Your St Marys Bay Electrician Since 1952
BW Henderson Electrical has been serving Auckland homeowners and businesses since 1952. As a result, we are the St Marys Bay electrician that local residents and property owners have relied on for over 70 years. We provide residential and commercial electrical services throughout Saint Marys Bay and the surrounding Central Auckland suburbs of Ponsonby, Herne Bay, Freemans Bay, and the CBD fringe.
Saint Marys Bay is one of Auckland’s most prestigious inner suburbs — a compact hillside enclave of Victorian and Edwardian villas, bungalows, and character homes, many with stunning harbour views over Westhaven Marina and the Waitemata. Consequently, the suburb generates consistent demand for renovation electrical work, heritage rewiring, and high-specification residential installations. Our EWRB-registered electricians are experienced with older wiring systems, and 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.

Electrical Services for Saint Marys Bay Homes
About Saint Marys Bay
Saint Marys Bay is one of Auckland’s smallest and most prestigious suburbs, situated on a north-facing hillside between Ponsonby and Westhaven Marina, overlooking the Waitemata Harbour. The suburb is almost entirely residential — a quiet enclave of Victorian and Edwardian villas, character bungalows, and a small number of contemporary homes, many commanding exceptional views over the marina and inner harbour. As a result, Saint Marys Bay consistently ranks among Auckland’s most expensive real estate, and substantial investment in home renovation and restoration is common throughout the area.
Furthermore, the suburb’s heritage housing stock means that many Saint Marys Bay homes carry original or outdated wiring systems that are no longer adequate for modern electrical loads. Consequently, rewiring, switchboard upgrades, and renovation electrical work are among the most frequent jobs we carry out in the area. In addition, the suburb’s high-income demographic generates demand for premium residential electrical work — including home automation, EV charging, high-specification lighting, and solar installation. BW Henderson also services the adjacent suburbs of Herne Bay, Ponsonby, Freemans Bay, and the CBD fringe.
