"These inefficiencies need to be addressed and it will only be through players in the industry working together that sustainable cost savings can be achieved," said Mr Greenough.
The port's board declared a fully imputed six-month dividend of 22 cents per share, up 4.8 per cent on last year's interim dividend. Revenue was $136.3 million, largely unchanged from the $137.1 million in the first half of 2014, with growth in container volumes and dairy and meat exports for the most part off-setting the impact of a drop in log volumes.
Chairman David Pilkington described the result as strong, despite the drop-off in log exports, and said the 2014 alliance with Kotahi was already driving increased freight volumes through the port.
First half export volumes dropped by 5.9 per cent overall to 6.4 million tonnes, largely due to a fall in log export volumes, which were down 17 per cent. However, the port handled 426,512 TEUs, up 11.9 per cent on the prior year, while total cargo volumes increased 1.2 per cent to 10 million tonnes.
Mr Cairns said he expected container volumes to continue to increase in the next six months.
