Chief executive Tony Gibson said the port had been operating in a difficult market environment. "We thought it was going to be a tough year, and so it proved, but we still increased profit and dividend," he said in a statement.
Lower iron and steel prices resulted in significantly lower iron sand exports. While this was partially offset by increased cement throughput due to Auckland's booming construction sector, bulk volumes were down 5.5 per cent, he said.
However, imports of cars, light commercial vehicles and "high & heavy" vehicles increased, keeping the total fall in bulk and break-bulk volumes to just 2.2 per cent Gibson said he expected to similar volumes in the current financial year.
He said the container industry was facing ongoing difficulties caused by ship construction outstripping trade growth.
"The resulting overcapacity has led to a significant reorganisation of shipping services internationally, which is also affecting ports," he said.
Twelve of the world's top 30 ports have reported volume reductions this year, Gibson said.
"In New Zealand, the changes have resulted in volume leaving Auckland. The situation is expected to continue," he said.
Global container throughput is expected to grow by only 0.3 per cent this year while shipping capacity will increase by 4.6 per cent.
"We are expecting our container volumes to be flat or fall this financial year," he said.
Looking ahead, Gibson said the company would continue to build its freight hub network.
Ports of Auckland is New Zealand's hub port for car and container imports.
The port handles around 100 cruise ships annually and each ship visit is worth about $1.5m to the local economy. The $54.3 million dividend payable to the city was worth the equivalent of 4.4 per cent of the average Auckland residential rates bill, or $103 per household.
