What credit margin over the base rate applies to the senior private debt raised by the Northway consortium for the Warkworth to Te Hana project, and what is the resulting all-in senior debt cost at financial close on 30 July 2026?

Answer

The credit margin over the base rate and the resulting all-in senior debt cost at financial close have been withheld as they form part of the project's commercially sensitive financing arrangements. Disclosure could prejudice NZTA's commercial position by revealing the contractor’s financiers' pricing and risk assessments, and could adversely affect future NZTA procurement processes by providing prospective bidders and financiers with insight into commercially sensitive market information.
