The future of Auckland's port will be looked at in a new report, which will consider everything up to shifting the entire operation to a new location.
The final scope of the Auckland Council-commissioned study shows it will weigh up the merits of options ranging from little change, through to building a new port entirely some time in the next half-century.
Rick Boven - who is the chair of the working group overseeing the eight-month review - said external consultants would be chosen in coming weeks and will start work in November.
The study was commissioned after heated debate over plans by the council-owned Ports of Auckland to extend two wharves further into the inner harbour.
The company changed its mind over one extension, and decided to delay plans for the second after the resource consent was found to have been wrongly granted.
The Auckland Council will consider the study and the working groups recommendations mid next year.
