Your Onehunga Electrician Since 1952
BW Henderson Electrical has been serving Auckland homeowners and businesses since 1952. As a result, we are the Onehunga electrician that local residents and businesses have relied on for over 70 years. We provide residential, commercial, industrial, and solar electrical services for properties throughout Onehunga and the surrounding Central and South Auckland suburbs.
Onehunga is a suburb with genuine character — a mix of older residential homes, a busy commercial strip along High Street, and a light industrial area near the Onehunga Port and Penrose boundary. In addition, Onehunga has a high rental population, which means Healthy Homes electrical compliance is a common requirement for local landlords and property managers. Our EWRB-registered electricians are therefore experienced across the full range of residential, commercial, and industrial electrical work that Onehunga requires. Furthermore, every job is backed by a $20,000 Master Electricians workmanship guarantee. Installation quotes are free — however, a charge applies for fault-finding and repair assessments.

Why Choose BW Henderson as Your Onehunga Electrician?
Over 70 Years Serving Auckland
BW Henderson Electrical has been completing electrical work for Auckland homes and businesses since 1952. Consequently, we are one of the most established electrical contractors in the region — not a national franchise. Moreover, most of our Onehunga clients come to us through referrals from neighbours and existing customers. That is why quality and reliability matter to us on every job.
24/7 Emergency Response
Electrical faults don’t keep business hours. Therefore, we provide 24/7 emergency callout response for residential, commercial, and industrial clients throughout Onehunga and the wider Auckland area. Call us any time on 09 298 1944.
SiteWise 100 Certified
BW Henderson holds a SiteWise 100 certification — New Zealand’s highest contractor health and safety rating. As a result, we are approved to work on industrial sites and commercial facilities in and around Onehunga and the Penrose industrial area.
Master Electricians Quality Assured
As a member of Master Electricians New Zealand, all our work is backed by a $20,000 workmanship guarantee. In addition, all our electricians are registered with the Electrical Workers Registration Board (EWRB), so every job is legally compliant.
Thermal Imaging Technology
We use thermal imaging cameras to detect hidden electrical faults — such as overloaded circuits and failing connections — before they become dangerous. This is particularly useful for older Onehunga homes and commercial buildings where wiring may be well past its service life.
Part of French Group
BW Henderson is part of the French Group, a family-owned Auckland business with deep roots in the electrical industry. This means we have the resources to handle large commercial and industrial contracts, while still delivering the personal service of a local contractor.
Electrical Services for the Onehunga Community
About Onehunga
Onehunga is a well-established suburb on the southern edge of Auckland’s isthmus, situated between the Manukau Harbour and the Southern Motorway. The suburb has a strong community identity and a rich history — it is home to one of Auckland’s oldest town centres, with the High Street commercial strip and Onehunga Mall serving as the local retail hub. In addition, the waterfront Taumanu Reserve and the restored Onehunga Wharf area have become popular destinations for both locals and visitors, offering foreshore walks and harbour views across the Manukau.
Furthermore, Onehunga has a practical mix of older residential housing, a growing rental population, and a light industrial precinct that borders Penrose. As a result, we carry out a broad range of electrical work in the area — residential switchboard upgrades and rewiring for older homes, Healthy Homes compliance assessments for landlords with rental properties, commercial electrical fit-outs and maintenance for High Street businesses, and industrial electrical work for clients in the Penrose and Onehunga Port area. We service all of Onehunga and the surrounding suburbs including Penrose, Epsom, Royal Oak, Mt Roskill, Three Kings, and Otahuhu.
