"We have the earnings, but the revenue is deducted," he said.
The six month result was supported by a 10.4 per cent rise in container volumes to 470,928 TEUs (20 foot equivalent units), reinforcing Port of Tauranga's position as New Zealand's premier freight gateway. These gains were diluted by a 16.2 per cent decrease in log export volumes to 2.4 million tonnes from 2.8 million tonnes in the prior year.
Chairman David Pilkington said the port had delivered a strong six month result, especially in the face of the decline in log export volumes.
"Our strategy of extending the port's freight catchment across New Zealand continues to deliver results for shareholders and the country's exporters and importers."
Mr Cairns said the port was in an excellent position to continue to grow its cargo volumes as more exporters and importers recognised the value the hub port strategy delivered with reliable, fast and cost-efficient routes to markets.
"With the Tauranga harbour channel dredging proceeding well, we are on track to complete our contractual commitments with freight and logistics management company Kotahi by July, in order to see larger vessels starting to call at the container terminal by the end of 2016," he said.
"This is the final building block in our five year $350 million investment programme to prepare for larger ships, which have the potential to deliver annual savings of as much as $300 million to New Zealand shippers. In the medium term, with the arrival of larger ships, we will be handling significantly larger volumes of cargo per shipment. We are looking at every aspect of our operations to ensure that we are ready for the step change later this year."
