What McMullen & Wing does

McMullen & Wing is a privately held New Zealand boat building company founded in 1970 and headquartered at 21 Gabador Place, Mount Wellington, Auckland, on the Tamaki River. The company designs, engineers, and fabricates custom vessels in steel, aluminium, and advanced composites, ranging from 11-metre pilot launches and dive support boats to 50-metre superyachts. Its portfolio spans commercial marine craft — aquaculture harvesters, passenger ferries, workboats, and oil spill response vessels — and recreational builds including superyachts, America's Cup-era racing yachts, and custom leisure craft. Owner David Porter leads the business with family in technical and production management (Jeff Porter, Ben Porter); operations are supported by four construction sheds, a 300-tonne concrete slipway, a 65-tonne travelift, deep-water berths for vessels up to 50m, CNC plasma cutter, 120-tonne hydraulic press brake, and CNC router.

Revenue is generated through two primary streams: bespoke vessel new builds secured via competitive tender (government and commercial operators) or direct engagement (superyacht clients), and recurring refit, service, and maintenance work for long-tenured commercial clients. Pricing is contract-specific and not publicly disclosed. Named enterprise and government customers include Auckland Transport, Auckland Council, Whakatōhea Mussels, Fullers, Sanford, NZ Police, Ports of Auckland, Southern Discoveries, and DiveCo. Strategic positioning has shifted toward commercial marine in metal and composite, with a deliberate pivot into electric and hybrid passenger ferries through a partnership with EV Maritime Ltd to decarbonise Auckland Transport's fleet.

Recent strategic activity includes launching the AT1 carbon-fibre electric ferry in June 2025, scheduling the AT2 unit for February 2026, adding a fourth construction shed in 2024, and exporting custom davits to the United States. The yard's historical track record includes award-winning superyachts (Big Fish, Ermis2, Mea Culpa), America's Cup programmes, and long-lifecycle commercial builds — Stella (1976) remains in commercial service more than 40 years on, and the Waitemata pilot launch (1990) served Ports of Auckland for 25 years. The company is privately owned with no external funding or public listing, and is actively recruiting aluminium boatbuilders into 2026 to scale capacity.
