How does a demolition business tell a contractor from an employee in New Zealand?
You work it out from the actual working arrangement on your sites, not from what the contract or the invoice calls the person. Employment New Zealand runs a gateway test first, and if a worker doesn't meet every part of it, a common law test takes over, looking at intention, control versus independence, integration into the business and the economic reality of the job, according to Employee or contractor?. For a demolition contractor running strip-out, structural and asbestos removal work side by side, that test gets applied separately to every person on the crew, not once to the whole business.
Your excavator operator, your site labourer doing soft strip, your licensed asbestos removalist and your truck driver carting waste to tipping can all sit differently. One might be a permanent employee on wages, another a specified contractor with a written agreement, another a subbie running their own operation under schedular payments. The label you've always used for the role isn't what decides it.
Why does this call matter more to a demolition contractor's margin than its paperwork?
Most demolition businesses run a mixed crew across a single job: a core team on wages for the structural and soft strip work, a licensed asbestos removalist brought in job by job, an excavator operator, and a truck driver handling tipping and recycling who might be on wages or invoicing as a subbie. When a worker's status is wrong, or just unclear, the cost of that person often lands in the wrong place in the numbers.
A wage cost sits in cost of sales against the specific job: the strip-out, the removal, the structural pull-down. A contractor invoice can get coded the same way, or it can drift into overhead if nobody's watching closely, and from there it quietly erodes the gap between the margin quoted on the permit application and the margin that actually lands once the tip fees, the bin hire and the crew are all paid. The business can look busy and still be losing ground on every job, because the leak isn't in the quote, it's in how the people doing the work get booked.
What goes wrong on site when responsibility isn't clear before the job starts?
A demolition site carries real risk: hazardous material like asbestos in the ceiling or the cladding, dust drifting toward the neighbour's fence line, machinery moving near a live structure, salvage material being pulled before the pull-down starts. WorkSafe New Zealand treats everyone carrying out work for the business as a worker, including employees, contractors, subcontractors and the employees of contractors, according to Working at height in New Zealand.
That means who directs the work, who carries the risk and who is accountable if something goes wrong on site needs to be settled before the asbestos removalist or the truck driver turns up, not worked out afterwards. A demolition contractor who hasn't been clear about whether a subcontracted specialist is being directed like an employee, or left to run their own patch of the job, is exposed twice over: once on the employment test, and once on who answers for site safety if the council or a neighbour raises a complaint.
How do you work through the tests for your own crew?
A demolition contractor doesn't need to run this test from memory on every job once the thinking is clear. You look at who sets the hours, who can send someone else to do the job, who decides the quality and amount of work required, and whether the person is genuinely running their own business risk rather than just working under your direction. Inland Revenue's interpretation guide says the fundamental test asks whether the person engaged is in business on their own account, according to IG 16/01: Determining employment status for tax. Inland Revenue's plainer guidance says there's no single test, the conditions actually worked under decide the status, not the title on the contract, according to Self-employed or employee.
Inland Revenue's guide for new employers describes a contractor simply as someone who works for the business but isn't an employee, who usually runs their own operation and invoices for the work, according to First-time employer's guide. If a worker is paid as a contractor through schedular payments, the business doesn't deduct KiwiSaver, student loan repayments or ACC levies, according to Tax schedular payments and file employment information; the contractor is invoiced directly for ACC, according to IR330C tax rate notification for contractors.

How does getting this right change what lands in your job costings?
You get to make the employee-versus-contractor call on purpose, against the capacity you actually carry across your demolition jobs, rather than out of fear of commitment or just doing what's convenient this month. If the excavator work or the asbestos removal is steady enough to fill a wage, that's a different decision to bringing someone in job by job, and it changes which column that person's cost sits against every quote you've won.
Keeping that straight by hand, every pay run, every invoice, every job, is exactly the non-billable work that eats an owner's week. AI agents, which is software that does a job the way you would, with your prices, wording and rules, can carry that booking work so a wage or a contractor invoice always lands against the right job and the right line, the same way every time. AI agents can also flag early if a job's quoted margin is drifting, rather than the owner finding out once the job's finished. That's data first: the decision about a role, and the record of what it cost, comes from how the business actually runs, not from memory at the end of the quarter. For a New Zealand demolition contractor, that's the difference between a quoted margin that survives to the bank and one that quietly disappears into overhead.

How does Data First Coaching approach this?
Data First Coaching starts from the demolition business's own job and pay data through the Trade Business Intelligence, not from a general checklist. It looks at where each crew member's cost actually sits against each job, whether wages or contractor invoices, and checks that against the capacity the business is really carrying before any role gets reclassified. Greg Allan's teaching on hiring is blunt about the order: “you employ and then fill the capacity”, rather than the other way round. The how of working through this for a specific demolition contractor's crew is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member and the place is built for owners who are open minded, innovative and willing to share what they learn.
