If you run a business in New Zealand, you may have heard the word PCBU.

But you might still be wondering:

“Does that actually apply to me?”

Many small business owners think health and safety law is only for big companies.
It’s not.

Under the Health and Safety at Work Act 2015 (HSWA), most businesses are classed as a PCBU (Person Conducting a Business or Undertaking).

In our previous article, “PCBU duties in plain English (and what businesses get wrong most),” we explained what a PCBU is and what the main duties involve.

Now let’s make it practical.

Here are 5 clear signs your business has legal duties under HSWA.

1️⃣ You Run a Business (Even If It’s Just You)

If you are:

• A sole trader
• A self-employed contractor
• A limited company
• A partnership
• A trust running a business

You are very likely a PCBU.

You do not need employees to have duties.

If you are running work for profit (or even regularly), the law usually applies.

Even one-person operations must make sure their work does not harm:

• Themselves
• Other workers
• Clients
• Members of the public

If you are “running the work,” you are probably a PCBU.

2️⃣ You Direct or Influence Other Workers

If you:

• Hire staff
• Use subcontractors
• Direct labour crews
• Control how work is done

You have legal health and safety duties.

You must make sure:

• Risks are identified
• Controls are in place
• Workers are trained
• Work is supervised properly

You cannot say, “They’re experienced, they’ll figure it out.”

Under HSWA, you must take steps that are reasonably practicable to keep people safe.

3️⃣ Your Work Could Harm Someone

Ask yourself:

Could my work cause serious harm if something went wrong?

For example:

• Working at height
• Using chainsaws
• Operating machinery
• Handling chemicals
• Moving vehicles
• Working near the public

If the answer is yes, then you have duties.

The law focuses on real risk — not just paperwork.

If your work has risk, you have responsibility.

4️⃣ You Control a Workplace

If you own, lease, or manage:

• A yard
• A workshop
• An orchard block
• A depot
• A building site
• A packhouse

You likely have extra duties.

When you control a workplace, you must make sure it is safe so far as is reasonably practicable.

That includes:

• Traffic flow
• Housekeeping
• Signage
• Exclusion zones
• Maintenance

Even if contractors are working there, you still have responsibilities.

This links closely to overlapping duties, which we will cover further in future articles.

5️⃣ You Work Alongside Other Businesses

If you work with:

• Principal contractors
• Subcontractors
• Clients
• Other crews

You share responsibility.

Under HSWA, multiple PCBUs must:

• Consult
• Cooperate
• Coordinate

If you assume “someone else is handling safety,” that can create serious gaps.

Shared work means shared duties.

Common Signs You Might Be Unsure

Many business owners say:

“I only have one worker.”
“It’s just casual staff.”
“We’re a small rural contractor.”
“I thought the main contractor handled it.”

Size does not remove responsibility.

Small businesses still have duties.

The good news is this:

You do not need a massive 200-page safety manual.

You need:

• Clear risk controls
• Simple procedures
• Training evidence
• A working system

In our article “PCBU duties in plain English (and what businesses get wrong most),” we break down exactly what those duties look like in real life. If you haven’t read it yet, start there.

Quick Self-Check: Are You a PCBU?

If you answer “yes” to any of these, you likely have duties under HSWA:

• I run a business or contracting service.
• I control how work is done.
• I manage a workplace or yard.
• My work involves real risk.
• I work alongside other contractors.

If you answered yes to even one, you should understand your obligations.

Why This Matters

Being a PCBU is not about fear.

It is about:

• Protecting workers
• Protecting the public
• Protecting your business
• Protecting directors

Ignoring PCBU duties does not make them go away.

But understanding them makes them manageable.

What Should You Do Next?

Start simple:

1. Identify your top risks.
2. Check if controls are in place.
3. Make sure workers are trained.
4. Review how you manage contractors.
5. Document what actually happens.

🌍 A Note for Businesses Outside New Zealand

While this article references the Health and Safety at Work Act 2015 (HSWA) in New Zealand, the principle of managing risk so far as is “reasonably practicable” exists in many countries.

Australia, the UK, Canada, and several other jurisdictions use very similar risk-based frameworks.

The legal wording may change.
The expectations may vary slightly.
But the core idea remains the same:

Identify the risk.
Assess the level of harm.
Apply proportionate controls.
Document your reasoning.

If you operate outside New Zealand, you can still apply this structured approach — simply align it with your local legislation.
