Before you hire
Auto electrical faults can be difficult to diagnose. Ask whether they charge a diagnostic fee, what equipment they use to read fault codes, whether they offer a mobile service if the vehicle will not start, and whether they have experience with your specific make and model, particularly for EVs or vehicles with advanced driver assistance systems.

Before you book an auto electrician on the North Shore
Drawn from 332 customer reviews collected for this page. The first answer is what it costs.
What do auto electricians typically charge in New Zealand? expand_more
Hourly rates for auto electricians in New Zealand run from $90 to $150 plus GST, with Auckland workshops sitting toward the upper end. A separate diagnostic fee of $80 to $150 plus GST is common, and this may or may not be credited against your repair bill if you proceed.
Common jobs like alternator replacement or starter motor work often run $300 to $600 all up, depending on parts and access. Under the Consumer Guarantees Act 1993, any repair must be completed with reasonable care and skill, giving you a legal basis to dispute poor work or surprise charges.
What should a proper auto electrical diagnosis include, and what does it cost? expand_more
A basic scan tool reading, which pulls fault codes from your vehicle's onboard computer, costs between $80 and $150 at most North Shore workshops, and a printed or explained report of those codes should come with it. Fault codes point toward a problem but do not confirm the exact cause, so a thorough diagnosis also involves circuit testing, component checks, and sometimes recreating the fault condition before any parts are ordered.
Some workshops credit the diagnostic fee against the repair cost if you proceed, but this varies, so confirm that arrangement before you authorise anything. One reviewer noted that a technician solved in two hours a problem the owner had been chasing for two days, which shows how much diagnostic skill matters beyond just plugging in a scanner.
Are all auto electricians qualified to work on EVs and hybrids? expand_more
Standard auto electrical training does not cover high-voltage hybrid and EV systems, and WorkSafe New Zealand guidelines make clear that anyone working on systems above 60V DC or 25V AC should hold recognised competency training, aligned with the New Zealand Qualifications Authority (NZQA) framework and delivered through providers such as Competenz, the Industry Training Organisation for the automotive sector. Before leaving an EV or hybrid, ask the technician directly whether they have completed unit standards covering high-voltage systems, and check that the workshop has insulated tools rated for that work, since qualification alone does not guarantee safe practice without the right equipment. One reviewer in these results did mention a positive hybrid battery service experience, but that is not evidence that every workshop on the Shore has the required high-voltage training.
What are the warning signs of an auto electrician you shouldn't trust? expand_more
- –Quoting exclusive of GST without disclosing that upfront, making the price appear cheaper than it is until the invoice arrives.
- –Charging a diagnostic or inspection fee and then returning the vehicle with the fault unresolved and no clear explanation of what was actually tested.
- –Fitting parts that do not match what was invoiced, such as speakers retailing far below the price charged, or charging for a seal that was never installed.
- –Failing to call before exceeding a quoted amount, leaving you with a bill you had no chance to approve.
- –Returning a vehicle with a new fault introduced during the repair, such as a loose battery terminal or a damaged lens, and then disputing responsibility.
- –Escalating to confrontation or refusing to engage reasonably when a customer raises a legitimate concern about the work done.
What should you ask before leaving your vehicle with an auto electrician? expand_more
- –Ask whether the diagnostic fee is credited against the repair cost if you approve the work, and get that confirmed in writing or by email.
- –Ask them to call you before proceeding if the cost is going to exceed a set amount, since some workshops will keep working and present a larger bill without prior approval.
- –Ask how long the diagnosis is expected to take, so you are not left without your vehicle for days when the fault could be scoped quickly.
- –Ask whether parts used will be genuine, OEM-compatible, or aftermarket, and confirm the parts cost is itemised separately on the invoice.
- –Ask what warranty applies to both the parts and the labour, as reputable operators will stand behind their work for a defined period.
- –If you own an EV or hybrid, ask specifically whether the technician holds recognised high-voltage training through a provider aligned with the New Zealand Qualifications Authority (NZQA) framework before authorising any work on the drivetrain or battery system.

How are the top auto electricians on the North Shore chosen? expand_more
We build this page from Google Maps results for auto electricians on the North Shore. Each one is scored on its public rating and review record. Businesses outside the area, or whose reviews describe a different line of work, are left out, and a business whose main Google category is a different trade is held back until a person has checked what it does. A business whose website no longer resolves and that has had no Google review for six months is treated as dormant and left off the page until either changes. Every category and city is rechecked on a rolling cycle, about every two to three months. A location with a subscribing business is rechecked every month, and the whole page updates with it. See how we rank for the full method.
