Home EV Chargers in NZ: Cost, Installation and Which to Buy

Do You Need a Wall Charger?

Not necessarily. Almost every EV can charge from a normal socket with a portable cable, and for short daily driving that can be enough. The limit is speed. WorkSafe's EV charging guidelines cap a portable charger on a standard 10 amp plug at 8 amps, or 10 amps only where the plug senses the temperature of its pins. That is about 1.8 kW, which Standards NZ puts at roughly 11 km of range for every hour the car is plugged in.

A single-phase wall charger runs at up to 7.4 kW (32 amps): about 44 km of range an hour on the same figures, or around 10 hours from flat to full. EECA's rule of thumb is that a smart wall charger is at least three times faster than a three-pin plug.

There is a middle option. An electrician can fit a 15 amp socket or a 16 amp caravan socket, either of which lets a portable charger run at 12 amps. Since January 2026, WorkSafe's guidance also allows a 32 amp socket for a 32 amp portable charger, but only after a maximum-demand check of the house, and it recommends load management alongside it.

Whatever you use, plug it straight into the wall. WorkSafe lists extension leads, adaptors, multi-boxes and cable reels among the unsafe ways to charge an EV.

How Fast: 7, 11 or 22 kW

Source: Standards NZ, SNZ PAS 6011:2023, Table 1. Those speeds only happen if the car can take them. Every EV has an onboard charger that sets its own ceiling for AC charging: around 3.6 kW on older EVs and up to 11 kW on newer ones. A 22 kW charger connected to a car with an 11 kW onboard charger charges at 11 kW, so check your car's AC charging rate before paying for more than it can use.

The faster chargers also need three-phase power, and the standard home supply on most networks is single phase. Adding phases is a job for your lines company and is quoted individually. What each network asks before a charger goes in is under installing one, below.

What a Home Charger Costs

There are two costs: the charger, and fitting it. The chargers in the table below list from $849 to $2,454 before installation.

Hardware only, as listed on 1 October 2026. Prices move, so check before you buy. Retailer prices come from NZ shops we do not name. Several shops also sell their own-brand 7 kW chargers, from $549 to $949. “On EECA's list” means EECA's approved smart charger list as its files stood on 18 August 2026. Listing is voluntary, so a charger that is not on it has not failed anything.

Fitting it depends mostly on your switchboard and how far the charger is from it. Two makers publish installed prices for a standard job. Evnex's 7.4 kW chargers cost $1,835 to $2,385 fully installed, and Tesla puts a straightforward installation at $750 to $1,500 on top of its $850 Wall Connector. EECA's figures put the charger higher than today's list prices: $1,000 to $1,500 for the unit, plus $500 to $1,000 to install it. Every published figure we could source, side by side:

The sources agree on what moves the price: the distance from the switchboard to the charger, whether the switchboard has room and capacity, how the cable gets there (through a roof space, or trenched across a section), and whether you need load management or a bigger supply. Price guides published by NZ electricians put a switchboard upgrade alone at about $800 to $4,000.

Ask for a fixed price after the electrician has seen your switchboard and where the car parks. A photo of the switchboard with its door open, and one of where the charger would go, helps them price it.

Smart Chargers and EECA's List

A smart charger connects to the internet, so it can be scheduled, controlled from an app, and told by a power company or network when to slow down. In EECA's 2025 research, 53% of people with a wall charger said theirs was smart.

EECA keeps a voluntary list of approved smart chargers. To qualify, a charger must run the open charging protocol OCPP (version 1.6 or later), keep charging if its connection drops, show the owner how much energy it uses, and by default wait a random delay of up to 10 minutes before it starts. Being on the list is voluntary and the maker has to apply, so a charger that is not on it has not failed a test. Tesla's and Evnex's home chargers are not on it.

Smart chargers are about to become a requirement. On 5 May 2026 the government decided that new EV chargers above 2.4 kW sold in New Zealand will have to meet minimum smart functions and carry a label, and EECA consulted on the technical rules until 4 September 2026. It is not law yet: it needs a change to the Energy Efficiency and Conservation Act, and no start date has been set. The rule is about the chargers that are sold, not about you, and MBIE says it would not force anyone to install a smart charger.

The government's reason is peak demand. It says unmanaged charging could increase a household's peak demand by up to 40%, and that smart charging could save households up to $220 a year by 2050.

Choosing a Charger

There is no single best charger, only one that fits your car, your house and whether you have solar. Work through it in this order:

• Your car's onboard charger. If the car takes 7 kW, a 22 kW charger buys you nothing today.
• Your supply. A single-phase home suits a 7.4 kW charger. Three phase opens up 11 and 22 kW, if the car can use them.
• Solar. If you have panels or plan to, choose a charger that can follow your surplus. Most need a CT clamp or a meter to see what the house is exporting, and some only do it with the same maker's battery.
• Your switchboard. If it is near its limit, choose a charger with overload protection, which slows charging while the house is busy.
• Fixed cable or socket. A fixed cable is simpler day to day. A socket means using your own cable, which lets one charger suit cars with different plugs.
• Warranty and support. The chargers in our table carry 3 to 4 year warranties where the maker publishes one. Ask who handles a fault in New Zealand.
• The Supplier Declaration of Conformity. EV chargers are a declared medium-risk product, so they can't be sold here without one. Ask the seller for it: they have to give it to you within 10 days.

