EV Charger Installers in Hamilton

Home EV charger installation in New Zealand typically costs $1,500 to $3,500 including the charger unit and wiring. A basic Level 2 (7kW) charger costs $800 to $1,500 for the unit, plus $700 to $2,000 for installation depending on the distance from your switchboard. A higher-powered 22kW three-phase charger costs $2,000 to $4,000 installed. Most homes need a dedicated circuit from the switchboard to the garage or carport.

Most EV chargers need a dedicated 32-amp circuit. If your switchboard is older or fully loaded, you may need a switchboard upgrade ($2,500 to $5,000) before installing the charger. Your electrician will assess your switchboard capacity and advise whether an upgrade is needed. Three-phase power is required for 22kW chargers — check with your electricity retailer about three-phase availability at your property.

The most common home charger in NZ is a 7.4kW single-phase unit, which charges most EVs from empty to full in 6 to 8 hours overnight. Popular brands in New Zealand include ABB, Schneider, Fronius, and Tesla Wall Connector. Look for a charger with Type 2 connectivity (the NZ standard), built-in RCD protection, load management capability, and weatherproofing if installing outdoors. Smart chargers can schedule charging for off-peak electricity rates.

All EV charger installations in New Zealand must be done by a registered electrician holding a current practising licence from the Electrical Workers Registration Board (EWRB). The installation must comply with AS/NZS 3000 wiring rules. A Certificate of Compliance must be issued after installation. Never use a standard wall socket for regular EV charging — it is not designed for the sustained high load and can overheat.
