How does a building business tell a contractor from an employee in New Zealand?

What actually decides if a builder's worker is a contractor or an employee?

For a building business, whether someone on the job is a contractor or an employee is decided by the real working relationship, not by what the contract or the invoice calls them. Employment New Zealand checks this using a gateway test first, and if the worker does not meet every criterion, a common law test applies, looking at four legal factors to find the true nature of the arrangement, as set out on Employee or contractor?.

The gateway test looks at things such as whether there is a written agreement saying the person is an independent contractor and not an employee, whether they are free to work for other businesses, whether they can choose when they work or pass the job to someone else, whether they can turn down an extra job without the arrangement ending, and whether they had a proper chance to get independent advice before signing. A labourer who turns up every day under a site supervisor's direction and works the hours they are told looks very different to a subcontractor who prices a slab pour as a fixed price and books their own time around other jobs.

Why doesn't what the contract calls someone settle the question?

Because Inland Revenue, separately from Employment New Zealand, says there is no single test for tax purposes either, and the label in the contract does not decide anything on its own. According to Self-employed or employee, the working conditions actually agreed, whether written down or spoken, are what count.

Inland Revenue's self-employed guidelines ask whether the worker can bring in other people to help without asking permission, whether they pay those helpers themselves, whether they can take on other work at the same time, whether they advertise for more jobs, and whether they wear the cost if a job is left unfinished. The employee guidelines ask the opposite: whether the person has to do the work themselves, whether someone else can direct what and how, whether they are paid a set rate regardless of output, and whether someone else decides the standard of the finished work. A builder running a renovation with one subcontractor pricing a whole stage and another labourer paid hourly under direction can have both answers sitting in the same job.

What should you check before putting someone on as a subcontractor?

Before you treat someone as a subcontractor on a new home or a renovation, check whether the real arrangement matches a contractor rather than an employee, because the tests above look at how the work actually happens, not what you intend to call it. Hiring your first employee says these tests look at the actual work situation, not just what you think the arrangement should be.

If the work is wholly or substantially labour only in the building industry, such as framing or lining, Inland Revenue treats it as a schedular payment under Schedule four of the Income Tax Act 2007, with a standard rate of tax set for each payment, and the worker notifies their rate using form IR330C. That schedular payment process shows how tax is deducted, but it does not by itself decide whether the person is a contractor or an employee under the tests above, so both checks matter on every job, every variation, every fixed price or cost plus contract you write.

What happens if you get this wrong?

Getting it wrong can leave you exposed on tax, on pay and on safety, because the obligations differ depending on which the worker actually is. The IR335 Employer's guide says you need to know whether the people working for you are employees, contractors receiving schedular payments, or self-employed, because the tax rules for employee pay and other deductions differ from contractor schedular payments, and self-employed people generally have no deductions made at all.

Health and safety does not wait for that answer to be settled. Introduction to the Health and Safety at Work Act 2015 says a worker includes an employee, a contractor or subcontractor, and an employee of a contractor, and the business in charge of the work must ensure, so far as is reasonably practicable, the health and safety of all of them, known as the primary duty of care. WorkSafe New Zealand's Business FAQs adds that a self-employed subcontractor must also look after their own health and safety on site. On a frame stage or lock-up with several trades moving through at once, that duty sits with you regardless of how the pay arrangement is labelled.

How can AI agents help you keep this straight, job by job?

An AI agent is software that does a job the way you would, with your prices, wording and rules, and for this question that means it can hold the paperwork that shows how each person on your jobs actually works, not just what the contract says. Instead of trying to remember at tax time whether a subcontractor on last year's extension was paid a fixed price for a stage of work or an hourly rate under your site supervisor's direction, a data first approach starts from your own job costing, progress claims and payment records, because that is where the real working pattern shows up.

AI agents can watch for the pattern that usually causes trouble, such as a person called a subcontractor on the contract who is actually invoiced like an hourly employee every week, or a variation that quietly changes how someone is paid partway through a renovation. Catching that early, from your own numbers, is worth more than being asked the question by Inland Revenue or WorkSafe New Zealand first. Builders coaching with Greg can start this from wherever their business sits in New Zealand, because the coaching works from the data, not from where the office is.

How does Data First Coaching approach this?

Data First Coaching starts from the builder's own job files, payment records and contracts, read through the Trade Business Intelligence, rather than from a description of how the business thinks it runs people. That is usually where the real pattern between contractor and employee shows up, in how a subcontractor is actually paid and directed job to job, not in the title on the paperwork. Greg Allan looks for where that pattern starts, because it is rarely where the owner first assumed. The how, the systems and the checks built from that are worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member, for every member, and that only works with owners who are open minded, innovative and willing to share what they find.
