Key sticking points between management and the unions include fatigue management and a claim for a 4% pay rise across the board, backdated to July 2019. The port has offered 2%.
"It's gotten to the unique stage where the parties can't even agree what we don't agree on'', unions spokesperson John Kerr said.
The company's positive financial performance would also likely be a heated point of discussion at the meeting.
Port Otago today reported a 12% improvement in earnings to $49.3 million, announcing a dividend of $8.45 million payable to its parent, the Otago Regional Council.
The results also disclosed an overall increase of $100,000 in remuneration to its chief executive, Kevin Winders, to more than $610,000, including incentive payments.
The unions, which represent 250 of the port's workers, have had a ban on overtime from Saturday.
Port Otago chairman David Faulkner said the port wouldn't be making any statements until the "process ran its course".
