What bjc does

BJC Ltd (formerly BJ Cocksedge) is a privately held New Zealand industrial manufacturer operating since 1946 from a single facility at 9–15 Gregory Street, Naenae, Wellington. The company runs two main divisions. The Electric Heating division produces an extensive catalogue of custom and standard heating elements—including immersion heaters, band heaters, cartridge heaters, strip heaters, pocket heaters, drum heaters, duct heaters, finned air heaters, defrost/evaporator elements, commercial cooking elements, furnace/kiln elements, and load banks up to 500kW—manufactured using specialized equipment such as Kanthal spiral winders and rolling mills. The Wire Assembly division produces custom wiring harnesses, cable assemblies, battery cables, control panels, and adaptor cables for customers across automotive, agriculture, horticulture, medical, forestry, marine, and communications industries, using Komax automated wire processing and Cami Research 100% electrical/visual testing. The company also offers Contract Assembly services (complex product assembly such as automotive control boxes) and Turnkey Solutions (concept-to-production design, prototyping, and installation).

BJC earns revenue through a quote-based B2B custom manufacturing model, with pricing per enquiry and standard terms of 7 days from invoice or 20 days end-of-month for approved customers. Distribution is entirely direct—from the Wellington facility to customers in New Zealand and Australia (supported by a dedicated 1800 Australian sales line)—with no resellers or distributors. Certifications include ISO 9001 (since 1994), ISO 45001, and AS/NZS 4801, and the company is ROHS compliant. Offshore manufacturing partnerships supplement in-house capacity for specialized processes and small runs. Ownership is private, with a management buyout in 2008 having expanded the wiring division; the senior management team of nine, led by Managing Director Kean O'Neill, oversees operations. Revenue, headcount, and external ownership are not publicly disclosed.
