Key takeaways

• Apply New Zealand's legal tests by evaluating control, integration, and intention rather than relying solely on written contracts, as courts examine the real working relationship to determine if someone is truly an employee or contractor.
• Assess worker classification using practical factors like whether they provide their own equipment, work for multiple clients, set their own hours, and handle their own tax obligations, as these indicate genuine contractor status.
• Recognise that misclassifying workers can result in significant penalties including back-pay for wages and leave, unpaid PAYE and ACC levies, plus legal costs and reputational damage.
• Choose the right worker type based on your business needs, understanding that employees offer loyalty and availability but require ongoing commitments, while contractors provide flexibility and specialist skills at higher hourly rates.

Understanding the difference between employees and contractors

How you classify your workers affects their rights, your obligations, and your compliance requirements. Getting it wrong can lead to penalties, so it's worth understanding how to distinguish them from the start.

What is an employee?

An employee is a worker whose job you define and direct. You control what they deliver and how they do it. While employees might have some flexibility (like choosing their hours), you have the right to manage and supervise their work.

Employees are part of your business. They typically work set hours, use your tools, and follow your processes.

What is a contractor?

A contractor (also called an independent contractor) is a person in business on their own account. You hire them to complete specific tasks or projects without permanently employing them.

You specify the results you need, but contractors control how they do the work. They typically set their own hours, use their own equipment, and may work for multiple clients.

How New Zealand law determines worker status

New Zealand has specific legal tests to determine whether someone is an employee or contractor. These tests look at the real nature of the working relationship, not just what's written in a contract.

The Employment Relations Authority and courts test several factors together. No single factor is decisive on its own. Employment New Zealand provides detailed guidance on the difference between employees and contractors.

The gateway test

This initial test asks if the person is working for a 'person conducting a business or undertaking' (PCBU). If they are, they could be an employee, and further tests are needed to clarify their status.

Control and independence test

This test looks at who has control over the work. An employee is usually directed on how, when, and where they work. A contractor has more independence and controls their own methods.

Integration test

This considers how integrated the worker is in your business. If they are a core part of your operations, they are more likely an employee. A contractor is typically an accessory to the business, providing services as needed.

Intention of the parties

This test looks at what both you and the worker intended the relationship to be. A written agreement is important, but it must reflect the reality of the situation to be valid.

Eight questions to help you classify workers correctly

These practical questions help you apply New Zealand's legal framework to your specific situation. Work through them to get a clearer picture of whether your worker is an employee or contractor.

1. Is the person's work an integral part of your company's business?

Why it matters: Workers whose roles are essential to your core business operations are more likely to be employees. If you couldn't run your business without this type of work being done, that points toward employment.

Employee indicator: The work is central to what your business doesContractor indicator: The work is supplementary or a one-off project

2. Does the individual have a significant impact on the company's profits?

Why it matters: Workers who directly affect your profitability through their ongoing work are typically more integrated into your business structure.

Employee indicator: Their work directly drives your revenue or reduces costsContractor indicator: They complete discrete projects with defined outcomes

3. How does a worker's investment in the company compare to yours?

Why it matters: Contractors typically invest in their own business by providing their own tools, equipment, and resources. Employees use what you provide.

Employee indicator: You provide the tools, equipment, and workspaceContractor indicator: They supply their own equipment and cover their own business costs

4. Does the work require a special skill set?

Why it matters: Contractors often provide specialist expertise that your business doesn't have in-house. However, skill level alone doesn't determine status.

Employee indicator: The skills are common and the worker could be easily replacedContractor indicator: They bring unique expertise and market their services to multiple clients

5. What degree of control does the worker have?

Why it matters: Control is one of the most significant factors in classification. The more control you have over how, when, and where work is done, the more likely the worker is an employee.

Contractor indicators:

• setting their own hours and schedule
• choosing where they work
• deciding how to complete the work
• working toward a specific end date or deliverable

Employee indicators:

• following set hours or rosters
• working at your premises
• following your processes and procedures
• ongoing work with no defined end point

6. Does the person provide regular and written progress reports to the company?

Why it matters: The nature of reporting and supervision indicates the level of integration with your business.

Employee indicator: You supervise their work directly and they report to a managerContractor indicator: They provide progress updates and invoices at agreed intervals, with less day-to-day oversight

7. Does the person make their own self-employment deductions?

Why it matters: Tax obligations differ significantly between employees and contractors.

Employee indicator: You deduct PAYE, KiwiSaver, and ACC levies from their payContractor indicator: They handle their own tax returns and ACC cover, and according to the IRD, must register for GST if their turnover was over $60,000 in a 12-month period.

8. Does the person have more than one client?

Why it matters: Contractors are in business for themselves, which typically means working for multiple clients. Exclusivity can suggest employment.

Employee indicator: They work exclusively for your businessContractor indicator: They have multiple clients and actively market their services to others

If you're still unsure after working through these questions, talk to your accountant, lawyer, or an employment specialist. Getting it right from the start saves time and money.

