Misclassifying a worker as an “independent contractor” when they are legally an employee is one of the most expensive and common mistakes employers make across New Zealand and Australia.
The consequences can be huge.
Backpay. Holiday pay. Leave entitlements. Penalties. Tax liabilities. ACC or workers’ compensation issues. Unfair dismissal claims. Personal grievances. Damaged culture and reputation.
And here’s the kicker:
It doesn’t matter what you call someone. It matters what the law says they are.
A contractor agreement does not make someone a contractor.
A GST number does not make someone a contractor.
An ABN does not make someone a contractor.
Even if the worker agrees to be a contractor, the law can still decide they’re an employee.
Both NZ and Australia use multi-factor legal tests to determine the real nature of the relationship.
Here’s the practical, plain-English guide you need.
The 5 Key Legal Tests for Contractor vs Employee (NZ + AU)
Courts, the Employment Relations Authority, MBIE, Fair Work and the ATO all look at similar factors — and no single factor decides the outcome. It’s the overall picture that matters.
1. CONTROL — Who actually calls the shots?
This is often the biggest indicator.
Ask:
- Who decides how the work is done?
- Who decides when and where the work is done?
- Does the person work under supervision?
- Are they accountable to a manager?
Indicators of an employee:
- set hours
- required presence in the workplace
- direct supervision
- detailed instructions
- performance reviews
- approval needed for leave
Indicators of a contractor:
- freedom in how work is completed
- ability to set their own schedule
- autonomy in methods and tools
- works without supervision
If you micromanage or direct their work heavily, they’re likely an employee — even if the contract says “contractor.”
2. INTEGRATION — Are they part of the organisation?
Ask:
- Do they look and function like your staff?
- Are they embedded in the team?
- Do they represent the company?
- Attend team meetings?
- Use company systems?
Indicators of an employee:
- appears in org charts
- uses company email
- attends staff meetings
- wears a uniform
- included in rosters
- works ongoing, not project-to-project
Indicators of a contractor:
- works for multiple clients
- brings their own branding
- operates independently
- completes specific tasks then moves on
If someone looks like part of the furniture, they’re probably an employee.
3. ECONOMIC REALITY — Who takes financial risk?
Contractors are mini-businesses. Employees are not.
Indicators of an employee:
- paid hourly/salary
- paid regardless of profit or loss
- no financial risk
- equipment provided by employer
- cannot subcontract work
Indicators of a contractor:
- invoices for work
- responsible for tax/GST/ABN
- provides their own tools/equipment
- carries their own insurance
- can subcontract or outsource
- takes genuine profit/risk
If the worker can’t make more money through efficiency or take a financial loss, they’re likely an employee.
4. INTENTION — What did both parties intend?
YES, intention matters…
…but NO, intention does not override the law.
A contract saying “you are a contractor” is only one piece of the puzzle.
Courts look at:
- what was written
- what was said
- what was actually happening
If the practical reality contradicts the contract, the reality wins.
5. THE NATURE OF THE WORK — Is it a core part of the business?
Ask:
- Is this work essential to what the business does?
- Could the business function without it?
- Is the work ongoing and regular?
Indicators of an employee:
- they perform key daily tasks
- work is needed permanently
- they are part of the primary service delivery
Indicators of a contractor:
- niche, specialist or one-off expertise
- project-based
- not part of everyday operations
Example:
A café hiring a contractor barista? High risk.
A café hiring a contractor electrician? Low risk.
NZ vs Australia: key differences
New Zealand
- Focus is on the “real nature of the relationship.”
- Strong emphasis on control and integration.
- Holidays Act makes misclassification extremely costly.
- ERA cases use multi-factor balancing tests.
Australia
- Recent High Court decisions focus heavily on contract terms if the contract reflects the true relationship.
- However, sham contracting provisions still apply.
- Casuals who work regular hours may be deemed permanent.
- Fixed-term and contractor misuse can trigger Fair Work claims.
The fundamentals are nearly identical: labels don’t matter — reality does.
Common employer mistakes (ANZ-wide)
- calling someone a contractor “for flexibility”
- using contractors to avoid leave entitlements
- giving contractors fixed rosters
- requiring contractors to ask permission for time off
- treating contractors like employees during performance issues
- renewing contractor arrangements endlessly
- writing contracts that don’t reflect actual practice
One HR Unlocked client discovered this the hard way:
“We treated our contractor like an employee — turns out legally she was one. HR Unlocked helped us fix it before it became expensive.”
These mistakes are avoidable.
How to fix contractor risk
Here’s the HR Unlocked approach:
1. Do a classification audit
Check each worker against the five tests.
2. Update agreements to match reality
Contracts must reflect how work is actually done.
3. Adjust working practices
If the contract says “contractor,” lead like they are one.
4. Stop rolling contractors indefinitely
Move long-term contractors to proper employment agreements.
5. Document your decisions
This matters if a complaint arises.
A quick checklist: Is this person really a contractor?
If you answer yes to these five questions, you’re on solid ground:
- Do they control their work?
- Can they subcontract?
- Do they supply tools/equipment?
- Do they take financial risk?
- Are they independent from the business?
If not… they’re probably an employee.
The bottom line
Classifying someone as a contractor doesn’t make them one.
The law does.
Across New Zealand and Australia, the safest approach is to:
- match the agreement to the real nature of the job
- use contractor arrangements only when genuinely appropriate
- avoid long-term or pseudo-employment relationships
- assess regularly
- prioritise transparency and fairness
A correct classification protects your business, reduces legal risk, and builds trust.
