The Auckland Chamber of Commerce is supporting a halt of work on two large wharf extensions into the Waitemata Harbour.
Chief executive Michael Barnett said the issue should not be decided in an emotionally fired environment that placed interested parties against one another.
Ports of Auckland confirmed on Monday it was proceeding with work on the extensions at the end of Bledisloe Wharf.
The decision to continue work comes despite public protests and a political call by Auckland Council to halt work until until a wide-ranging port study is done.
Mr Barnett said the ports company should stick to the current footprint until the wider community is better informed and understand why any change should occur and the consequences.
