What's local about Cambridge's power
Usually Waipa Networks, sometimes WEL
Most of Cambridge is on Waipa Networks, whose 24-hour fault line is 0800 800 769. WEL Networks, the Hamilton lines company, says it also supplies some Cambridge subdivisions, so check the lines company named on your power bill before you ring.
A newer substation for a bigger town
Waipa Networks' Hautapu substation, linked to Transpower's grid at Hautapu, added capacity and resilience for Cambridge and more room for new homes and businesses to connect.
Growth on top of an old town
Cambridge had 21,366 people in 8,187 dwellings at the 2023 Census, up 32.6% in ten years, and 22.5% of residents were 65 or older. The town has many historic and heritage buildings, and its electric street lights first came on in 1922.
Storms still bite
Beyond the 2008 tornado, a severe storm in February 2026 left around 1,300 Waipa Networks customers without power at its peak, with almost all back on within 24 hours.
A quarter of households rent
At the 2023 Census, 25.99% of households across Waipā District didn't own their home or hold it in a family trust. That's the district figure, not Cambridge alone.
The jobs that come up most in Cambridge
Repairs after storm damage. When a roof lifts or a tree comes down, water can get into ceiling wiring and light fittings. An electrician tests the affected circuits before they go back into use and replaces what's damaged.
Add-ons for new homes. EV chargers, outdoor lighting and extra circuits for a garage or sleep-out. A home charger needs its own circuit and a Type B RCD, and the electrician should check your home's maximum demand first.
Upgrades in older homes near the centre. Switchboards with fuses and no RCDs, and wiring that's been extended over the decades. Rewires and new circuits are general work, so you get a CoC and an ESC.
If we owned a Cambridge home
After any storm that lifted roofing or let water in, we'd have the lighting circuits tested before trusting them again. In a newer house we'd plan an EV charger now, even if the car is a year off, so the cable runs while the walls are easy to get at.
