OS Group is a family-built business with deep roots in the Far North. Founded by the O'Rourke family, we've spent years delivering civil construction and tree management projects that communities across Northland rely on every day from roading and earthworks to vegetation clearing and public spaces.

We are Northlanders working hard for Northland. We're not a big Auckland firm parachuted in. We live here, we work here, and we're invested in the future of this region.

Our current area of operation covers Te Taitokerau from Cape Reinga to Wellsford, with bases in Kaitaia, Kerikeri and Dargaville — meaning our teams can mobilise rapidly across the Far North.
