Electrician in Raglan — Cosine Electrical

Call Kris on 021 466 666

Cosine Electrical works across Raglan and out along the coast — Whaingaroa, Te Mata, Whale Bay, Manu Bay, and the lifestyle blocks on the way back to Hamilton. We're an electrical contractor with a skilled digger operator on the crew, which matters more in Raglan than most places: long underground runs to baches set back from the road are normal here, and they're easier when one team handles the dig and the electrical.

Raglan has its own electrical profile. Salt air shortens the life of switchboards and fittings. A lot of properties are baches owned by Auckland or Hamilton families, so the work needs to happen during a visit window. New builds keep going up. And the older Wainui Road and Bow Street places often have wiring that's well past its second decade.

Electrical services we provide in Raglan

• Underground services — trenched runs from house to sleepout, garage to bach, road to property — through to energising.

• Mains and switchboard upgrades — salt-affected switchboards, older bach boards, board lifts as part of a renovation.

• Residential renovation electrical — full reno fit-outs, bach upgrades, kitchen and bathroom work.

• Commercial repair and maintenance — Bow Street cafés, retail and hospitality.

• Illuminated signage — installs and repairs for the strip of businesses in town.

• Underground trenching — we trench our own runs.

• Periodic compliance testing — for commercial tenancies and short-term rental properties where compliance matters for insurance.

Why Raglan customers call Cosine

• Coastal-aware work. We spec switchboards and fittings knowing salt air is in the conversation.

• One quote for trench-to-board jobs. Long underground runs to bach properties are a common Raglan job.

• Booked visits that suit the owner. Many Raglan properties are owned by Auckland or Hamilton families. We work with absentee owners.

• Compliance for short-term rentals. Bach owners renting on Airbnb or Bookabach often need periodic compliance done for insurance.

Common Raglan jobs we handle

Bach switchboard upgrades are the regular run — older bach properties where the board is original to a 1970s or 80s build.

Underground services to sleepouts and second dwellings come up a lot, especially out toward Te Mata and Whale Bay.

For Raglan businesses we handle commercial repair and maintenance on the cluster of cafés, surf shops and retail along Bow Street and Wainui Road.

Service area

Raglan is a coastal run from our Waerenga base in the North Waikato — about 75 minutes via Hamilton. We also cover Hamilton, Ngāruawāhia and Te Awamutu on the way out.
