Why manufacturing regulations are finally getting an overhaul

Published 6 Aug 2025 | 2 min read

If you run a business that uses machinery, chances are you’ve been tripped up by confusing safety rules.

Machine guarding laws have been in place for years, but they’re now so outdated that compliance has become a guessing game.

Business owners are being told different things by different inspectors about identical equipment setups.

That uncertainty costs time, adds stress, and creates serious risk.

Businesses are stuck between safety and red tape

Across manufacturing, food production, construction, and even agriculture, businesses have spoken out about unclear WorkSafe advice.

Some have upgraded machines or installed new controls based on inspector guidance, only to be told later those same measures don’t meet the rules.

One Auckland business passed inspection, while another in Christchurch was flagged for an identical setup.

Others, like commercial bakeries, have spent millions on upgrades to meet flour dust exposure standards they still can’t consistently comply with.

What’s changing in New Zealand’s machine guarding laws?

The Government is proposing to simplify the machine guarding rules under the Health and Safety in Employment Regulations. These changes are designed to focus on real-world risks, not just theoretical hazards.

What are the new Workplace Exposure Standard (WES) updates in NZ?

WorkSafe is reviewing standards for wood dust, welding fumes, and flour dust. The aim is to ensure these reflect measurable, realistic levels based on international benchmarks.

One rulebook, two inspectors, no clarity

When one machine setup is deemed compliant in one city and non-compliant in another, it shows how much trust has been lost in the system. Even WorkSafe inspectors appear to interpret the law differently.

Some meat processors say that current guarding rules make routine food safety cleaning almost impossible. Businesses are forced to choose between meeting regulatory requirements or staying operational, a choice no one should have to make.

What these changes mean for business owners

Minister Brooke van Velden has confirmed that feedback from Kiwi manufacturers is driving this review. The current machine guarding rules will be replaced with a more flexible, risk-based approach.

Exposure standards for wood dust and welding fumes will be updated, with a review of flour dust limits underway.

The changes are not just for large-scale manufacturers, any business using machinery or working with dust-generating materials could benefit.

These reforms are designed to reflect real workplace risks, reduce compliance costs, and create more consistency in enforcement. They also signal a shift toward smarter regulation that supports safe practices without crushing productivity.

A clearer path forward for NZ employers

These updates offer a rare win for businesses that have long been stuck in the grey area of health and safety law. If implemented well, the changes will let you focus on genuine risk management instead of second-guessing inspectors.

As the Government works with manufacturers to finalise the new rules, it’s a good time to review your current safety systems and stay in the loop.

Clearer guidance, updated standards, and less red tape will help you protect your people and your bottom line, and that’s worth backing.
