When hiring a scaffolder in New Zealand, it pays to know what qualifications and certifications they should hold. Scaffolding is classified as high-risk work under NZ health and safety law, meaning there are specific licensing and competency requirements that legitimate scaffolders must meet. Knowing what to ask for protects you, your property, and the workers on site.
Why Scaffolding Certification Matters
Scaffolding failures can cause serious injury or death. WorkSafe NZ regulates scaffolding as part of its oversight of high-risk construction work. Under the Health and Safety at Work Act 2015 (HSWA) and the Health and Safety at Work (General Risk and Workplace Management) Regulations 2016, scaffolding above certain heights requires a licensed scaffolder to erect, alter, or dismantle it. This isn't just a formality — it's a legal requirement designed to keep everyone safe.
The High-Risk Work Licence (HRWL)
The most important credential to look for is a High-Risk Work Licence (HRWL) issued by WorkSafe NZ. Scaffolding is specifically listed as a class of high-risk work, and anyone erecting, altering, or dismantling suspended scaffolding or cantilevered scaffolding must hold the appropriate licence class.
The main scaffolding licence classes in NZ are:
| Licence Class | Scope |
|---|---|
| Scaffolding – Basic | Tube and coupler or modular scaffolding up to 5 metres |
| Scaffolding – Intermediate | Scaffolding up to 15 metres |
| Scaffolding – Advanced | All scaffolding types, including complex and suspended systems |
Always ask to see the scaffolder's current HRWL card. You can also verify licences directly through WorkSafe NZ.
Note: Basic scaffolding (such as a simple hop-up or platform under 5 metres) may not always require a licence, but the moment work becomes more complex or reaches greater heights, a licensed scaffolder is legally required.
New Zealand Trade Certificates and Unit Standards
Beyond the HRWL, professional scaffolders typically hold qualifications through the New Zealand Qualifications Authority (NZQA) framework. These are usually achieved through industry training organisations and cover the unit standards relevant to scaffolding work. Look for:
- National Certificate in Scaffolding (or equivalent NZQA-recognised qualification)
- Completion of relevant unit standards covering erection, inspection, and dismantling of scaffolding systems
These qualifications demonstrate that the scaffolder has been formally trained and assessed, not just self-taught.
Site Safety Cards and Induction
Most professional scaffolders working on commercial or larger residential sites will also hold a current SiteSafe passport or equivalent site safety card. While this isn't a scaffolding-specific licence, it shows the worker has completed general construction health and safety training — something reputable scaffolding companies require of all their staff.
Employer and Company Obligations
If you're hiring a scaffolding company rather than an individual, the company itself has obligations under the HSWA as a Person Conducting a Business or Undertaking (PCBU). A reputable scaffolding company should:
- Employ licensed scaffolders for all high-risk work
- Carry public liability insurance (ask for a certificate of currency)
- Provide a scaffolding handover certificate once the scaffold is erected — this document confirms the scaffold has been inspected and is safe to use
- Conduct regular scaffold inspections (at least every 30 days, or after any event that could affect its integrity, such as high winds)
What the NZ Building Code Says
Scaffolding itself isn't directly covered by a single NZ Building Code clause, but it is closely linked to construction site safety requirements. For residential building work, MBIE Building Performance sets out the rules around building consents and safe construction practices. If scaffolding is part of a consented building project, the licensed building practitioner (LBP) overseeing the work is responsible for ensuring all site safety requirements — including scaffolding — are met. You can check LBP details at Licensed Building Practitioners.
Red Flags to Watch Out For
Be cautious if a scaffolder:
- Cannot produce a current HRWL for the class of work being done
- Offers unusually low prices with no mention of insurance or certification
- Refuses to provide a scaffold handover certificate
- Has no company registration or verifiable business history
Cutting corners on scaffolding is never worth the risk. If something goes wrong and an unlicensed person erected the scaffold, you could face serious legal and insurance complications.
When to Call a Professional
For any scaffolding above 5 metres, or for suspended, cantilevered, or complex scaffolding systems, you must use a licensed scaffolder — this is a legal requirement under NZ law. Even for lower-level work, hiring a qualified professional is strongly recommended. Scaffolding failures are a leading cause of serious injury on NZ construction sites, and a properly certified scaffolder will ensure the structure is safe, compliant, and covered by appropriate insurance.
