How does a painting business tell a contractor from an employee in New Zealand?
You start with the gateway test. Employment New Zealand says a worker is a specified contractor only if they have a written agreement saying they are not an employee, can work for someone else (just not at the same time as your job), can choose when they work or subcontract the work, can turn down extra work without the arrangement ending, and had a real chance to get independent advice before signing. Miss any of those and you move to the common law test, which weighs up control, integration and whether the person is genuinely running their own business.
This matters for a painter because you are not making one decision, you are making it on every site. A subcontracted crew pricing and running their own new build job looks nothing like a sprayer you direct day to day on a strata repaint, and the gateway test was built to separate the two more cleanly than before.
What goes wrong when a painter gets this call wrong on site?
A painter who treats a worker as a contractor because that is how it has always been done, without checking the written agreement or who controls the day, can end up with a relationship that the law sees as employment. IRD's interpretation guideline IG 11/01 looks at exactly this kind of dispute in the painting trade.
In one case the guideline discusses, a painter was given work on a daily basis with detailed work directions, could be redirected between jobs, was expected to hit set criteria such as time taken and paint used, and had to check in with the company when a job finished. The court found he was not in business on his own account, even though he owned his own brushes, because the company supplied the rest of the equipment and controlled how the work was done. A painting business making the same arrangement, assuming the paperwork said contractor so the job was done, can be caught the same way.
Why does misclassifying a painter cost more than a fine?
A wrong call here is rarely just a compliance problem, it is a costing problem. A painting business running subcontracted crews on a new build, an employed sprayer on a strata job, and casual labour for exterior prep is booking each of those costs differently in the accounts, whether it realises it or not.
If the cost of a worker who is really an employee is sitting in the accounts as subcontractor spend, the job can look like it carried a healthy margin when the true labour cost, including the obligations that come with employment, was never fully counted. The business can look profitable on paper while the bank balance tells a different story, and the gap usually traces back to how that one booking decision was made, not to the quote itself.
How do AI agents help a painter keep contractor and employee costs straight?
An AI agent is software that does a job the way you would do it, using your own prices, your own wording and your own rules. For a painter running several crews, an agent can be set to flag a worker against the written agreement and the way that job actually runs, before the cost ever lands in the wrong place in the accounts.
This works because it starts data first: the agent is reading your own job files, your own site allocations and your own pay records, not a memory of how it was done last time. That means the classification question gets asked at the point the job is booked, not months later when the activity statement or the annual accounts show a margin that does not match what is in the bank.
What do painters need to know about health and safety either way?
Whatever the classification, both the painter and the worker usually carry duties under the Health and Safety at Work Act 2015. WorkSafe describes a PCBU, a person conducting a business or undertaking, as having a primary duty of care to ensure, so far as is reasonably practicable, the health and safety of workers and anyone else affected by the work, whether that is a crew on scaffold for an exterior or a spray operator on a commercial fit-out.
A worker under the Act can be an employee, a contractor, a subcontractor, or an employee of a subcontractor, and each still has a duty to take reasonable care of themselves and others. WorkSafe's guide to the contracting chain also notes that a self-employed painter working alone is both a PCBU and a worker at the same time, which changes who is responsible for what on a job site with several trades.

- Interpretation Guideline IG 11/01, IRD's guidance, including a painting trade case, on how the courts weigh control and business ownership.
- Self-employed or employee, IRD's reminder that working conditions, not the label in a contract, decide status.
- Introduction to the Health and Safety at Work Act 2015, WorkSafe's outline of a PCBU's duties regardless of how a worker is classified.

How does Data First Coaching approach this?
Data First Coaching, built by Greg Allan, starts from the painter's own job and pay data through the Trade Business Intelligence, not from a memory of how a crew was booked. It looks at where each worker's cost actually sits across current jobs, whether that lines up with how the arrangement really runs, and where the gap between gross profit and what lands in the bank first appears. Greg's own rule on working with other trades applies here too: “Don't put screws in if you don't know what's on the other side of it.” The how of setting this up is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member who joins it open minded and willing to share.
