Yes, a gutter cleaner can legally work on a multi-storey commercial building in New Zealand — but there are significant health and safety obligations that must be met before anyone goes near the roof edge. The rules are stricter than for a standard residential job, and both the worker and the building owner share legal responsibilities under NZ law.
The Key Law: Health and Safety at Work Act 2015
All commercial work at height in New Zealand is governed by the Health and Safety at Work Act 2015 (HSWA) and its associated regulations. Under this framework, anyone doing work at height — including gutter cleaning — must manage the risk of a fall. On a multi-storey building, this is classified as a significant hazard, and a documented safe work plan is not optional; it is a legal requirement.
WorkSafe NZ is the regulator responsible for enforcing these rules. They publish detailed guidance on working at height, including the hierarchy of controls: eliminate the risk where possible, then minimise it using engineering controls (like scaffolding or an elevated work platform), and only use personal protective equipment (PPE) such as harnesses as a last resort or in combination with other controls.
What Does "Working at Height" Mean in Practice?
For gutter cleaning on a multi-storey commercial building, the practical requirements typically include:
- A written Safe Work Method Statement (SWMS) or equivalent risk assessment before work begins
- Fall protection systems — scaffolding, edge protection, or an elevated work platform (EWP/cherry picker) are preferred over harnesses alone
- Trained and competent workers — operators of EWPs, for example, need to hold a relevant unit standard or certificate of competency
- Appropriate PPE — helmets, non-slip footwear, harnesses where required
- Site-specific hazard identification — overhead power lines, fragile roofing materials, skylights, and weather conditions all need to be assessed
There is no single licence required specifically to clean gutters, but the equipment and methods used may require specific qualifications. For instance, operating a boom lift or scissor lift on a public site typically requires a certificate of competency under the Health and Safety at Work (General Risk and Workplace Management) Regulations 2016.
The Building Owner's Responsibilities
If you own or manage a commercial building, you are a Person Conducting a Business or Undertaking (PCBU) under the HSWA. This means you have a duty to ensure, so far as is reasonably practicable, that contractors working on your property are safe. You should:
- Ask for evidence of the contractor's health and safety plan
- Confirm they carry public liability insurance and, where relevant, employer's liability insurance (note: in New Zealand, workplace injury cover for employees is primarily provided through ACC, so confirm what additional employer liability cover is relevant with your insurer)
- Check that their workers are trained and competent for the specific task
- Ensure there is a clear process for managing emergencies
Simply hiring a contractor does not transfer all your legal responsibility. Both parties share overlapping duties under the HSWA.
Licensing and Restricted Work
Gutter cleaning itself is not a licensed or restricted trade in New Zealand — unlike electrical or plumbing work, there is no registration board for gutter cleaners. However, if the work involves:
- Electrical hazards (e.g., working near overhead lines) — a licensed electrician must assess or manage the risk; check EWRB for electrical worker requirements
- Roof repairs identified during cleaning — structural or weathertightness repairs may require a Licensed Building Practitioner (LBP); see LBP for details
- Building consent — routine maintenance like gutter cleaning does not require consent, but confirm any associated repair work with your local council
What to Look for When Hiring a Commercial Gutter Cleaner
When getting quotes for a multi-storey commercial building, ask prospective contractors:
| Question | Why It Matters |
|---|---|
| Do you have a SWMS for this job? | Legal requirement for high-risk work |
| What fall protection method will you use? | Scaffolding/EWP is preferred over harness-only |
| Are your staff trained for EWP operation? | Required for powered mobile plant |
| Do you carry public liability insurance? | Protects you if something goes wrong |
| Can you provide a health and safety plan? | Shows professionalism and legal compliance |
A reputable contractor will answer these questions confidently and without hesitation.
When to Call a Professional
For any gutter cleaning job above a single storey on a commercial building, you should always engage a professional contractor with demonstrated experience in working at height. The consequences of a fall from height are severe — it is one of the leading causes of workplace fatalities and serious injuries in New Zealand. Do not allow unlicensed or uninsured workers to attempt this work without proper controls in place.
