Further to reply 24306 (2026), why was delivery of the Northwestern Busway split from one delivery agent to two, being Auckland Transport and the NZ Transport Agency?

Answer

New Zealand Transport Agency (NZTA) and Auckland Transport (AT) are jointly delivering the Northwestern Busway programme. The transfer of some responsibilities from AT to NZTA for the Westgate Station and Brigham Creek land components of the programme followed time and cost increases and agreement to change the scope of the works. It was considered that NZTA were better placed to deliver the rescoped works.
