What is the weighted average cost of capital for the Warkworth to Te Hana project at financial close on 30 July 2026, and does that figure take account of the Crown Capital Contribution and the $1.6 billion 10-year Crown loan to NZTA agreed by Cabinet in August 2025?

Answer

The weighted average cost of capital has not been disclosed because it is commercially sensitive. Releasing this information would reveal commercially sensitive information about the contractor's financing arrangements and risk pricing. It could prejudice NZTA's commercial position in relation to future public-private partnership procurements by revealing commercially sensitive information about financing assumptions, risk pricing and bidder market responses. The impact of introducing the Crown Capital Contribution on the price and risk of the respondents' proposals was considered through the RFP process.
