Article covers the revelation by the New Zealand Transport Agency (NZTA) regarding the cost of the Transmission Gully project in Wellington. They testified to a parliamentary committee that a public-private partnership for this project would cost the taxpayer three times more than if the agency built the road itself. Supporters maintain that the higher cost is worth it because the road will be completed sooner, especially since NZ is currently struggling to find public funding for highway and road projects. Examines the proposed P3 arrangement and the estimates of what it would cost for NZTA to do the road itself.
