About CPB Contractors

CPB Contractors was originally founded in 1949, but the name CPB Contractors was only launched in January 2016 following a merger of the CIMIC Group construction businesses of Leighton Contractors and Thiess Construction.

The company operates in Australia, New Zealand, Asia, India and Papua New Guinea and is involved in the construction of roads, rail, tunnels, defence, buildings and resource infrastructure.

Significant Projects

Transmission Gully – New Zealand

The $850 million Transmission Gully motorway is the first roading project to be delivered through as a Public Private Partnership (PPP) by Wellington Gateway Partnership in partnership with the New Zealand government.

The 27km four-lane motorway includes 29 bridges and is expected to open in 2020. The project is very complex with steep terrain requiring large-scale earthworks.

25 new structures equating to a total length of more than a kilometre will be constructed along the route. The largest of these, the Cannons Creek Bridge, will stretch 230 metres in length and sit 60 metres above the valley floor.
