"The other aspects just seem to be a general lift in economic activity and as a result, we had the two best months we've ever had," Ball said.
Andy Bowley at Forsyth Barr said latest Ministry of Transport data showed Port of Tauranga container numbers fell 13 per cent in the September quarter, exacerbated by Fonterra's food safety scare, compared to Ports of Auckland volumes rising 11 per cent.
"We expect Port of Tauranga to continue to lose share to Ports of Auckland through the remainder of 2014," Bowley said.
Port of Tauranga has traded at a premium to the market and that was expected to continue due to the company's high returns, longer-term growth outlook, capital management potential, strong management team, operational execution capability and conservative balance sheet.
"While the longer term fundamental story is attractive, near term challenges and valuation constraints are reflected in our hold rating."
Mark Cairns, Port of Tauranga chief executive, confirmed the numbers and said more details would emerge next month when the interim results are released on February 20.
On Monday, Cairns announced a conditional deal, worth about $20 million, to buy 15ha of Rolleston land south of Christchurch to create a new freight village, railing then shipping goods out of PrimePort Timaru.
Tauranga shares climbed from $13.50 on Monday to close at $14.60 yesterday.
"The market obviously liked the news and sees some prospect for further growth. We have to make it work now," Cairns said.
Mark Lister, head of research at Craigs Investment Partners, described the Rolleston deal as a positive and sensible long-term move.
