Emergency lighting is one of those building compliance requirements that tends to get overlooked until there’s a problem — an audit, an insurance query, or a system that fails when it matters.
For Auckland building owners and facility managers, here’s what you need to know.
What does the law require?
Under the New Zealand Building Act 2004, emergency lighting is a Specified System — meaning it has specific compliance obligations that don’t go away.
The requirements are set out in NZS 4238 (Emergency Lighting) and AS/NZS 2293 (the testing and maintenance standard). These specify minimum illumination levels, required duration (typically 90 minutes), placement, and testing intervals.
What is an IQP and why do you need one?
An IQP (Independent Qualified Person) is a person registered under the Building Act to inspect and certify Specified Systems. For most commercial buildings in Auckland, emergency lighting must be:
- Tested monthly — a brief functional test of each fitting
- Tested annually — a full 90-minute discharge test to confirm battery capacity
- Certified annually — an IQP must sign off and submit a Building Warrant of Fitness (BWoF) to Auckland Council
Building owners without a current BWoF are in breach of the Building Act. Northern Lights Lighting and Electrical holds IQP registration for emergency lighting — we carry out both testing and certification.
What types of emergency lighting are there?
Self-contained emergency luminaires — individual fittings with their own battery backup. Common in smaller commercial buildings and retail spaces.
Central battery systems — a single battery bank powering multiple fittings. More common in larger buildings.
Maintained vs non-maintained fittings — maintained fittings are on continuously. Non-maintained fittings only activate when mains power fails.
What happens if emergency lighting fails an inspection?
Fittings that fail the annual 90-minute test — typically due to battery degradation — must be replaced before the BWoF can be issued. Battery life in self-contained fittings is typically 3–5 years, so older buildings often require batch replacements.
We keep records of all fitting ages and test results, so you get early warning before failures.
Common questions
Do I need emergency lighting in my Auckland retail premises?
Almost certainly yes, if customers or staff are present. The specific requirement depends on floor area, occupancy, and layout.
How often does emergency lighting need to be tested?
Monthly functional tests, annual full-duration tests, and annual IQP certification for BWoF submission.
What does emergency lighting compliance cost?
Costs vary by building size and number of fittings. We provide fixed-price annual compliance packages for most commercial clients — contact us for a quote.
What if my building doesn’t have a BWoF?
The first step is an IQP assessment to understand your current compliance position. We can work with you to bring the building into compliance without unnecessary disruption.
