Emergency and exit lighting is classified as a specified system in New Zealand because, in a fire or power failure, it can be the difference between people finding their way out safely and becoming disoriented in the dark. If you own or manage a commercial, public, or multi-unit building, understanding your obligations around this system is essential — and getting it wrong can have serious legal and safety consequences.
What Is a Specified System?
Under the Building Act 2004, certain building systems that are critical to life safety or property protection are designated as specified systems. These systems must be listed on a building's compliance schedule, inspected and maintained to a set standard, and reported on annually. Emergency lighting and illuminated exit signs are among the most common specified systems you'll encounter in commercial and public buildings.
The compliance schedule is a document issued by your local council (territorial authority) that lists every specified system in your building, along with the inspection, maintenance, and reporting procedures required for each one. It's a legal document, and ignoring it carries real consequences.
Why Emergency Lighting Specifically?
The NZ Building Code — particularly Clause C (Protection from Fire) and related clauses covering means of escape — requires that people can safely evacuate a building in an emergency. When mains power fails (which often happens during fires or major incidents), normal lighting goes out. Emergency lighting automatically activates to illuminate escape routes, stairwells, and exits. Illuminated exit signs ensure occupants can identify the correct doors even in smoke-filled or unfamiliar environments.
Without functioning emergency lighting, escape routes become dangerous obstacles. That's why the system can't simply be installed and forgotten — it must be proven to work, reliably, every time it's needed.

The Building Warrant of Fitness (BWOF)
Most commercial and public buildings in New Zealand must display a Building Warrant of Fitness (BWOF). This is supplied annually by the building owner to the local council, confirming that all specified systems on the compliance schedule have been properly inspected, maintained, and are performing as required.
The BWOF is not something a building owner can self-certify. Each specified system — including emergency and exit lighting — must be signed off by a suitably qualified person. For emergency lighting, this is typically a registered Independent Qualified Person (IQP).
What Is an IQP and Why Do You Need One?
An Independent Qualified Person (IQP) is someone registered with your local council to inspect and report on specific specified systems. They are the only people authorised to complete the Form 12A inspection and maintenance certificates that underpin your BWOF.
For emergency and exit lighting, an IQP will typically be a licensed electrician with specialist fire systems knowledge, or a dedicated fire protection specialist. You cannot use just any electrician — they must be registered as an IQP with your council for this particular system type.

What Does Maintenance Actually Involve?
Maintenance of emergency and exit lighting generally involves a combination of routine checks and formal inspections. While the exact requirements are set out in your compliance schedule (and the relevant NZ Standard for emergency lighting systems — confirm the applicable standard with your IQP or Standards NZ), typical maintenance activities include:
- Regular functional tests — activating the system to confirm lights illuminate correctly when mains power is simulated as lost
- Battery duration tests — verifying that battery backup systems sustain lighting for the required period (commonly 90 minutes, but confirm with your IQP and compliance schedule)
- Visual inspections — checking for damaged fittings, failed lamps, or obstructed exit signs
- Logbook records — documenting all tests, faults found, and remedial work carried out
- Annual IQP sign-off — the formal inspection and Form 12A certification required for your BWOF
Faults found during testing must be repaired promptly. A system that fails its test cannot be signed off, which puts your BWOF — and your legal compliance — at risk.
Electrical Work Is Restricted
Any electrical work on emergency lighting systems — including replacing fittings, rewiring, or modifying the system — is restricted electrical work under NZ law. It must be carried out by a licensed electrician and a Certificate of Compliance must be issued on completion. You can verify an electrician's licence through the Electrical Workers Registration Board (EWRB).
Do not attempt to repair or modify emergency lighting wiring yourself. Aside from the legal risk, incorrectly maintained emergency lighting could fail at the worst possible moment.
Does This Apply to My Home?
The BWOF and specified system requirements generally apply to commercial, public, and multi-unit residential buildings — not standalone private homes. However, if you own a rental property, you still have obligations around smoke alarms under the Residential Tenancies Act. Check Tenancy Services for current requirements, and Fire and Emergency New Zealand (FENZ) for general household fire safety guidance.
When to Call a Professional
You should engage a registered IQP and/or licensed fire protection specialist if you:
- Own or manage a building with a compliance schedule listing emergency lighting
- Are unsure whether your building requires a BWOF
- Have emergency lighting fittings that are not functioning or have not been tested recently
- Are buying or leasing a commercial building and need to understand its compliance obligations
- Are undertaking building alterations that may affect the emergency lighting system
Always confirm your specific obligations with your local council and a qualified professional. Requirements can vary depending on your building's use, age, and compliance schedule.
