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

What goes wrong when an air conditioning business gets employee status wrong?

Getting employee status wrong can leave a trade business owing back pay, holiday pay and PAYE tax it never set aside, plus penalties from Inland Revenue and Employment New Zealand. An HVAC technician running split system installs, ducted jobs and a maintenance contract book carries this risk in every casual arrangement that looks like a quick fix on paper but runs like a job for months on site.

An HVAC technician who calls in extra hands for a commercial ductwork job through summer peak, or hands a run of warranty callbacks to a mate with a van and a refrigerant handling licence, can end up with a worker treated as a contractor on the invoice but managed like staff on site. Inland Revenue and Employment New Zealand do not read the invoice. They look at who sets the hours, who owns the gauges and recovery unit, and who carries the loss if a compressor fails after commissioning.

Why does this get confusing for an HVAC technician who uses subbies on install days?

It gets confusing because the same tradesperson can be a genuine contractor on one job and look like an employee on the next for an HVAC technician who keeps changing crews, depending on how much control is kept over the day. A refrigeration tradesperson who sets their own hours, supplies their own tools and refrigerant, and can turn down a job is a different legal picture from a technician who fronts up to every ducted install at a set time in the business's van.

The confusion often grows during the busiest stretch of the year, when an air conditioning business books a run of split system installs and heat pump jobs back to back and reaches for whoever is available. A written agreement calling someone a contractor does not settle the question if, in practice, the business decides the hours, supplies the condenser units and controls how the ductwork gets run. The actual working arrangement, not the label on the paperwork, is what a dispute or an audit looks at.

What tests does New Zealand use to decide if your installer is a contractor?

You check the arrangement against two tests Employment New Zealand sets out. Employee or contractor? explains that you first use the gateway test, and if the worker meets every criterion in it, they are a contractor. If they do not meet all of the criteria, you then use the common law test to check their status properly.

The gateway test looks at things like whether there is a written agreement stating the person is an independent contractor, whether they can work for other businesses, whether they can choose when to work, whether they can subcontract the job to someone else, and whether they had a real chance to get independent advice before signing. The gateway test came into law on the twenty-first of February, twenty twenty-six, and it is not retrospective, so an air conditioning business with an arrangement that started earlier uses the common law test for the period before that date, and both tests from that date onward, according to Employee or contractor?.

What does Inland Revenue check that is separate from Employment New Zealand's test?

Inland Revenue asks its own set of questions, because tax status and employment status are assessed separately even though they usually land the same way for a given installer. Self-employed or employee says there is no single test, and the working conditions actually agreed, not the label on an invoice, decide the answer for tax purposes.

Inland Revenue's guidelines ask whether the worker supplies the major tools and equipment for the job, such as their own gauges, recovery unit or van, whether they pay for their own training, including renewing their own refrigerant handling licence, whether they decide how the work gets done, and whether they risk their own money in the business, for instance by carrying the cost if a job runs over or a breakdown callout goes wrong. Inland Revenue's interpretation guideline IG 16/01 sets out the intention, control, independence, fundamental and integration tests that apply equally to an HVAC technician and the installer they engage, and its guideline IG 11/01 makes clear that calling someone a contractor does not change their status if the working relationship is really employment.

What should you update in your contractor agreements now?

You review your written agreements and onboarding steps against the Employment Relations Amendment Act 2025, because a series of changes to the Employment Relations Act took effect and the gateway test is one result of them. Employment changes: what you need to know and Employment Relations Act changes take effect today set out what changed and when.

For an HVAC technician juggling service agreements, maintenance contracts and a string of warranty callbacks across different customers, reviewing every subbie arrangement from memory at tax time is exactly the kind of work that gets skipped. This is where a data first approach matters: the real answer sits in who actually worked which job, whose van it was, whose refrigerant went into the system, and who carried the risk, not in what anyone remembers months later. AI agents, which are software that does a job the way the owner would, with their own prices, wording and rules, can hold that detail against the current test as each job is booked, so the owner is not guessing whether the installer on last month's ducted job sits on the contractor side of the line or the employee side.

How does Data First Coaching approach this?

Data First Coaching starts from the actual job and pay data an air conditioning business already has, not from a memory of who worked what job last summer. Greg Allan's approach looks first at where contractor and employee lines blur, often around casual installers brought on for a ducted job or a run of warranty callbacks, because that is usually where the real cost sits, not in the paperwork itself. AI agents can be shaped to hold that detail job by job, in the owner's own wording, so the pattern shows up before it becomes a problem. The how of building that is worked through inside the Academy, with members who are open minded, innovative and willing to share what they learn, because the Trade Business Intelligence is powered by every member.
