AS/NZS 3000 home charger installs · EWRB-registered
Three install tiers — wall socket, dedicated 7kW, three-phase 22kW. Eight regions. Twelve EWRB-registered installers and a load-calc tool that tells you which tier your switchboard can actually take.
§01 The three tiers
Most NZ home EV charger installs are one of three things — wall socket, dedicated 7kW unit, or three-phase 22kW. Confusing them is the most common reason quotes feel impossible to compare.
Standard 3-pin or Caravan-style 16A outlet — slow charge.
Power
2.3–3.6 kW
Amps
10A / 16A
Range/h
10–18 km/h
Hardware + install · ex switchboard upgrade
The cheapest path. A dedicated outdoor-rated 10A or 16A socket on its own RCBO-protected circuit, no smart hardware. The car charges via its supplied portable cable. Fine for 30–80km daily commutes that have eight or more hours plugged in. Not for high-mileage households.
Run the calcSingle-phase 32A wall unit — the NZ default install.
Power
7.2 kW
Amps
32A
Range/h
35–45 km/h
Hardware + install · ex switchboard upgrade
The most-installed option in NZ. A dedicated wall-mounted unit pulling 32A on a single phase, on its own RCBO-protected circuit, with smart features (scheduled charging, Wi-Fi, OCPP). Adds 35–45 km of range per hour. Pairs well with rooftop solar via dynamic load management. The right call for most households.
Run the calcThree-phase 32A wall unit — closer to public-charger speed.
Power
22 kW
Amps
32A × 3 phases
Range/h
100–120 km/h
Hardware + install · ex switchboard upgrade
The fastest home option. Requires three-phase supply at the property — common in newer builds (post-2010), unusual in older single-phase homes. If single-phase, a supply upgrade through your network company adds $3,500–7,000 plus weeks of lead time. Adds 100–120 km/hour, but most cars can't actually accept 22kW AC; check your vehicle spec first.

Usually fine — RCBO line item only, $400–600.
§03 Why this exists
You can absolutely Google your way to an EV charger sparkie. Most people do. The problem isn’t finding electricians — it’s comparing them. Three quotes, three different scopes, three different definitions of “included”. Nothing lines up.
We do one thing — name the tier, then match you with installers who quote it the same way.
Wall socket (3kW), dedicated wall charger (7kW), three-phase (22kW). We name the three so you can compare quotes that are actually comparing the same install.
Every installer on the directory is registered with the Electrical Workers Registration Board, with proof of EV-charger-specific install hours. We confirm before listing.
NZD figures from real recent quotes — including the bits that actually move the price (cable run length, switchboard upgrades, RCBO costs).
Fill the form once, hear from up to three installers in your region. We don't take kickbacks; installers don't pay for placement.
