulator.

Challenges and Criticisms

Despite progress, persistent challenges remained:

Inconsistent enforcement: Businesses reported variability in inspector decisions and guidance, leading to confusion and uncertainty.
Compliance burden: Many small and medium enterprises (SMEs) felt overwhelmed by what they saw as a “tick-box” approach, with excessive paperwork and a focus on minor risks rather than the most serious hazards.
Punitive culture: Some sectors viewed WorkSafe as an enforcer to be feared, rather than a partner in improving safety.
Resource allocation: Critics argued that WorkSafe was spread too thin, addressing every conceivable risk rather than concentrating on the most dangerous ones.

Calls for Change

Public consultations and industry feedback in 2024 made it clear: businesses and workers wanted a regulator that provided clear, consistent guidance, prioritised the biggest risks, and worked collaboratively to improve safety outcomes.

2. The 2025 WorkSafe Amendment: Key Takeaways

A. Refocusing on Critical Risk

Main Objective Redefined:
The amendment changes WorkSafe’s legislated objective from “promoting and contributing to a balanced framework for securing the health and safety of workers and workplaces” to a sharper focus on managing “critical risks”—those with the potential to cause death, serious injury, illness, or catastrophic failure.

Why It Matters:
This shift means WorkSafe will no longer expect businesses to address every possible risk with equal intensity. Instead, the regulator and businesses alike will concentrate their time, resources, and expertise on the hazards that matter most.

B. Principal Functions Clarified

Guidance Over Enforcement:
The amendment clarifies that WorkSafe’s principal functions are to provide guidance, information, codes of practice, and safe work instruments, as well as to monitor and enforce compliance. Enforcement remains important, but is balanced with a stronger emphasis on supporting and educating duty-holders.

Third-Party Authorisations:
WorkSafe’s role in authorising and monitoring third parties (such as certifiers and training providers) is also codified, ensuring quality and consistency across the system.

C. Legislative and Funding Changes

Health and Safety at Work Reform Bill:
The changes will be enacted through an omnibus bill amending both the HSW Act and the WorkSafe New Zealand Act 2013. The bill has been given a category five priority in the 2025 legislative programme, signalling its importance.

Restructured Funding Model:
WorkSafe’s appropriation will be split into clear categories:

Supporting practice (guidance, advice, inspections)
Enforcing compliance (investigations and enforcement)
Authorising and monitoring third parties
Energy safety function

This aims to improve transparency and ensure resources are directed where they have the greatest impact.

D. Ministerial Direction and Accountability

The Minister for Workplace Relations and Safety will use new and existing levers to set clear expectations for WorkSafe, aligning its work with government priorities and ensuring feedback loops with businesses and workers.

E. Cost and Regulatory Impact

The reforms are fiscally neutral—no increase in overall funding, but a reallocation of resources. The government expects the cumulative effect to be a reduction in compliance costs for business, without compromising worker safety.

3. Implementation: How Change Will Happen

Immediate Steps

Ministerial expectations have already been communicated to WorkSafe, with the agency expected to begin shifting its culture and focus ahead of the formal legislative changes.
Feedback loops will be established to ensure consistency in guidance and enforcement across regions and industries.

Legislative Timeline

The Health and Safety at Work Reform Bill will be introduced and progressed through Parliament in 2025, with changes expected to come into force in stages from late 2025 into 2026.

Practical Impact

For Businesses: Less “red tape” and more clarity on what risks must be prioritised. Guidance and codes of practice will be updated to reflect the new focus.
For Workers: A renewed focus on the most serious risks means greater protection where it matters most, but also an expectation of active engagement in managing safety.
For WorkSafe: Inspectors and staff will be trained and resourced to provide consistent, high-value guidance and to target enforcement at critical hazards.

4. Historical Data: New Zealand’s Health and Safety Journey

Key Milestones

2010: Pike River mine disaster prompts national soul-searching.
2013: WorkSafe New Zealand established as the new regulator.
2016: Health and Safety at Work Act comes into force, introducing a risk-based, duty-holder approach.
2016–2024: Gradual improvement in workplace fatality and serious injury rates, but progress slows and compliance burdens grow.
2024: Public consultation reveals widespread dissatisfaction with regulatory culture and effectiveness.
2025: Major amendment to refocus WorkSafe and the HSW Act on critical risk.

Workplace Fatality and Injury Data

2010: 102 workplace fatalities (all sectors)
2016: 69 workplace fatalities
2023: 51 workplace fatalities (provisional)
Serious injuries: Down from 3,200 in 2010 to 2,100 in 2023 (per ACC claims data)

While the trend is positive, New Zealand’s fatality rate remains higher than Australia and the UK, especially in high-risk sectors like agriculture, forestry, and construction.

5. Sector Reactions: Business, Worker, and Regulator Perspectives

Business Community

Industry groups such as the Employers and Manufacturers Association (EMA) have welcomed the changes as a “modern, supportive step,” praising the move away from a punitive culture and toward practical, risk-based guidance. SMEs, in particular, expect relief from excessive paperwork and more relevant, targeted support.

Worker Representatives

Unions and worker advocates have been cautiously optimistic. They support the focus on critical risks but stress that enforcement must remain robust, especially in sectors with vulnerable or precarious workers. There is a call for ongoing monitoring to ensure that the shift does not lead to complacency or under-resourcing of enforcement.

WorkSafe New Zealand

WorkSafe’s leadership has acknowledged past inconsistencies and welcomed the clarity provided by the new legislative objectives. The agency is investing in staff training and digital tools to deliver on its new mandate.

6. International Comparisons and Best Practice

New Zealand’s move to a “critical risk” focus aligns with best practice in jurisdictions such as Australia, the UK, and Canada, where regulators have shifted from blanket compliance to targeted interventions. Evidence from these countries suggests that prioritising high-impact risks leads to better safety outcomes and more efficient use of resources.

7. Key Takeaways for Businesses and Workers

What’s Changing

Focus on critical risk: Businesses must identify and manage the hazards most likely to cause death or serious harm.
More guidance, less fear: WorkSafe will provide clearer, more consistent advice and support, with enforcement targeted at the most serious breaches.
Less paperwork: Compliance requirements for low-risk hazards will be streamlined.
Feedback and accountability: Businesses and workers will have more opportunities to provide input and hold the regulator to account.

What’s Not Changing

Duty of care: Employers are still legally responsible for providing a safe workplace.
Worker engagement: Workers remain central to identifying and managing risks.
Enforcement: Serious breaches, especially those involving critical risks, will still be met with strong enforcement action.

8. The Road Ahead: Challenges and Opportunities

Challenges

Cultural change: Moving from a punitive to a partnership model will require sustained effort, training, and leadership within WorkSafe and across industries.
Consistency: Ensuring that guidance and enforcement are applied evenly across regions and sectors.
Monitoring outcomes: The government and WorkSafe will need robust data and feedback systems to track the impact of the reforms.

Opportunities

Safer workplaces: By focusing on what matters most, New Zealand can accelerate its progress toward world-class health and safety outcomes.
Reduced compliance burden: Businesses can invest more in practical risk management and less in paperwork.
Innovation: A more supportive regulatory environment can encourage innovation in safety practices and technologies.

9. Summary

The 2025 WorkSafe amendment marks a turning point in New Zealand’s approach to workplace health and safety. By shifting the focus to critical risks and transforming the regulator’s culture from enforcer to partner, the government aims to deliver safer workplaces, a more supportive environment for businesses, and a more effective, efficient regulatory system. Success will depend on ongoing engagement, robust monitoring, and a shared commitment to making New Zealand one of the safest places in the world to work.
