One of New Zealand's highest-risk sectors — and what it takes to work safely
Construction is one of New Zealand's highest-risk sectors, with the highest injury rate of any industry. The big killers and harmers are falls from height, being hit by vehicles or plant, and long-term harm from dust and fumes. The same HSWA duties apply as anywhere — eliminate or minimise risks — but the pace and overlap of work on site make planning and coordination essential.
Sites change daily, multiple businesses work on top of each other, and the hazards are some of the most serious in any industry.
WorkSafe targets construction as a priority sector because it carries among the highest rates of both acute harm (falls, vehicle and plant incidents) and chronic harm (dust, noise, hazardous substances). The constant change on a site — new trades, new tasks, new conditions — means risks that were controlled yesterday can reappear today, which is why coordination between everyone on site matters as much as any single control.
A handful of hazards account for most of the serious harm.
| Hazard | What to manage |
|---|---|
| Falls from height | Edge protection, scaffolds and platforms before harnesses; remember there is no safe height. |
| Vehicles & plant | Separate people from machines, manage reversing, and control site traffic. |
| Dust & fumes | Silica, wood and other dusts cause long-term lung disease — control at the source with water or extraction. |
| Asbestos | Assume older buildings may contain it; identify and manage it before disturbing it. |
| Manual handling | Mechanical aids and good task design to prevent musculoskeletal injuries. |
| Hazardous substances | Adhesives, solvents, fuels and more — inventory, SDS and safe handling. |
On a construction site the difference between safe and unsafe is usually planning and communication, not heroics.
Have a site-specific safety plan for the site and task analyses for high-risk work, induct everyone before they start, and keep a live picture of who is on site. Where multiple businesses share the work, your duties overlap — you must consult, cooperate and coordinate so nothing falls through the gaps. Good documentation isn't box-ticking here; it's how a fast-moving site keeps everyone on the same page.

Construction has among the highest rates of both acute harm (falls, vehicles, plant) and chronic harm (dust, fumes, noise), and the highest injury rate of any sector. WorkSafe targets it as a priority because sites change constantly and multiple businesses often work alongside each other.
Falls from height, being struck by vehicles or plant, and long-term harm from dust and fumes such as silica. Asbestos in older buildings, manual handling and hazardous substances are also significant. Most serious harm comes from this handful of hazards.
There is no law requiring an SSSP by name, but principals and main contractors almost always require one before you start, and the outcomes it delivers are required under the HSWA. A site-specific safety plan plus task analyses for high-risk work is standard practice.
When more than one business shares work, their duties overlap and they must consult, cooperate and coordinate with each other so far as is reasonably practicable. No business can assume someone else has a risk covered — coordination is a shared legal duty.
Yes. Construction has the largest number of workers exposed to toxic dusts and fumes, and dusts like silica cause serious long-term lung disease. Control dust at the source with water suppression or extraction rather than relying on masks alone.
