Introduction
WorkSafe scaffolding requirements in New Zealand centre on one threshold; any scaffold where a person could fall five metres or more must be erected, altered or dismantled by someone holding the correct certification. This applies to a wider range of projects and people than many expect, from homeowners renovating a single house through to full commercial builds.
Homeowners planning a renovation, roof replacement or repaint need to know whether their job crosses into certified territory. Builders and contractors managing residential or commercial jobs need a quick compliance reference they can rely on. Property developers and project managers carry responsibility for site safety and WorkSafe notification, while tradespeople such as roofers and painters need to confirm the scaffold they are working from is compliant before they climb it.
Getting compliance right protects your budget, your timeline and, most importantly, everyone working on or near the site. Orange Scaffold has been building compliant scaffolding across Auckland for more than 20 years, and this guide draws on that experience to answer the questions we hear most often.

Whether you are comparing quotes for residential scaffolding or planning a larger commercial scaffolding project, the same rules will apply, and our team can talk you through either.
When Do You Need a Certified Scaffolder?
The core rule is straightforward. If a person could fall five metres or more from the scaffold, the work must be erected, altered or dismantled by, or under the direct supervision of, someone holding a Scaffolding Certificate of Competence (CoC) issued by SARNZ (Scaffolding, Access and Rigging Association of New Zealand). Every scaffolder on the Orange Scaffold team holds a current CoC, so jobs over five metres are handled correctly from the outset.
Below five metres, a CoC is not required, though the work must still be carried out by a competent person following good practice, with sound footings, correct bracing and proper edge protection. Scaffolds over 33 metres sit in a different category again and must be designed by a chartered professional engineer to reflect the added structural risk at that height.
You may notice some sources describe a grey zone between four and five metres. WorkSafe’s own guidance is clear that five metres is the deciding line, and that is the threshold Orange Scaffold works to on every job.
This is where a common homeowner question comes in: do you need scaffolding to replace a roof in NZ? If the highest point a person could fall from is five metres or more, the answer is yes, and the scaffold must be built by a certified scaffolder in line with these regulations, not erected informally by whoever happens to be on site that day. The same principle applies to working at heights more broadly, whether that is roofing, painting or installing guttering.
In summary, the three height thresholds are:
- Under 5 metres: no CoC required, but work must be done by a competent person following good practice.
- 5 metres or more: a certified scaffolder holding a CoC must erect, alter or dismantle the scaffold.
- Over 33 metres: the design must be verified by a chartered professional engineer.
Notifiable Work: When WorkSafe Must Be Told
Scaffolding from which a person could fall five metres, or more is classed as particularly hazardous work, which means WorkSafe must be given at least 24 hours’ notice before work begins. Responsibility for that notification sits with the PCBU carrying out the work, meaning the scaffolding company or building contractor, not the homeowner. Orange Scaffold takes care of this notification as a standard part of every eligible job, along with the paperwork that goes with it, so it is one less thing for you to manage.
Inspection Requirements and the ScaffTag System
WorkSafe requires scaffolding to be inspected throughout its working life, not only at the point it goes up, and the schedule follows a clear pattern:
Before the scaffold is used for the first time.
- At least every seven days while it remains in place.
- Again, after adverse weather or any alteration to the structure.
Every inspection must be carried out and recorded by a competent person, with the result displayed on site through the ScaffTag system. A green tag means the scaffold has been checked and is safe to use, while a red tag means access is not permitted until it has been reassessed. Orange Scaffold builds this inspection rhythm into every job, so your ScaffTag record stays current from day one.
Before stepping onto any scaffolding, it is worth checking the access point for a current, dated tag. If there is no tag, or the tag looks out of date, that is a clear sign to hold off and ask questions.
Structural and Safety Requirements
Beyond certification and inspection, WorkSafe sets out structural standards that every compliant scaffold must meet, largely drawn from the AS/NZS 1576 standard. Footings need to be sound and level, using sole boards where required, with bracing and ties back to the building and loads kept within rated limits.
Orange Scaffold builds every job using the German-engineered Layher scaffold system, chosen for its strength, reliability and speed of assembly, and every working platform gets full edge protection, which in practice means:
- Guardrails along the outer edge of the platform.
- Mid-rails positioned between the guardrail and the platform.
- Toeboards to stop tools and materials falling.
- Full planking, with boards secured against uplift from wind or movement, and no gaps for tools or materials to fall through.
Where scaffolding sits near a footpath or road, additional public protection measures such as debris netting or screening are required to keep passers-by safe. These standards are the baseline any PCBU must meet, and a competent scaffolding company should be able to walk you through each point without hesitation.
What to Ask Before You Hire a Scaffolding Company
Knowing the rules is one part of the equation. Turning that knowledge into a hiring decision is what protects your project, so before signing off on a scaffolding provider, it is worth working through the checklist below.
- Ask for proof of a current SARNZ Scaffolding Certificate of Competence for anyone erecting scaffold over five metres.
- Confirm the scaffold will be built to AS/NZS 1576, including footings, bracing, edge protection and planking.
- Check who is responsible for notifying WorkSafe of notifiable work and get this in writing.
- Ask how often the scaffold will be inspected, and how the ScaffTag system will be used on your site.
- Request evidence of public liability insurance, particularly if the scaffold will sit near a footpath or road.
- Ask for a clear handover process once the scaffold is ready for use.
Orange Scaffold meets every point on this checklist as standard, across everything from single-storey home renovations to large-scale commercial and multilevel developments, plus supplementary services like site fencing, mobile towers, roof edge protection and shrink wrap. Our experienced, friendly team is happy to walk you through exactly how, project by project.
Frequently Asked Questions
What height does scaffolding need a Certificate of Competence in NZ?
Five metres or more. Below that height, a certified scaffolder is not legally required, though the work must still be carried out by a competent person.
How often must scaffolding be inspected in NZ?
Before first use, at least every seven days while it remains in place, and again after adverse weather or any alteration.
Do I need to notify WorkSafe about scaffolding?
Yes, if the fall risk is five metres or more. WorkSafe must be notified at least 24 hours before work begins, and this responsibility sits with the PCBU, not the homeowner.
What does a red ScaffTag mean?
A red tag means the scaffold is not safe to use and access should not be attempted until it has been reassessed by a competent person.
