Last year's fall in total trade of 0.3 per cent to 20.1 million tonnes was largely attributed to the 1 million decline in log volumes. The full year also saw exports decrease by 1.2 per cent to 13.1 million tonnes, while imports increased by 1.4 per cent to 7 million tonnes.
Meanwhile, container traffic continued to grow strongly last year, especially in imports, with lumber exports holding their own and pulp and paper exports up by five per cent in volume on the previous year, said Mr Cairns.
Last year dairy exports were up 22 per cent to just over 2 million tonnes, he said, adding that as result of the Kotahi collaboration Port of Tauranga now handled 99.5 per cent of Fonterra's North Island dairy exports. Kiwifruit has been the star performer, with export volumes increasing 21 per cent and expected to continue growing at a strong rate.
Chairman David Pilkington said the port expected its long-term alliances - with the likes of Oji Fibre Solutions, Kotahi, and more recently Zespri and Tauranga Kiwifruit Logistics - to continue to drive cargo growth, especially in container traffic.
"These initiatives also shelter us somewhat from swings in individual cargoes, such as last year's significant reduction in log exports," he said.
The port's $350 million investment programme to prepare for big ship arrivals, extensive land holdings in Tauranga, and rail-linked MetroPort facility in Auckland, had readied it for future expansion.
Mr Pilkington noted that the recent future port study, undertaken on behalf of Ports of Auckland, had suggested as an option a mega port on the Firth of Thames to accommodate Auckland and Tauranga cargo growth over the next 50 years.
"We have seen no economic justification for this idea, nor have we been privy to the assumptions that led to it," he said.
"What we do know is that we can significantly expand the volume of imports we can deliver into Auckland, without adding to traffic flows in downtown Auckland. Ultimately, we believe the market will drive any rationalisation required, and we are about to see the efficiencies that can be had from the arrival of bigger ships."
