The Maritime Union's backing the Ports of Auckland board as its spat with the city's mayor continues.
Wayne Brown has continued his attack on the port's leadership, saying he's lost confidence and plans to replace the board.
Chairwoman Jan Dawson has fired back, saying the mayor's statements create uncertainty for those whose livelihoods and businesses depend on the port.
Mr Brown wants to see a plan by the end of March to move work from the ferry terminal to Bledisloe Wharf, with the end goal to cease car and container operations in the CBD.
Maritime Union's Auckland Branch Secretary Russell Mayn spoke to Corin Dann.
