Ports of Auckland has reported a loss of $11.9 million for the year to June, a turnaround from the profit of $23.3 million it made the previous year.
The company, which is owned by Auckland Council, said the loss is due to writing down the value of land.
Operating earnings fell 6% to $54 million, which the port said was due to the loss of a shipping service and prolonged strike action which hit its container business particularly hard.
That offset an improved result from its break-bulk and vehicle division.
It paid the council a higher dividend of $20.1 million.
