Flow-on employment from people who benefited from the port and its employees multiplied to a total of 2900 jobs.
The latest University of Waikato update of the port's economic impact said business activities associated with the port made up 51 per cent of the Bay of Plenty's economic activity.
Its impact on the Bay of Plenty totalled nearly $14 billion when revenue earned from port operations was added to the value of imports and exports handled across the wharves.
Dr Warren Hughes of Waikato University then added the impact of the port on the rest of New Zealand and found it totalled $27.7 billion.
The added value generated by the port totalled $10.8 billion or nearly 6 per cent of New Zealand's gross domestic product (GDP).
His report published in November 2010 found that the Port of Tauranga's exports were almost three times its closest competitor, the Ports of Auckland.
"Major exporters already favour the Port of Tauranga over Ports of Auckland by a three to one margin. Accordingly, any constraint on the port's development also puts at risk cost-effective exporting by New Zealand's most important exporters,'' he said.
Mr Cairns said group net profit had increased by 87 per cent since the global financial crisis began in July 2007.
Freight diverted to the port from industrial action at the Ports of Auckland contributed less than a third of the increase in containers.
Industrial action saw volumes peak at 82,000 containers in March _ 80 per cent up on a year earlier.
He said container volumes had eased since March to just under 70,000 units in June_still nearly a third more than June 2011.
Mr Cairns said the way the port and KiwiRail handled the pressure generated by Auckland's problems gave him even more confidence that the $180 million port expansion over the next years would prepare the port for its next period of growth.
The expansion focussed on dredging to handle the next generation of container ships and the expansion of the container terminal including buying two new cranes costing $13 m to $15m each.
The record result coincided with the 20th anniversaries for the port _ its listing as a publicly listed company and the establishment of Sulphur Point.