Choosing the right type of worker for your business

Once you understand what the law requires, you can think about what works best for your business. Both employees and contractors have advantages and trade-offs.

Most business owners want to manage costs, but the cheapest option isn't always the right one. Consider your workflow, growth plans, and the type of relationship you need with your workers.

Benefits of hiring employees

Employees typically commit to your business long-term. This brings several advantages:

• Business knowledge: They learn how your business works and can do their job without constant direction
• Predictable costs: Wages are often lower than contractor rates because employees have job security and benefits
• Availability: They're there when you need them, even when things get busy
• Business continuity: You can take time off knowing someone is keeping things running

What to consider when hiring employees

Taking on employees comes with ongoing responsibilities:

• Training and developing staff: You're responsible for developing them professionally and ensuring they have required licences
• Consistent pay: You need to pay wages on time, every time, even during quiet periods
• Cash reserves: Keep enough money aside to cover payroll commitments
• Payroll compliance: You must withhold PAYE, contribute to KiwiSaver, manage what you deduct, and according to IRD guidelines, keep all employment and wage records for at least seven years.
• Employment law: You need to follow minimum wage rules, provide the leave employees are entitled to, and meet health and safety requirements

Benefits of hiring contractors

Contractors offer flexibility when you need specific skills or short-term help:

• Speed: You can bring someone in quickly without a lengthy hiring process
• Specialist skills: Access expertise your business doesn't have in-house
• No training costs: They're responsible for developing their own professional skills
• Flexible costs: No salary to commit to, no benefits or leave to pay
• Simple exit: If things don't work out, you're not obligated to continue

What to consider when hiring contractors

Contractors aren't the right fit for every situation. Keep these factors in mind:

• Higher hourly rates: You typically pay more per hour or day than you would for an employee
• Less loyalty: They're running their own business and may prioritise other clients
• Limited control: You specify outcomes but can't dictate how they work
• Availability: They may not be available when your workload increases
• Finding replacements: You might need different skills for your next project
• No on-site presence: They often work remotely, which can limit how well you collaborate

What happens if you misclassify a worker

If you misclassify a worker, your business could face serious problems. If the Employment Relations Authority later finds that someone you called a contractor is actually an employee, you may face financial penalties and back-payments.

Penalties and legal outcomes

If a worker challenges how you classified them, the Employment Relations Authority can rule that they're actually an employee. This can result in:

• Back-pay: You may owe unpaid wages, holiday pay, and other amounts employees are entitled to, such as the 10 paid sick days every employee is entitled to after six months of employment.
• Penalties: Fines for breaching employment law
• Legal costs: Defending a claim takes time and money
• Reputational damage: If workers dispute their status, it can affect your standing with other workers and clients

How this affects tax and ACC

IRD may also review how you classified your workers. If they determine someone was an employee, you could face:

• Unpaid PAYE, plus interest and penalties; for example, if an employee hasn't declared their tax code, you're required to deduct PAYE at the non-notified rate of 46.67%.
• ACC levies: Back-paying what you should have contributed as an employer
• GST: Adjusting GST if you claimed it on contractor invoices incorrectly

How to fix it if you misclassified a worker

To address misclassification:

1. Talk to your accountant or lawyer to confirm how to classify the worker correctly
2. Discuss the situation with the worker openly
3. Change the working relationship to the correct status
4. Calculate and pay any outstanding amounts the worker is entitled to
5. Update your payroll and tax records

The sooner you address it, the smaller the liability.

Classifying workers correctly from the start

The difference between contractors and employees can be complex. But getting it right from the start saves you time, money, and stress.

Start by understanding the legal tests, then work through the practical questions for each worker. If you're unsure, talk to your accountant or lawyer before you start working together.

Once you've classified workers correctly, you need the right tools to manage each type. Xero's payroll software handles employee wages, PAYE, and the leave employees are entitled to. For contractors, Xero makes it easy to track invoices and manage payments.

FAQs on contractors vs employees

Here are answers to common questions about hiring contractors and employees in New Zealand.

Are contractors entitled to the same things as employees in New Zealand?

No. Contractors aren't protected by minimum wage rules, and they don't receive paid leave, rest breaks, or KiwiSaver. They're responsible for their own tax, ACC, and business costs.

Can I change a contractor to an employee later?

Yes. If how you work together changes or you realise you classified them incorrectly, you can transition a contractor to employee status. Update your employment agreement, payroll setup, and how you handle their tax accordingly.

How much more does it cost to hire a contractor vs an employee?

Contractors typically charge higher hourly or daily rates than employee wages. However, you don't pay for leave, contribute to KiwiSaver, or pay ACC levies for contractors, so the total cost depends on how much work you need.

What documents do I need for contractors and employees?

For employees: A written employment agreement, completed IR330 tax code form, and KiwiSaver details.

For contractors: A written contractor agreement specifying the work, payment terms, and that they're responsible for their own tax.

What should I do if IRD questions how I classified my workers?

Respond promptly and gather evidence of how you worked together, including contracts, invoices, and details of how they performed the work. Talk to your accountant, who can help you respond to IRD and calculate what you need to adjust.
