The Electrical Workers Registration Board (EWRB) is the government body responsible for registering and licensing electrical workers in New Zealand. Its core job is to make sure that anyone carrying out electrical work has the right qualifications, skills, and character to do so safely — protecting both workers and the public from the very real dangers of faulty electrical installations.
What Is the EWRB?
Established under the Electricity Act 1992, the EWRB is an independent statutory body that sits within the broader regulatory framework overseen by WorkSafe NZ. It maintains a public register of all licensed and registered electrical workers in New Zealand, sets the standards for entry into the profession, and handles complaints and disciplinary matters when things go wrong.
Think of the EWRB as the gatekeeper for the electrical trade — much like the Plumbers Gasfitters & Drainlayers Board does for plumbing and gas work.
Registration vs Licensing — What's the Difference?
The EWRB uses two related but distinct terms:
- Registration — Recognises that a person has the required technical knowledge and qualifications in a particular class of electrical work (e.g. electrician, electrical inspector, or line mechanic).
- Licensing — Allows a registered person to actually carry out or certify electrical work. You must hold a current licence to legally perform electrical work in NZ.
There are several licence classes, including:
| Licence Class | What It Covers |
|---|---|
| Craftsman Electrician | Full range of electrical installation work |
| Registered Electrician | Most installation work under supervision |
| Electrical Inspector | Inspecting and certifying electrical work |
| Electrical Service Technician | Appliance and equipment servicing |
| Trainee | Working under supervision while studying |
Always ask your electrician which class they hold — it matters for the type of work they can legally do.
Why Does This Matter for Homeowners?
In New Zealand, electrical installation work is restricted work under the Electricity (Safety) Regulations 2010. This means it must be carried out by a licensed electrical worker. Unlicensed electrical work is not only illegal — it can void your home insurance, create serious fire and electrocution hazards, and cause problems when you sell your property.
The EWRB's public register means you can verify your electrician's credentials before they start work. Simply search their name or licence number on the EWRB website to confirm they are currently licensed.
What Work Can a Homeowner Do Themselves?
This is a common question, and the answer is quite limited. As a homeowner, you may generally:
- Replace a light bulb or fuse
- Replace a socket outlet or light switch like-for-like in some circumstances (check current regulations, as rules can change)
- Connect a plug to a cord on a portable appliance
However, any new wiring, consumer unit work, switchboard alterations, or installation of fixed appliances must be done by a licensed electrician. When in doubt, don't risk it — contact a professional.
Safety note: Electricity can kill. Even seemingly simple jobs can involve live conductors or hidden hazards. If you're unsure whether a task is restricted work, assume it is and call a licensed electrician.
How the EWRB Protects You
Beyond registration and licensing, the EWRB:
- Investigates complaints about electrical workers who may have performed substandard or unsafe work
- Takes disciplinary action, which can include fines, suspension, or cancellation of a licence
- Sets competency standards in partnership with industry training organisations
- Promotes ongoing professional development to keep electricians up to date with changing standards and technology
If you have a genuine concern about work carried out by a licensed electrician, you can lodge a complaint directly with the EWRB.
Building Consent and Electrical Work
Some electrical work requires a building consent from your local council, in addition to being carried out by a licensed electrician. For example, installing a new switchboard or significant rewiring in an older home may trigger consent requirements. Your electrician should advise you, but it's always worth checking with your local council. The MBIE Building Performance website has useful guidance on what work requires consent and what falls under Schedule 1 exemptions.
When to Call a Professional
You should always engage a licensed electrician for:
- Any new wiring or circuits
- Switchboard or consumer unit upgrades
- Installing heat pumps, EV chargers, or fixed appliances
- Outdoor or underground wiring
- Any work in a bathroom or wet area
- Fault-finding and repairs to existing wiring
A qualified local electrician can be found easily on tradedirectory.co.nz. Always ask to see their EWRB licence before work begins, and request a Certificate of Compliance (CoC) once the job is finished — this is your legal proof that the work was done correctly.
