Charger spec sheet

Three tiers,
in detail.

The three install tiers we cover, fully expanded — power, amps, cable spec, typical hardware, what each suits, and when to skip.

Tier 01

Wall socket

Standard 3-pin or Caravan-style 16A outlet — slow charge.

Total range

$650

to $1.6k

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.

Power

2.3–3.6 kW

Amps

10A / 16A

Phase

Single

Range/h

10–18 km/h

Cable

2.5mm² TPS, ≤25m run

On-site

Half-day install

Good for

  • Low-mileage households (<60 km/day)
  • Plug-in hybrids
  • Backup or holiday-home use
  • Renters who'll move in 12–24 months

Not for

  • High-mileage daily drivers
  • Two-EV households
  • Anyone who wants smart-charging or solar integration

Hardware examples

  • Dedicated weatherproof 16A outlet
  • Vehicle-supplied portable EVSE

Tier 02

Dedicated 7kW wall charger

Single-phase 32A wall unit — the NZ default install.

Total range

$2.3k

to $4.6k

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.

Power

7.2 kW

Amps

32A

Phase

Single

Range/h

35–45 km/h

Cable

6mm² TPS, ≤30m run

On-site

1 day install (excl. switchboard work)

Good for

  • Most NZ households
  • Daily commuters
  • Solar PV homes (with load-management features)
  • Households planning a second EV in 2–3 years

Not for

  • Very small consumer mains (under 60A) without switchboard upgrade
  • Households needing under-2-hour fast charging

Hardware examples

  • Tesla Wall Connector
  • Wallbox Pulsar Plus
  • EO Mini Pro 3
  • Zappi 7kW (solar-aware)
  • Schneider EVlink Home

Tier 03

Three-phase 22kW

Three-phase 32A wall unit — closer to public-charger speed.

Total range

$4k

to $8k

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.

Power

22 kW

Amps

32A × 3 phases

Phase

Three

Range/h

100–120 km/h

Cable

5-core 6mm², ≤40m run

On-site

1–2 days install (excl. supply upgrade)

Good for

  • Newer-build homes already on three-phase
  • Multi-EV households needing fast turnaround
  • Vehicles with 11–22kW AC capability (e.g. Renault Zoe, some Audi e-trons)
  • Homes adding solar + battery + EV in one project

Not for

  • Older single-phase homes (cost-prohibitive supply upgrade)
  • Vehicles capped at 7kW AC (most Teslas, most Leafs)

Hardware examples

  • Wallbox Pulsar Plus 22kW
  • Schneider EVlink Wallbox 22kW
  • ABB Terra AC 22kW
  • Charge Star Pro (NZ-built)

Common switchboard line items

The bit that often
surprises homeowners.

  • Modernise consumer mains (60A → 100A)

    Required for most older houses before 7kW becomes safe.

    $1.2k–$2.4k

  • Add RCBOs to a fuseboard

    Pre-1990 homes often need this regardless of EV.

    $600–$1.2k

  • Single-phase → three-phase supply upgrade

    Network company quote required; weeks of lead time.

    $3.5k–$7k
