Electrical Inspections Auckland

When You Need One

When You Need an Electrical Inspection

Five situations come up over and over. If you’re in one of them, you probably need an inspection.

Buying a house. A pre-purchase electrical inspection is settlement protection. We check the switchboard, the wiring, the earthing, and the RCDs (safety switches) before you sign. A written report in your hand is leverage at the negotiating table. Worst case you walk. Best case you knock the price down by the cost of the remediation.

You’re a landlord. The Healthy Homes Standards don’t spell out “get an inspection every 3 years” in those words, but they require RCD protection, an adequate earth system, and compliant heating. If you own a portfolio, periodic inspections protect you when the next tenant calls Tenancy Services. Commercial buildings on a BWOF (Building Warrant of Fitness, the annual compliance certification for commercial buildings) cycle need the electrical side documented too.

Your insurer asked for one. Older properties, properties after a claim, or properties with a known electrical history sometimes get flagged at renewal. The insurer wants written evidence the installation is safe. We give them a report in the format they expect.

The switchboard’s older than you are. Ceramic fuses, no RCDs, a board half rewired in the 80s and never touched since. That’s not a switchboard, that’s a liability. An inspection tells you what’s still safe and what needs to go. From there we can quote a switchboard upgrade if it makes sense.

Something happened. Lightning strike, surge, partial flood, a small fire, a tree on the roof. Anything that could’ve stressed the wiring. Insurance might want the inspection, you might just want peace of mind. Either way, we run the tests and tell you what’s intact.

What We Handle

What We Handle: Three Inspection Services

We bundle three related services because most jobs need at least two of them. Here’s what each one covers.

A. Periodic Electrical Inspection

Periodic inspection is the full health check. We work to Section 8 of AS/NZS 3000 (NZ Wiring Rules), which sets out exactly what gets tested and what counts as a pass.

The visual side comes first. Switchboard condition, cable routing, accessory mounting, signs of overheating, anything that looks rough. A lot of faults are caught here before a tester is plugged in.

Then the electrical tests. Insulation resistance testing checks whether the cable insulation between live conductors and earth is still intact, which is the test that catches deteriorated rubber-insulated wiring in older Auckland homes. Earth bond (earth continuity) testing checks the property’s earthing system is connected end to end, because an earth path that’s broken somewhere doesn’t actually protect anyone. RCD trip-time testing confirms your safety switches still trip inside the milliseconds they’re meant to. Thermographic scanning under load picks up hot spots at terminations and inside the switchboard, the kind of stuff you can’t see from the outside.

What fails most often in Auckland? Old rubber-insulated wiring with degraded insulation, undersized earthing on properties before the modern MEN system was standardised, RCDs from the 1980s that are way past their service life, and switchboards with mixed-era components nobody documented.

B. Certificate of Compliance (CoC)

The Certificate of Compliance is a legal document. It’s a Licensed Electrical Worker’s formal declaration that prescribed electrical work meets the safety standards and the Building Code. Issued under the Electricity (Safety) Regulations 2010.

Prescribed work is the stuff the law actually cares about. Installing a new circuit. Replacing a switchboard. Installing hot water heating. Modifying permanent wiring. Anytime work falls into that bucket, a CoC has to be issued and kept on file. Many people confuse it with an Electrical Safety Certificate (ESC), which is a different thing. ESCs are issued after testing and inspection of an existing installation under the Building Act, usually triggered by a building consent. CoCs are issued after performing prescribed work.

What you get from us: a signed CoC with the work scope, the standards applied, the tests performed, and the results. Keep it. Insurers ask for it. Buyers’ lawyers ask for it. Building authorities ask for it. Records are retained on our side for the regulatory period, so if you lose your copy we can reissue.

C. Pre-Purchase Electrical Inspection

Pre-purchase is the one with the highest stakes for the shortest job. You’re about to spend hundreds of thousands of dollars. You want to know what’s hiding behind the switchboard cover.

We do a targeted scope: switchboard age and condition, earthing system (modern MEN or older), RCD presence and trip-time on every circuit that has one, visible wiring condition in roof spaces and under floors where accessible, smoke alarm compliance, hot water connection. Anything obvious that suggests unconsented work.

The deliverable is a written report your conveyancer, lender, or insurer can actually use. Plain English, photo evidence, prioritised. We rank findings as safety-critical, code-compliance, or future-replacement. You take it into the negotiation and you decide whether to push for a price adjustment, a vendor remedy, or to walk. We don’t tell you what to do with it. We just tell you what’s there.

Where We Work

Inspections Across Auckland

Auckland’s housing stock is a layer cake of eras, and each one fails in its own way. We’ve inspected enough properties across the city to know what to look for in each.

