How to Choose the Right Electrician

Electrical work is not the place to cut corners. A dodgy sparkie can leave your home with hidden faults that show up months later as a melted fitting or worse. Here’s a practical guide to choosing an electrician you can trust in NZ.

Confirm they’re registered and licensed

In New Zealand, almost all electrical work must be done by an electrician registered with the Electrical Workers Registration Board (EWRB). There are a few very narrow exceptions for homeowner work, but most of what you’d pay someone for is off-limits to unregistered people.

You can check any electrician’s registration for free on the EWRB public register. Search by name or business, and you’ll see their practising licence status, their classes of work, and whether they’ve had any disciplinary action. A legit electrician will have their EWRB number on their van, invoices and website.

What registration actually covers

• They’ve completed proper electrical trade training
• They pass mandatory ongoing competence checks
• They’re bound by the Electricity (Safety) Regulations 2010
• Their work is backed by a legally required Certificate of Compliance

Ask about their specific experience

Electrical work varies hugely. An electrician who fits out new builds for developers might be great at that, but less experienced at diagnosing a mystery fault in a 1950s villa. Same goes for solar installations, EV chargers, commercial work or marine electrics – these are specialisations.

When you describe your job, ask how often they do that type of work. A straight answer like “we do three to five of those a week” is a green light. Vague answers or hedging is a sign to keep ringing around.

Get it in writing, properly

Unless it’s a simple job under half an hour, insist on a written quote. A good electrician will be happy to provide one. Quotes should cover:

• Scope of work with clear descriptions
• Labour costs and hourly rate
• Material costs, itemised where possible
• Any call-out or travel fees
• Whether a Certificate of Compliance (CoC) is included
• Timeframe and payment terms

A CoC is mandatory for most prescribed electrical work. If an electrician won’t issue one, that’s a serious problem and you should walk away.

Look at reviews and reputation

Online reviews are useful, but don’t stop there. Good electricians usually come highly recommended by neighbours, family and trusted tradespeople like builders and plumbers. Local community Facebook groups can surface strong candidates quickly.

When reading reviews, focus on the comments about communication, tidiness and follow-through. Technical quality is assumed with a licensed sparkie. What you’re really buying is reliability and a proper job.

Red flags in reviews

• Repeated complaints about quotes changing after the job starts
• Callbacks needed for recurring faults
• Mess left behind, damaged plasterboard, no clean-up
• Missing paperwork, especially CoCs
• Aggressive responses to polite critical reviews

Ask about warranty and workmanship

Reputable NZ electricians typically offer at least a 12-month workmanship warranty on top of any manufacturer warranties for fittings, appliances or switchboards. Some extend to two years or longer on larger jobs.

Get it in writing, alongside the CoC. If something fails within the warranty period, you want clear proof of what was agreed.

Check insurance and safety standards

A professional electrician should carry public liability insurance of at least $1 million. Ask to see proof. If work causes a fire or damages your property and the electrician isn’t insured, you’re the one left holding the bill.

Also ask about their approach to safety. Do they use test equipment before and after work? Do they isolate circuits properly and tag out during the job? These habits are the difference between a safe tradesperson and a cowboy.

Get multiple quotes, but don’t just pick the lowest

Three quotes is usually enough to see the market price for your job. If one quote comes in well below the others, ask yourself why. Budget electrical work is rarely a bargain. Shortcuts on materials, rushing the job, or skipping the CoC can all make a quote look attractive until something goes wrong.

Mid-range quotes from reputable, well-reviewed electricians are almost always the best value. You pay a fair price and get proper documentation, warranty and peace of mind.

Emergency vs scheduled work

For routine work like new lighting, power points or switchboard upgrades, take your time and get it right. For emergencies (no power, burning smells, sparking outlets), call an electrician who runs a genuine after-hours service. Describe the problem clearly, and if they say it’s urgent, switch off the main at the meter board while you wait.

Final tip: communication matters

The best electricians keep you informed. They turn up when they say they will, explain what they’re doing in plain English, and let you know before any extra work is done. A bit of respect goes a long way in a trade where hiding work behind walls makes trust essential.
