Porirua was planned from the late 1940s as a satellite city built around state housing. The first state house in the basin went up in 1949, more than 2,700 were built in Porirua East and Cannons Creek, and by 1977 78% of the city's housing was state owned. Tītahi Bay turned from a seaside resort into a state housing suburb after the war, Paremata grew once the 1936 bridge opened, and Whitby was planned in the 1960s, with its first sections sold in 1970.
That history leaves Porirua with a lot of homes built within a few decades of each other, many still on older switchboards with limited RCD protection. A switchboard upgrade is often the first step before adding a heat pump or an EV charger installation, and long-life or hard-wired smoke alarm installation is worth doing in rentals and family homes alike. We test, explain what we find and give you a written, fixed price.

Common Home Types in Porirua
State houses from 1949 onwards fill Porirua East, Cannons Creek and much of Tītahi Bay, including the Austrian state houses photographed at Tītahi Bay in 1951. Wiring from the late 1940s and 1950s may include rubber-insulated cable, and boards from that time seldom have the space or RCD protection needed for new circuits. Whitby is different: it was comprehensively planned, its first homes were occupied in 1971 and about 2,000 houses stood by 1998, so it is generally wired in plastic-sheathed cable, often with an original board that is now decades old. Development continues in the hills behind Whitby, and Papakōwhai's newer homes above Paremata usually have modern boards that make an EV charger simpler to add.
What Porirua Conditions Mean for Your Wiring
Porirua wraps around its harbour, so homes in Tītahi Bay, Paremata and along Whitby's inlet shore can fall inside the 500 metre sea spray zone that BRANZ applies to harbours as well as the open coast. Salt shortens the life of outdoor sockets, security lights and meter boxes, so we fit coastal-rated gear and check existing fittings when we visit. The city centre and Kenepuru sit beside the Porirua Stream, which the council manages with Greater Wellington for flood risk, and any electrics that have been under water need testing before use. Away from the water, Porirua East, Cannons Creek and Whitby are built on hills, so cable runs to garages and sheds often cross slopes and need planning. Wellington Electricity runs the lines network here.

Electrician Porirua FAQs
Do Porirua state houses need rewiring?
Some do. Houses from the late 1940s and 1950s may still have rubber-insulated cable, which becomes brittle with age. Others were rewired years ago. We inspect the wiring and the board and tell you whether a rewire, a partial rewire or just a new switchboard is needed.
What smoke alarms does a Porirua rental need?
Tenancy Services sets the rules nationally. A rental must have working smoke alarms within 3 metres of each bedroom door and on every level, and new or replacement alarms must be photoelectric with a long-life battery or hard-wired. We can fit, test and replace them.
Can you put an EV charger in a Whitby garage?
Usually. We check the board's space, capacity and earthing first. WorkSafe guidance requires a dedicated circuit with Type B RCD protection, or a Type A RCD with an RDC-DD. If the original board cannot take it, we quote the upgrade alongside the charger.
Why are my outdoor lights near the harbour corroding?
Salt spray. BRANZ treats land within 500 metres of the sea, harbours included, as the highest sea spray zone, and salt collects on sheltered fittings. Coastal-rated fittings and sealed connections last far longer than standard ones.
