How does a plastering business tell a contractor from an employee in New Zealand?
A plastering business works out whether someone is a contractor or an employee by looking at the real working arrangement, not the label on the invoice or a text message. Employment New Zealand says the first step is a gateway test, and if a worker does not meet every part of that test, the business then applies a common law test that looks at control, independence, whether the worker is genuinely in business on their own account, and how far they are woven into the day to day running of the crew. See Employee or contractor?.
The gateway test only came into force on the twenty first of February, two thousand and twenty six, and is not backdated, so an arrangement with a stopper or a fixer that started before that date is judged on the common law test for the period before, and on both tests from that date onward, as Employment New Zealand explains in Employment Relations Act changes. For a plasterer who has had the same sheeter coming and going across several renovation jobs for years, that earlier period still gets measured the old way.
Why does this get harder when a plastering crew moves between builders' sites?
Plastering work makes this question genuinely harder to answer than it first looks, because the same person can turn up on a square metre rate for one builder, get paid as crew for a second, and pick up a cornice fixing day here and there for a third. A specified contractor under the gateway test needs a written agreement, the freedom to work for someone else (though not at the same time), the ability to choose when to work or to subcontract the job on, the right to decline extra work without the arrangement ending, and a real chance to get independent advice before signing. See Employee or contractor? for the full list.
A plasterer who texts a stopper on Sunday night with instructions for where to be and what to bring every single week is setting the kind of control that pulls the relationship back toward employee, whatever the paperwork says. Drying time between coats, water damage repairs, and bulkhead work that has to fit around other trades on site all mean a plastering crew's hours are often set by the job itself, not by the worker, which is exactly the control question the common law test asks.
What does Inland Revenue look at once a plasterer is called a contractor?
Inland Revenue cares less about the title and more about what happens to the tax. The IR335 employer's guide explains that payments to employees have PAYE deducted at source, while payments to contractors for schedular activities have withholding tax deducted instead, and a plastering business needs to know which one applies before the first invoice gets paid. See IR335 Employer's guide.
The Tax Technical summary adds that an employee cannot register for GST or charge GST on work done as an employee, while a contractor who is registered has to meet the GST Act's requirements and account for their own tax and ACC earner and employee premiums. See Summary - Tax Technical. Inland Revenue also says plainly that there is no single test for this and the working conditions decide, not the label, in Self-employed or employee. None of this is settled by what a plastering business writes on the quote.
What should you check before you treat a fixer as a contractor?
You check the written agreement, the actual hours and control on site, and the tax setup, before the job starts, not after a dispute lands on your desk. The control, independence, fundamental and integration tests set out in IG 16/01 are the ones Inland Revenue falls back on when a gateway test does not give a clean answer.
If a fixer or sheeter believes the real relationship is employment, they can take the question to the Employment Relations Authority or the Employment Court, as a briefing paper published by the Ministry of Business, Innovation and Employment sets out. See COVERSHEET Minister Hon Brooke van Velden. If you are unsure which test applies to a particular crew member, Inland Revenue says a business can message through myIR or call, per IR335 Employer's guide.

What changes once a plasterer's labour is booked where it actually belongs?
This kind of coaching works online, starting from the business's own job and crew numbers, so a plastering crew spread across New Zealand does not change how it begins. Getting the employment question right matters for compliance, but for a plasterer it also decides whether the margin on a job is real. A fixer paid as crew sits in cost of sales against the square metre rate quoted for that ceiling or that renovation; a genuine subcontract invoiced separately often sits differently, and if that split is wrong, the margin a plasterer thinks a job made is not what shows up once overhead and GST are accounted for. Data first thinking starts from the plastering business's own job costing, not from memory of what a job usually makes, because the real answer changes every time the crew mix changes.
AI agents, which are software set up to do a job the way the owner would, with the owner's own prices, wording and rules, can carry the paperwork that sits around this decision: tracking which written agreements exist, which crew member was booked to which job at what rate, and flagging when a fixer's hours on site start looking more like a permanent spot than a one off subcontract. Picture a plasterer whose site forms, inductions, incident records and new starter paperwork for sheeters and stoppers were scattered across a folder here, a text thread there, and a separate channel for crew messages altogether. The owner built his own system that pulls job information in and brings the forms, the site specific inductions, the incident register and onboarding together in one place, so nothing about who is on site, under what arrangement, gets lost between jobs. AI agents built around that same job data can also flag when a contractor arrangement has drifted into something that looks like employment, before it becomes a dispute instead of a tidy record.

How does Data First Coaching approach this?
Data First Coaching starts from the plastering business's own job costing and crew records, not from a description of how the owner thinks the business runs. Greg Allan looks first at where each crew member's pay actually lands in the numbers, cost of sales or overhead, against what the square metre rate was quoted on, because that is usually where a margin problem starts, long before it looks like an employment question. Greg teaches that “you employ and then fill the capacity”, so the same discipline that tells an owner when to bring someone on also tells them whether that person belongs as crew or as a genuine subcontract. The how of setting this up is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member and works best for owners who are open minded, innovative and willing to share what they learn.
