What is the estimated total construction cost of the Warkworth to Te Hana section of the Northland Expressway, and what proportion of total construction cost does that represent?

Answer

The overall Net Present Value (NPV) cost of the Warkworth to Te Hana Project is estimated at $3.649 billion. This includes the Unitary Charge payments from NZTA to the Contractor during the 25-year operational period, NZTA’s client-side costs to manage the contract and the Crown capital contribution. In nominal terms the design and construction costs for Section 1 is estimated at a nominal $3 billion over the construction period from 2026 – 2034. This is paid for by the PPP Contractor and the NZTA through the Crown Capital Contribution.