1950s state houses. Glen Innes, Avondale, Mt Wellington, Te Atatu. Standardised construction, often with original switchboards still in service. Deteriorated rubber-insulated wiring, ceramic fuses, no RCDs, undersized earthing. We see at least one of those four in nearly every inspection of a property this age.

1980s timber-frame subdivisions. West Auckland, the North Shore, Manukau. RCD technology was just becoming mandatory, so many homes have first-generation RCDs that are now well past their service life. The earthing is usually fine. The safety switches often aren’t.

2000s townhouses. Modern PVC cabling, RCBOs or split-load RCD switchboards. Generally tidy installations, but multi-unit developments sometimes have shared neutral or earth issues at the boundary between units that only show up under testing.

Ex-rental flats and converted dwellings. The wildcard. Original installations layered with cheap modifications, additions wired without consent, and switchboards that don’t match the original supply authority connection. These are the inspections that take the longest because we’re untangling 40 years of decisions.

Whichever band yours falls into, we’ll come to you. We’re based in West Auckland and we cover the whole region.

How It Works

What to Expect

Every inspection runs the same four steps. Same process whether it’s a pre-purchase or a periodic.

Why TAE

Why Auckland Property Owners Choose Us

Plenty of sparkies will plug in a tester and write you something. Here’s what makes the difference.

EWRB-registered and trained to AS/NZS 3000:2018. Every inspection we sign off is performed by an electrician on the EWRB (Electrical Workers Registration Board) public register at kete.mbie.govt.nz. Verifiable. Current. That register is the whole point of EWRB. We do ongoing electrical maintenance for property managers across the city, so we see what actually breaks in Auckland homes, not what the textbook says should.

Reports buyers and insurers can actually use. Photos. Plain English next to the technical detail. Ranked findings. No 18-page PDF where the important stuff is buried on page 11. If a lender or insurer needs a specific format, tell us up front and we’ll match it.

Lender and insurer-format ready. If your insurer asks for a Section 8 verification report with specific test results listed, we know what they want and we produce it that way. Same for lenders asking for buyer-due-diligence evidence.

Honest scope. We tell you what’s wrong. We don’t tell you what we’d like to sell you. If your switchboard’s fine, we’ll say it’s fine. If you need repairs rather than a full upgrade, we’ll quote repairs. The inspection report and the remediation quote are separate documents, and you decide which work happens.

Certificate of Compliance vs Electrical Safety Certificate, what’s the difference?

Different documents, different triggers. A Certificate of Compliance (CoC) is issued by the electrician after prescribed electrical work is completed, things like a new circuit, a switchboard replacement, hot water installation. An Electrical Safety Certificate (ESC) is issued after testing and inspection of an existing installation, usually triggered by a building consent under the Building Act. If we install a new switchboard for you, you get a CoC. If a building consent for an alteration requires verification of the wider installation, that’s an ESC. We issue both when the job calls for it.

When does the law actually require an electrical inspection?

Whenever prescribed electrical work is done, the Electricity (Safety) Regulations 2010 require a CoC, which involves testing as part of the certification. Outside of that, the law doesn’t mandate “get a periodic inspection every X years” for residential homes. But Healthy Homes obligations on landlords, BWOF cycles on commercial buildings, and insurance policy conditions on older properties all create practical reasons you need one. Honest answer: if you’re a landlord, an insurer’s chasing you, or you’re buying a house, get one.

What does a pre-purchase electrical inspection cover?

Switchboard age and condition, earthing system, RCDs on every circuit that has one, visible wiring in roof spaces and underfloor where we can get to it, smoke alarms, hot water connection, anything that looks like unconsented work. We test, we photograph, we write it up. The report’s ranked safety-critical, code-compliance, future-replacement, so you can take it to the negotiation and know which findings actually matter.

How often should a rental property be inspected?

Healthy Homes doesn’t set a calendar interval, but most property managers we work with do a periodic check every 3 to 5 years on residential rentals, and annually as part of the BWOF if it’s a commercial tenancy. After a tenancy change is also a good time, especially if the outgoing tenants ran heaters off extension leads for a couple of winters. Cheaper to catch it now than after an incident.

What fails most often in Auckland inspections?

Four things, in roughly this order. Rubber-insulated wiring from the 50s and 60s with degraded insulation. Original ceramic-fuse switchboards with no RCDs at all. First-generation RCDs from the 1980s that no longer trip within spec. And undersized earthing on properties wired before the modern MEN system was standardised. Pick almost any property built before 1990 and at least one of those is sitting there waiting to be found.
