Getting multiple quotes for electrical work is smart — but knowing how to compare them properly is even smarter. In New Zealand, electrical work is tightly regulated for good reason: faulty wiring is a leading cause of house fires and electrocution. Asking the right questions upfront helps you choose a qualified, trustworthy electrician and avoid nasty surprises on the final invoice.
Is the Electrician Licensed and Registered?
This is the single most important question. In New Zealand, most electrical work is restricted work that must be carried out by a registered electrician. The Electrical Workers Registration Board (EWRB) maintains a public register — you can search it online to verify any electrician's licence before you commit.
Always ask:
- What is your EWRB registration number?
- Are you a Registered Electrician (RE) or a Licensed Electrical Inspector (LEI)?
- Will you issue a Certificate of Compliance (CoC) on completion?
A CoC is a legal requirement for restricted electrical work in NZ. If an electrician can't or won't provide one, walk away.
What Exactly Is Included in the Quote?
Not all quotes are apples-for-apples. One quote might look cheaper simply because it excludes materials, consent fees, or site clean-up. Ask each electrician to break down:
- Labour costs — hourly rate or fixed price?
- Materials — are cables, fittings, switchboard components, and light fittings included?
- Call-out or travel fees — especially relevant in rural areas
- Building consent fees — some electrical work (e.g. new switchboards, major rewires) may require a building consent from your local council
- GST — confirm whether the quoted price is GST-inclusive
A detailed, itemised quote makes comparison far easier and protects you if disputes arise later.
Is a Building Consent Required?
Some electrical work triggers the need for a building consent under the New Zealand Building Code, administered by MBIE Building Performance. Schedule 1 of the Building Act lists certain exemptions, but the rules can be complex. Always ask your electrician whether consent is needed, and confirm with your local council if you're unsure. Doing work without a required consent can cause problems when you sell your home.
What Is Your Experience With This Type of Work?
Electrical work varies enormously — from installing a single power point to rewiring an older villa or setting up a solar battery system. Ask:
- Have you done similar jobs before?
- Can you provide references or examples?
- Are you familiar with the specific requirements for older homes (pre-1980s wiring, aluminium wiring, etc.)?
Experience with your specific job type can save time, money, and headaches.
What Are Your Payment Terms?
Understand the payment structure before work begins:
| Question | Why It Matters |
|---|---|
| Is a deposit required? | Large upfront deposits can be a red flag |
| When is the final payment due? | Should be on or after completion |
| What payment methods are accepted? | Bank transfer, card, etc. |
| What happens if extra work is needed? | Get a variation process in writing |
Reputable tradespeople will be transparent about payment. Be cautious of anyone demanding full payment upfront.
What Warranty Do You Offer on Labour?
Materials often carry a manufacturer's warranty, but what about the workmanship itself? Ask:
- How long is your labour warranty?
- What is the process if something goes wrong after the job is done?
- Are you covered by public liability insurance?
A professional electrician should carry public liability insurance and be willing to stand behind their work.
How Will You Manage Health and Safety on Site?
Electrical work carries real risks — for the tradesperson and for your household. Under the Health and Safety at Work Act 2015, both the electrician and you as the homeowner may have responsibilities. Ask:
- Will the power be isolated safely before work begins?
- How will you protect children or pets on site?
- What PPE and safety procedures do you follow?
When to Call a Professional
All restricted electrical work in New Zealand must be carried out by a registered electrician. This includes installing or altering wiring, switchboards, power points, light fittings connected to fixed wiring, and any work on your main electrical supply. Homeowners may do very minor tasks — such as replacing a light bulb or a plug on a flexible cord — but anything involving fixed wiring is off-limits without registration. If in doubt, always call a licensed professional. You can find qualified local electricians on tradedirectory.co.nz.
Safety note: Never attempt restricted electrical work yourself. Unlicensed electrical work is illegal, can void your home insurance, and puts lives at risk.
