HSWA 2015 + WorkSafe NZ scaffolding guidelines

Scaffolding regulations in New Zealand

Scaffolding is one of the highest-risk activities in NZ construction. Here are the legal requirements for erection, inspection, and certification.

📋 HSWA 2015, Section 36 + WorkSafe NZ scaffolding guidelines

When is an LBP (scaffolding) required?

Scaffolding over 5 metres requires a Licensed Building Practitioner with a scaffolding licence class to erect and dismantle it, plus a Record of Work. Under 5 metres: no LBP required by Building Act, but HSWA still requires a competent person.

Guardrail standards

  • Top rail: 900–1100mm above platform
  • Mid rail: approximately halfway
  • Toeboard: at least 150mm high
  • Planks: minimum 200mm wide, secured, gaps no more than 25mm

Pre-use inspection

Inspect before first use, after any alteration, after any event that could have affected stability, and at regular intervals (WorkSafe recommends at least weekly). Carried out by a competent person and documented. Defects: tag out of service until repaired.

Loading

Never overload — a leading cause of collapse. Design load must be displayed on the scaffolding. Engineer's design required for complex scaffolding.

Exclusion zones

Establish and enforce an exclusion zone beneath and around scaffolding. Toeboards and netting help contain falling tools and materials.

Tag system

Green tag = inspected and safe to use. Red tag = must not be used. Workers must check the tag before using scaffolding.

Frequently asked questions

Can workers erect their own scaffolding?
Under 5m: a competent person can. Over 5m: an LBP scaffolding licensee must be involved. All cases: HSWA requires safe work and pre-use inspection.
Do I need scaffolding for roof work?
Not necessarily — other fall protection may be more appropriate. Risk-assess the specific situation.
What if scaffolding is damaged?
Tag red and take out of service immediately. Inspect and repair before reuse. Investigate the cause.
Who is responsible if a subcontractor is injured on site scaffolding?
The principal contractor has primary responsibility. All PCBUs on site have overlapping duties.