Installing One

Fitting a wall charger is prescribed electrical work, so it must be done by an electrician who is registered and holds a current practising licence. You can check a licence with the Electrical Workers Registration Board. WorkSafe's advice to homeowners is plain: a wall-mounted charger must be installed by a registered electrician.

WorkSafe's guidelines ask for the charger on its own circuit from the switchboard, wired in rather than plugged in, with a lockable isolating switch. Outdoors it needs a weatherproof rating of at least IPX4, and in a garage it should be kept out of any area where petrol vapour can collect. Standards NZ suggests mounting it near where the car's charging port ends up, with its controls between 0.75 and 1.2 metres off the ground.

The circuit also needs protection that can detect the kind of fault an EV charger can produce. Since WorkSafe's January 2026 addendum, that means one of three things: a Type B RCD on the circuit, a Type A RCD paired with a DC fault detector (an RDC-DD), or a charger with a Type B RCD built in. The common Type A RCD on its own is not enough.

The electrician should check that your incoming supply can carry the extra load. The Electrical Workers Registration Board tells installers to check this especially above 15 amps, and to upgrade the mains or use smart charging control where the supply falls short.

When the work is finished you should receive a Certificate of Compliance within 20 days, and an Electrical Safety Certificate once the charger is connected. Keep both, because insurers and buyers can ask for them. An inspection by a second electrician is only needed for high-risk work, such as work on the mains.

Can you do it yourself? Not the charger. The law's homeowner exemption lets an owner-occupier do limited wiring that a licensed person then tests, certifies and connects, but WorkSafe says a wall charger must be installed by a registered electrician, and tenants and landlords can't do electrical work themselves at all.

On consents: no building consent rule names home EV chargers, and the Electrical Safety Certificate is what records that the electrical work meets the Building Code. If the job includes building work, such as a new carport, ask your council. Under planning rules, a private charger has been a permitted activity since 7 May 2026, so it needs no resource consent. One more date: from 13 November 2026, new chargers must meet the EV charging standards now written into the Electricity (Safety) Regulations. Chargers already installed are not affected.

What It Costs to Run

Charging at home is the cheapest way to run an EV. On EECA's figures, which include road user charges, it costs about $11 per 100 km charging at home off-peak, $14 at home on a standard rate, and $19 at a public fast charger.

Road user charges are part of that: $76 per 1,000 km for a battery EV and $38 for a plug-in petrol hybrid, which EVs have paid since 1 April 2024 (NZTA).

The saving comes from charging overnight. The Electricity Authority now requires the four large retailers to offer time-of-use plans, and it says about 70% of EV owners already charge overnight. Ask your retailer when its cheaper rate starts, set the charger or the car to begin after it, and compare plans on Powerswitch.

Charging From Your Own Solar

If you have solar panels, a charger that follows your surplus can fill the car with power you would otherwise export. On a single-phase home it needs about 1.4 kW of spare solar before it starts, because a car won't charge below 6 amps. Chargers that switch between one and three phases can start from about 1.38 kW.

How much solar that takes, and what it saves per kilometre, is in our guide to charging an EV from your own solar panels.

Renters, Apartments and Body Corporates

If you rent, a wall charger is a fixture, so you need your landlord's written consent, and Tenancy Services says a landlord can't unreasonably withhold it. Agree before the work starts who owns the charger when you leave: a fixture left behind becomes the landlord's unless you have agreed otherwise.

In a unit-title building, the body corporate can meter a car park and charge the owner for the EV's power, at the price the body corporate pays, under the Unit Titles Act. Buildings on one shared connection come under Standards NZ's commercial guidance, SNZ PAS 6010.

Powering the House From the Car

Two-way charging, where the car sends power back to the house (V2H) or the grid (V2G), is in trials in New Zealand, not yet in ordinary homes. Any two-way charger has to meet the same standard as a solar inverter, AS/NZS 4777, and lines companies treat it as generation that needs their approval first.

EECA says only two chargers available here meet New Zealand's requirements, both DC units, and one works only with the same maker's home battery system. Most car makers support two-way charging here only in approved trials, and EECA is running one in Queenstown with 30 to 40 chargers during 2026. If a charger is sold to you as V2H-ready, ask for the car maker's approval in writing.

Is There a Subsidy?

No. There is no government subsidy for home chargers in 2026. EECA's funding page for homes lists only Warmer Kiwi Homes, and the Energy Minister has said EV uptake is growing “without unnecessary subsidies from taxpayers”. We found no council, lines company or retailer rebate either.

What does exist is cheaper borrowing. ANZ, ASB, BNZ and Westpac green loans all list EV chargers as eligible; Kiwibank's sustainable energy loan does not. Rates and terms are in our green loan guide. Some chargers also come with the car: in EECA's research, 20% of dedicated home chargers came free with the vehicle.
