Another member of the Auckland Transport board has resigned, the third since mayor Wayne Brown took office.
Dr Jim Mather is leaving, and say his approach to governance is not well aligned with some of the new leadership in council.
Since then, Auckland Council has appointed councillors Mike Lee and Andy Baker as directors of Auckland Transport.
The mayor has previously said he will continue to push for Auckland Transport to come back under council control, assigning councillors to the transport committee in hope of solving the cities transportation woes.
Last month, Brown said Auckland Transport needed to completely change its approach to better serve its communities.
In a letter sent to AT acting chairperson Wayne Donnelly, Brown said the council-controlled organisation should seek to understand how Aucklanders lived now and how they wanted to live in the future.
"AT must understand the families who are struggling to move around the region: Pick-up their children, do the groceries, get home safely after-dark, and juggle other commitments.
"You must understand the local businesses who rely on transport connections and their needs now and in the future. And you must recognise that the transport network materially impacts Aucklanders' safety - especially at night, for women, for young people, the elderly and for shift workers."
The agency needed to consider people did not always have the option of public transport and required roading and carparking networks, he said.
