Additional Waitemata Harbour Crossing - preliminary business case report

The government’s National Infrastructure Plan highlights an additional Waitemata Harbour Crossing (AWHC) as an important priority to support the growth of Auckland. The NZ Transport Agency (NZTA) commissioned a study to provide information and analysis to assist all stakeholders to form opinions and consider options: bridge or tunnel; timing; and funding.

NZIER worked on this study with PricewaterhouseCoopers, Beca, AECOM, and SKM (who undertook the transport modelling and the ‘conventional’ economic appraisal). Our role was to evaluate the full spectrum of national, regional and local economic benefits from the AWHC. We considered all of the emerging methodological developments involved with assessing such potentially ‘transformational’ infrastructure projects. We also appraised the relative economic costs and benefits from different crossing options in the possible areas primarily affected, particularly the Wynyard Quarter development

The overall study and preliminary business case aim to inform debate on the issues associated with each form of crossing. NZIER’s contribution to the study ensured the debate is based on robust analysis.
