Who is the PCBU in a cabinetmaking business, and does it apply to a one-person workshop?
If you run the joinery business, whether it is just you on the CNC and bench or you have a small crew doing site measures and installs, you are very likely the PCBU. According to WorkSafe's Introduction to the Health and Safety at Work Act 2015, a PCBU is a person conducting a business or undertaking, and it may be an individual person or an organisation, so a sole trader cabinetmaker carries the same duty as a joinery company with staff.
That duty does not switch off because the business is small or because the owner is the one standing at the panel saw most days. Under HSWA, WorkSafe explains in Working at height in New Zealand that there are four groups with duties under the Act: PCBUs, officers, workers, and other persons at the workplace, which can include a builder's site team, a subbie, or a client walking through during an install.
What is the primary duty of care a cabinetmaker owes, in the workshop and on site?
The primary duty of care means the cabinetmaker must manage risks so far as is reasonably practicable, trying first to eliminate a hazard and, where that is not possible, to minimise it. That is the standard WorkSafe sets out in Appendix 1: Health and Safety at Work Act duties and in the Introduction to the Health and Safety at Work Act 2015.
In plain terms for a joinery business, that duty runs across a workshop that is without risks to health and safety, plant and machinery that is maintained and safe to use, safe systems of work from shop drawings through to install, safe handling and storage of board, laminate, two pack finishes and hardware, and the information, training, instruction or supervision a worker needs to do their part of the job safely. It also covers adequate facilities for anyone working for the business, including access to them. None of this is a once-off checklist signed at the start of the year. It is a standard the business is expected to keep meeting as jobs change, from a flat pack wardrobe run to a full kitchen fit out.
What do the machinery and wood dust rules mean for a cabinetmaking workshop?
A cabinetmaking workshop sits squarely inside WorkSafe's guidance on machinery guarding and wood dust, because CNC routers, panel saws and edgebanders are exactly the plant these pages are written for. WorkSafe's Safe use of machinery page says guards must be constantly maintained, of substantial construction, and kept in position while the machinery is used, and that where access to running machinery is needed there must be written procedures for inspection, repair, maintenance and cleaning.
Wood dust from cutting, sanding and edging board is treated as its own risk. WorkSafe's wood dust guidance, in the wood dust quick guide and the fuller Wood dust: controlling the risks page, explains that a PCBU must eliminate the risk where reasonably practicable and minimise it where it cannot be eliminated, with preference given to controls that protect everyone in the workshop at once rather than relying only on a mask for the person at the sander. Where exposure is routine, the guidance also points to health monitoring for affected workers. For a cabinetmaker who has run the same bench setup for years, this is worth checking against the current pages rather than memory of how the workshop was fitted out when it started.
What duties apply when you have a crew or subbies on an install day?
Install day brings a different set of risks into play, from lifting benchtops and carrying cabinetry up stairs on a renovation to working on a mezzanine or near an open stairwell on a new build. WorkSafe's Working at height in New Zealand page confirms HSWA covers all work-related activities wherever they take place, so the duty follows the crew off the workshop floor and onto the builder's site.
Part of the primary duty of care is engaging workers on health and safety matters that affect them and giving them a real opportunity to take part in improving it, as set out in the guide to New Zealand's key work health and safety law. For a cabinetmaker that can be as simple as talking through the install plan with whoever is on the van before the job, not assuming everyone already knows the site.
What has to be reported to WorkSafe if something goes wrong?
A PCBU must make sure WorkSafe is told about notifiable events arising from the business, which the guide to the Act describes as a death, or a notifiable incident, illness or injury. This duty sits alongside the day to day one of managing risk, and it applies whether the event happens in the workshop or on a client's site during install.
This is general information, not legal, tax or employment advice. Check your own situation with the body named here or a qualified adviser.
How does this sit alongside running a cabinetmaking business day to day?
For most cabinetmakers, health and safety duties live in the same place as quoting, site measures and lead times: somewhere between a folder in the workshop office and whatever gets remembered under pressure. The real cost is not the paperwork itself, it is that it gets done from memory weeks after the job rather than from what actually happened that week on the CNC or on an install.
This is where data first thinking changes the picture. Your own job data, who was on which install, what machinery ran that week, what the workshop looked like on a given day, tells a truer story than trying to reconstruct it later. An AI agent, which is software that does a job the way you would, with your prices, wording and rules, can hold that record as the job moves, rather than leaving it to be rebuilt from memory at the end of the month. A second AI agent doing the same for training records or toolbox talks means the business has something real to point to, not a guess about what was covered.
Where the business is in New Zealand does not change any of these duties, and it does not change how coaching works either. Greg coaches cabinetmakers online across New Zealand and Australia, starting from the owner's own job and finance data rather than a generic checklist written for every trade at once.

How does Data First Coaching approach this?
Data First Coaching starts from the cabinetmaker's own job and workshop data rather than a general safety checklist, because the real picture of risk, who was on the CNC, which install days had a crew on site, what training has actually been covered, sits in the business's own records, not in memory. Greg Allan's Trade Business Intelligence reads that data alongside years of coaching trade businesses to find where a safety gap actually starts, often somewhere quieter than the obvious job. The how, including the systems and the agents built around it, is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member for every member, and the Academy is built for owners who are open minded, innovative and willing to share what they learn.
