Yes, a scaffolder in New Zealand can — and in many cases must — refuse to erect a scaffold structure they believe poses an unacceptable safety risk. This isn't just a professional courtesy; it's backed by New Zealand law and is a cornerstone of responsible trade practice. Understanding why this happens, and what your options are as a homeowner, will help you keep your project moving safely.
The Legal Basis: Health and Safety at Work Act 2015
New Zealand's Health and Safety at Work Act 2015 (HSWA) gives every worker, including scaffolders, the right to cease or refuse work they believe is likely to cause serious harm to themselves or others. This is sometimes called the right to cease unsafe work. Under the HSWA, workers cannot be penalised or dismissed for exercising this right in good faith.
WorkSafe NZ is the regulator responsible for enforcing workplace health and safety law in New Zealand. WorkSafe takes scaffold safety seriously — falls from height are one of the leading causes of serious injury and death on NZ construction sites.
What Makes a Scaffold Structure "Unsafe to Build"?
A scaffolder might refuse a job for a range of legitimate safety reasons, including:
- Unstable or unsuitable ground — soft, uneven, or waterlogged ground that can't safely support scaffold base plates and standards
- Inadequate tie-in points — a building facade that doesn't offer safe anchor points to tie the scaffold to the structure
- Overhead hazards — proximity to live power lines (a strict exclusion zone applies under NZ regulations)
- Structural concerns — a building in poor condition that may not safely accept scaffold loads
- Access restrictions — site conditions that make erection itself dangerous without additional controls
- Design not fit for purpose — a requested scaffold configuration that doesn't meet the relevant New Zealand standard
Scaffolding in New Zealand is governed by the relevant NZS scaffolding standard (confirm the current edition with Standards NZ) and the broader requirements of the HSWA and its regulations. Scaffolders are trained to assess these risks before and during erection.
Professional Duty of Care
Beyond the legal right, scaffolders have a professional duty of care to everyone who will use or work near the scaffold — including your builders, painters, roofers, and any members of the public who pass by. Erecting a scaffold they know to be unsafe would expose them to serious legal liability and could cost lives.
Many scaffolding companies also carry out a formal site-specific risk assessment before starting work. If that assessment flags issues that can't be resolved, stopping the job is the responsible outcome.
What Happens Next? Your Options as a Homeowner
If a scaffolder refuses your job, don't panic — there are constructive steps you can take:
- Ask for a clear explanation — a professional scaffolder should be able to tell you exactly what the concern is.
- Address the hazard — for example, having an electrician arrange for power lines to be temporarily de-energised or shielded, or improving ground conditions.
- Get a scaffold design — for complex or non-standard structures, a scaffold design by a chartered structural or mechanical engineer may be required. This is common on larger or unusual projects.
- Seek a second opinion — another qualified scaffolding company may assess the site differently, or suggest an alternative approach.
- Check if a building consent is needed — some scaffold structures, particularly large or complex ones, may require a building consent. Always confirm with your local council, as requirements vary.
Scaffolding Is Restricted and Licensed Work
In New Zealand, scaffolding above certain heights is restricted work that must be carried out by a certificated scaffolder or under their direct supervision. Scaffolding certification sits under a separate industry framework; it is not part of the Licensed Building Practitioners scheme. Check with WorkSafe NZ for current certification requirements.
As a homeowner, you should never attempt to erect your own scaffold for work at height beyond the most basic low-level platforms. The risks of collapse, falls, and injury are severe.
When to Call a Professional
Always use a qualified, certificated scaffolding company for any work at height on your home. If a scaffolder raises safety concerns:
- Take them seriously — they are the expert on scaffold safety
- Work with them to resolve the issue rather than shopping around for someone who will cut corners
- Contact WorkSafe NZ if you believe a scaffolder is refusing work unreasonably or, conversely, if you witness unsafe scaffolding being erected
You can find qualified local scaffolders on tradedirectory.co.nz — always check that any scaffolder you hire holds the appropriate certification for the work involved.
