An amendment from councillor Chris Fletcher to split Ports of Auckland's business from land ownership, which would involve selling the business and council keeping the 72ha of port land, was lost by 17 votes to five.
"I believe the land on which the port sits must be held by the council for the future. It is a strategic asset and should not be sold," Fletcher said in an email to councillors.
"The business of the port is another matter. I passionately believe that business, the commercial operation, should be separated. This could provide fresh investment, creating a better platform for efficiency and competition. I know that many small Auckland investors would welcome an opportunity to invest in their port," she said.
Said Mayor Phil Goff: "If you were wanting the sell you couldn't choose a worse time to sell than right now because the future of the port is not clear."
He was referring to Government plans for an upper North Island port study.
