New Zealand Signs Public-Private Partnership Agreement for Northland Expressway

The New Zealand Government has signed a public-private partnership (PPP) agreement for the Warkworth to Te Hana section of the Northland Expressway, marking one of the country's most significant infrastructure projects.

The Northway consortium will design, build, finance, maintain, and operate the 26-kilometer, four-lane expressway with grade-separated interchanges at Warkworth, Wellsford, and Te Hana. The project includes 15 standard bridges, two underpasses, numerous large culverts, 12 wetland stormwater treatment basins, and twin tunnels of around one kilometer through Kraack Hill.

The final project cost has a net present value (NPV) of $3.649 billion, which is approximately $251 million below the Public Sector Comparator approved by Cabinet in March last year. Every dollar invested is expected to return $1.60 in wider economic benefits to New Zealand.

Transport Minister Chris Bishop said the PPP represents good value for taxpayers and that lessons from previous PPPs have been incorporated, including a more sophisticated approach to allocating risk and securing property and resource consents earlier.
