27 May What Are the Legal Requirements for Working at Heights in New Zealand?
Working at heights remains one of the highest-risk activities across New Zealand workplaces. Whether it’s routine HVAC maintenance, roof inspections, solar installation work, or commercial construction, the legal responsibilities around height safety are significant.
For building owners, facility managers, PCBUs, and contractors, understanding your obligations is not optional. Non-compliance can lead to serious injuries, WorkSafe investigations, financial penalties, and reputational damage.
In this guide, we’ll break down the key legal requirements for working at heights in New Zealand and what commercial building owners need to know to stay compliant.
What Counts as “Working at Heights”?
There is a common misconception that height safety rules only apply when working several metres off the ground.
In reality, New Zealand regulations focus on the risk of a fall causing injury, not simply the height itself.
That means even low-level roof work, access to plant equipment, or maintenance near skylights can require fall protection systems.
Examples include:
- Commercial roof maintenance
- HVAC servicing
- Gutter cleaning
- Solar panel installation
- Roof inspections
- Accessing elevated platforms
- Construction work
- Warehouse maintenance
If there is a risk of falling and sustaining injury, employers and PCBUs have a duty to manage that risk.
The Main Legislation Governing Height Safety in NZ
The primary legislation is the Health and Safety at Work Act 2015.
Under this legislation, PCBUs have a legal duty to ensure, so far as is reasonably practicable, the health and safety of workers and anyone affected by the work being carried out.
This includes:
- Providing safe access to work areas
- Identifying height-related hazards
- Implementing control measures
- Maintaining safety systems
- Ensuring workers are properly trained
- Regularly inspecting and certifying equipment
The Best Practice Guidelines for Working at Height in New Zealand also provide guidance around:
- Fall prevention systems
- Fall arrest systems
- Guardrails
- Roof access
- Anchor points
- Static line systems
- Ladder safety
Fall Prevention vs Fall Arrest
One of the most important legal principles in height safety is the hierarchy of controls.
Where possible, risks should be eliminated before relying on PPE.
This means:
- Eliminate the risk entirely
- Isolate workers from the hazard
- Minimise risk using protective systems
In practical terms, permanent guardrails and compliant roof walkways are generally preferred over relying solely on harness systems.
This is why many commercial buildings now install permanent height safety infrastructure.

Are Building Owners Responsible?
Yes.
Building owners and facility managers can still hold legal responsibilities even when contractors are performing the work.
If contractors are accessing unsafe roofs, non-compliant anchor systems, or unprotected skylights, the building owner may still be exposed to liability.
This is particularly important for:
- Commercial property owners
- Body corporates
- Schools and universities
- Industrial facilities
- Warehouses
- Retail centres
- Hospitals
Common Compliance Risks on Commercial Buildings
Some of the most common issues found during height safety inspections include:
- Missing edge protection
- Unprotected skylights
- Non-certified anchor points
- Inadequate roof access systems
- Damaged static lines
- Unsafe ladders
- Lack of inspection records
- Poor maintenance documentation
Many buildings were constructed before modern height safety standards became common practice.
As a result, older buildings often require upgrades to meet current safety expectations.
How Often Should Height Safety Systems Be Inspected?
Most height safety systems require annual inspections and recertification.
This can include:
- Anchor points
- Static lines
- Guardrails
- Walkways
- Ladder systems
- Access platforms
Regular inspections help ensure systems remain compliant, functional, and safe for ongoing use.
Why Permanent Height Safety Systems Are Becoming Standard
Commercial buildings increasingly require frequent rooftop access due to:
- HVAC servicing
- Solar maintenance
- Roofing inspections
- Communications equipment
- Drainage maintenance
Rather than relying on temporary systems every time access is needed, permanent systems provide:
- Improved safety
- Easier compliance
- Reduced liability
- Faster contractor access
- Long-term cost savings
Final Thoughts
Height safety compliance in New Zealand is not just about avoiding fines. It’s about protecting workers, reducing risk, and ensuring buildings remain safe for ongoing maintenance and access.
If your building requires regular rooftop access, now is the time to assess whether your current systems meet modern compliance standards.
A professional height safety assessment can identify gaps, reduce risk exposure, and help ensure your building remains compliant long-term.
