Ports of Auckland says it will take decades to move the port to another city, so it needs a plan.
A 30 year draft master plan for the waterfront is being released today.
It includes a five storey carpark with a public rooftop park, as well as a 13 metre extension to Bledisloe Wharf.
Ports of Auckland CEO Tony Gibson said significant growth is happening in Auckland and the port could outgrow its current footprint, so they want to leave a legacy for Aucklanders if and when the port moves.
"What we're trying to do is with the port development is ensure that what we put on the port is iconic in nature and that therefore if and when we do move, we leave a legacy for Aucklanders.
"In the meantime, we need a plan and what we need to do is to ensure Aucklanders can get the the things on the shelves they need and expect."
