International Transport Workers Federation Graham Mclaren said on October 21, the vessel was inspected by officials on behalf of Liberia, which have contained the ship until the crew's wages had been sorted out. The ship carries a Liberian flag.
The crew, made up of a captain, engineers, naval officers, electricians and able seamen and cadets, were owed more than $100,000 for the two months.
The Port of Tauranga confirmed the company had kept up-to-date with payments to dock, paying the port more than $90,000.
Mr McLaren said the Romanian crew was aware of the payment problems the previous crew had encountered. Another two engineers were needed before the vessel could sail.
Maritime Branch President for Tauranga, Peter Harvey said the problems experienced by the crew of Vega Auriga were common in the shipping world.
"These sort of complaints come up every few months, a complaint over wages. I've done dozens of them. Once they are away on a ship in a foreign country and have a problem. Where do they go to get it resolved? That's the whole problem these seamen face, they are very vulnerable," Mr Harvey said.
Nautilus Shipping Agency's Belinda Snell, the representative for the owner's agent, said the owners were still trying to arrange the ship's next voyage.
The Vega Auriga's estimated departure date is November 20.
The owners of the Vega Auriga did not respond to emailed questions.
Background
Earlier this year, 21 crew members serving on the Liberian-flagged vessel, Vega-Reederei, organised a picket line at the Port of Long Beach in California to protest their employer's failure to pay them for up to four months of back wages. The crew of mostly Filipino nationals also had to seek assistance from the International Transport Workers' Federation and support from dock workers belonging to the International Longshore & Warehouse Union.
