What health and safety duties does the owner of a fabrication business have in New Zealand?
As the owner of a fabrication business in New Zealand, you are the PCBU (person conducting a business or undertaking), and that carries what WorkSafe calls the primary duty of care: so far as is reasonably practicable, you must look after the health and safety of your welders and workshop crew, and make sure others your work puts at risk, including builders, engineers and subbies on a site install, are not harmed. General risk and workplace management sets that duty out plainly.
As a fabricator, that duty runs across everything the job touches: the steel, aluminium and stainless coming through shop drawings, cutting and folding, the welding itself, the powder coat and galvanising arrangements with your suppliers, and the balustrade, gate or structural steel once it leaves the workshop and goes up on site. It is not a once a year compliance task. It sits inside how every job runs, every week.
Where does the real risk sit in a fabrication workshop?
For most fabricators, the sharpest risks are the ones the trade has lived with for years and can become background noise: welding fume, machinery, and offcuts or sparks near the eyes. WorkSafe treats all three as serious, not minor.
On welding fume, WorkSafe is direct: “There is no known safe level of exposure to any type of welding fume,” and exposure, including mild steel welding fume, is linked to lung cancer and possibly kidney cancer in welders, see Health and safety in welding. A workshop that has run the same way for years can still be carrying that risk if extraction has not kept pace with the work.
Machinery, cutting gear and folding equipment carry their own duty: PCBUs must ensure, so far as is reasonably practicable, that plant is safe, with AS/NZS 4024 as the general benchmark WorkSafe refers to, see Safe use of machinery. Eye injuries caused by an object such as a metal fragment are specifically listed among the events WorkSafe treats as notifiable, see What events need to be notified?.
What do you have to do about welding fume and workshop air?
Beyond eliminating or minimising fume at the source, WorkSafe expects fabricators running welding routinely to arrange ventilation that works for the job in hand and to put regular health monitoring in place for welders who are routinely exposed.
Welding and local exhaust ventilation sets out that PCBUs must eliminate risks so far as is reasonably practicable and, where that is not possible, minimise them, and that PCBUs should arrange regular health monitoring for workers routinely exposed to welding fumes, including a baseline and then annual lung function test and a respiratory questionnaire. Measuring exposure against the relevant workplace exposure standards is a job for an occupational hygienist or other suitably trained person, not a guess at the end of the quarter, see the Workplace exposure standards document.
What happens if someone gets hurt, or you’re sharing a site with other trades?
If a notifiable event happens, the PCBU must make sure WorkSafe is told as soon as possible, and the site has to be preserved until WorkSafe says otherwise, see What events need to be notified?. You also carry a standing duty to have first aid equipment, trained first aiders and an emergency plan in place, in the workshop and on any site install, see PCBUs working together.
Most fabrication work does not happen in isolation. A balustrade, gate or structural steel job on site usually means your crew is working alongside a builder’s crew, other subbies and sometimes another fabricator’s installers. Where duties overlap like that, WorkSafe says each PCBU must, so far as is reasonably practicable, consult, cooperate and coordinate with the others, see Safe use of machinery and PCBUs working together. Working at height carries its own set of duties too, including training, supervision and ongoing monitoring of conditions, see Working at height in New Zealand.

What does keeping on top of this cost you in time, and where do AI agents fit in?
Health and safety record keeping (fume monitoring dates, first aid certificates, toolbox talks, notifiable event records) is easy to let slide when a job is running late, and that is exactly when a fabricator’s own data, who was on the tools, which jobs ran extraction, which site inductions are due, tells the truth better than memory does.
AI agents can take that record keeping off your plate. An AI agent is software that does a job the way you would, with your own wording and your own rules, so for a fabrication business that can mean tracking certification dates, flagging when a welder’s health monitoring is due, or chasing a missing induction before a crew goes on site. A second of these AI agents can sit over quoting so the fume extraction, PPE and training line items are never quietly dropped off a job to save time. Working from the business’s own data, data first, rather than what the owner remembers from last quarter, is what keeps this honest week to week instead of a scramble before an audit or after an incident. Greg coaches fabrication business owners online, starting from their own data, so whether the workshop sits in a city or a regional centre across New Zealand does not change how the coaching works.
Where can you check the current rules?
- Health and safety in welding: WorkSafe’s guidance on welding fume risk, ventilation and the health effects specific to welders.
- Welding and local exhaust ventilation: what PCBUs should do about extraction, ventilation and ongoing health monitoring for welding fume.
- Workplace exposure standards and biological exposure indices: duties around identifying, eliminating and minimising workplace health risks.
- Safe use of machinery: PCBU and worker duties around plant and machinery, and overlapping duties between PCBUs.
- Working at height in New Zealand: duties around training, supervision and monitoring for work done above ground.
- What events need to be notified?: what counts as a notifiable event and what a PCBU must do when one happens.
- PCBUs working together: advice when contracting: first aid, emergency plans and coordinating with other PCBUs on a shared site.
- General risk and workplace management: the PCBU primary duty of care and general risk management duties under HSWA.
How does Data First Coaching approach this?
Data First Coaching, built by Greg Allan, starts from the fabrication business’s own job and safety records through the Trade Business Intelligence, not a generic checklist, because gaps in a workshop’s health and safety are usually visible in its own data before they ever show up as an incident. Where fume monitoring dates sit, which jobs ran extraction and which didn’t, how often toolbox talks happen against how often the crew is on site: that pattern shows Greg where the real exposure sits for that business across New Zealand, not a textbook average. How to build the tracking and the agents that keep it honest is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member who is open minded, innovative and willing to share what they find.
