What was the net present value comparison between the Northway consortium's price for the Warkworth to Te Hana project and the Public Sector Comparator for that project before any risk adjustment was applied to either figure, and on that unadjusted basis was the PPP more expensive or less expensive than conventional public sector procurement?

Answer

This information has been withheld as it forms part of the commercially sensitive financial and risk modelling used to evaluate bids and assess value for money. Disclosure of the unadjusted pricing and Public Sector Comparator assumptions would reveal information about project costing methodologies, bidder pricing strategies and risk allocation assumptions, which could prejudice NZTA's commercial position and affect future procurement processes and negotiations.
