How do shopfitters know if someone on a fit-out is an employee or a contractor?
There is no single switch. Employment New Zealand says the first step is the gateway test: if the written agreement says the person is an independent contractor, lets them work for others, lets them choose when they work or subcontract the work, lets them decline extra offers without the arrangement ending, and they had a fair chance to get advice before signing, they can be treated as a specified contractor.
For a shopfitter, that written agreement question comes up constantly. Workshop joiners, install crews, and subbies brought in to cover a retail or hospitality fit-out might all sit under different arrangements on the same job. Employment New Zealand also notes the gateway test only applies from 21 February 2026 and is not retrospective, so existing agreements with install crews or joiners signed before then are not automatically covered by it.
Why does getting this wrong cost a shopfitter margin, not just a compliance headache?
For a shopfitter running joinery in the workshop and install crews on site, the classification question is never only legal. It decides where the labour cost sits in the job, and whether the gross profit on the shop drawing matches what actually lands once the fit-out is handed over.
A tight programme on a commercial fit-out means after hours work, defects to chase before handover, and a project manager pushing the deadline. If a contractor's invoice or an employee's hours are not pinned to the right job, that cost drifts into general overhead instead of against the progress claim it belongs to. The quote looked profitable. The job, once all the labour is properly attributed, often was not. This tends to show up most as a shopfitter grows past doing every install personally and starts mixing contractor joiners with employed crew to cover more fit-outs at once, the point where capacity is being bought from more than one direction and the true cost of each hour needs to be understood, not assumed.
What tests does the law actually use once the written agreement does not settle it?
Beyond the gateway test, Inland Revenue says there is no single test to decide if a worker is employed or self-employed, and simply labelling the arrangement “employment” or “self-employment” will not decide it. It looks at things like whether the worker can get someone else to do the job, pays helpers from their own money, advertises for more work, and on the other side whether they must do the work personally, can be told what to do and when, are paid a set rate, and work at premises the shopfitter decides.
Inland Revenue's interpretation guideline IG 16/01 sets out two further tests examined by the leading authorities: the control test, which looks at the degree of control the business has over how the work is done, and the fundamental test, which asks whether the person is in business on their own account. A high level of control over a joiner or installer supports an employee finding; genuine independence supports a contractor finding.
Where a worker challenges their status, the Employment Relations Authority and Employment Court apply a series of tests under section 6 of the Employment Relations Act 2000, according to a Ministry of Business, Innovation and Employment briefing. Employment status also decides tax treatment, including whether PAYE must be deducted, under Inland Revenue's guideline.

How do you make sure the cost of that joiner or installer actually lands on the right job?
You don't fix a margin problem by getting the legal test right once a year. You fix it by knowing, job by job, what every person on a fit-out actually cost you, whether they were on wages or invoicing you as a contractor, and making sure that figure sits against the right shop drawing before the progress claim goes out.
That is where AI agents can take over the paperwork a shopfitter never has time for between sites. An AI agent is software that does a job the way you would, with your prices, wording and rules, so when a contractor's invoice or a timesheet comes in, it gets matched to the fit-out it belongs to instead of sitting in overhead until someone notices the margin was wrong months later. A second agent can flag, before a variation or progress claim is sent, whether the labour booked against that job actually reflects what was spent in the workshop and on site.
That is data first thinking: the classification question tells you how the person is paid, your own job data tells you whether that cost is actually where it should be. Most shopfitters find the second question is the one that was quietly costing them.
Where can you check the current rules?
- Employee or contractor? from Employment New Zealand, covers the gateway test and when it applies.
- Self-employed or employee from Inland Revenue, covers the employee and self-employed guidelines and tax consequences.
- IG 16/01, Determining employment status for tax purposes from Inland Revenue, covers the control test and the fundamental test.
- MBIE briefing on contracting parties, covers how the Employment Relations Authority and Employment Court apply section 6 of the Employment Relations Act 2000.
How does Data First Coaching approach this?
Data First Coaching does not start with the legal test, because that only tells you how someone is paid, not what they actually cost your jobs. Greg Allan's method, through the Trade Business Intelligence, starts from the shopfitter's own job and finance data to see whether contractor and employee labour is landing against the right fit-out, and where it is drifting into overhead instead. From there it finds where the real problem starts, which is usually earlier than the classification question itself. The how of building that into the business is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member, and the Academy looks for owners who are open minded, innovative and willing to share what they learn.
