What Connell Contractors does
Connell Contractors Ltd is a specialist New Zealand civil and energy infrastructure construction contractor headquartered in Hamilton, North Island. Founded in 1985 by Dave and Margo Connell as a two-person excavating operation, the company has grown into an 80+ staff enterprise with four regional offices (Hamilton, Auckland, New Plymouth, Taupo) and a 30+ project annual delivery cadence.
The company's services span three integrated verticals: pipelines (pump stations, water reticulation, dewatering, stormwater, sewerage, pipe bursting, marine works, and trenchless rehabilitation), energy infrastructure (switchyards, substations, transmission and distribution civil works including STATCOM and Faraday cage construction), and renewable energy civil construction (wind farms, solar farms, battery energy storage systems, and hydro). Technically demanding work in live electrical environments, brownfield sites, and constrained urban footprints is a deliberate focus, supported by an in-house steel fabrication division in Taranaki, horizontal directional drilling capability, and modern owned plant. Project highlights include NZ's largest solar farm at Kaitaia (Kohirā, 61,000 panels), Harapaki Windfarm (176 MW across 41 turbines), and NZ's first utility-scale BESS at Huntly.
Connell operates a project-based one-time contract revenue model, securing work through competitive tendering and long-term relationships with NZ energy owners and operators (Transpower, Genesis Energy, Meridian Energy, Powerco, Northpower, Lodestone Energy) and local government (Hamilton City Council, Waikato District Council, Tauranga City Council). Pricing is negotiated project-by-project and is not publicly disclosed. In March 2025, Connell joined the Northpower Group, reshaping its ownership structure and strategic alignment while preserving founder-led operating continuity.
