Clarification on City Centre Future Access Study

Clarification in response to prior media release: 13 December 2012 

Auckland Transport has provided technical clarification in response to questions, comments and assumptions made after today’s release of the City Centre Future Access Study

  • The reference base case included all transport projects in the Auckland Plan including the Additional Waitemata Harbour Crossing, Waterview, SH16 and Puhoi to Wellsford and the Study therefore represents a best case scenario of the problems of access.

  • The Study provides a comparative assessment of options which were agreed with Central Government. The Benefit Cost Ratios (BCRs) reflect the comparative benefit of the options; they are not a business case evaluation.

  • The Study used Statistics New Zealand medium population growth projections agreed between local government and the Ministry of Transport, NZTA and Treasury.

  • The models used to inform the Study are the same as those used on a number of major projects such as Puhoi to Wellsford, Waterview and the Additional Waitemata Harbour Crossing.

  • The comparative BCR assessment took into account the assessment of Wider Economic Benefits (WEBs) as is common practice for large infrastructure projects. If these WEBs are excluded, the comparative BCR for the City Rail Link option would still be more than four times better than the next option of surface bus. 

  • The Study considered a total of 46 options including light rail, mobility pods, ferries and multiple bus and rail options. They were refined using multi criteria analysis to reach agreement among central and local government agencies about those shortlisted.

  • The Study was designed to select the best option, not to justify funding. The next step in this process is a detailed business case in which the options will be optimised and the fundability of the project fully worked through in a considered manner.
