"What this does reinforce is the need for external capital for port development as funding 6 Wharf would now be an even bigger hurdle for ratepayers.
"We are fully committed to our original objectives: supporting the port to invest in its growth, de-risking the council's investment portfolio, retaining majority ownership and control of the port and protecting ratepayers from Port development costs."
Napier Port chairman Alasdair MacLeod said the port's objectives remain focused on delivering an infrastructure asset to serve Hawke's Bay.
"6 Wharf is a highly strategic, intergenerational infrastructure asset that will ease increasing constraints at the Port and put it in a better position to respond to any future growth."
