Around 2,000 protesters set out from Britomart this afternoon in a show of support with Ports of Auckland workers.
A boisterous and determined mass of marchers waved signs saying: "Len Brown is a scab", and a multitude of flags, indicating international support the workers have received.
It came as Sydney wharfies went on strike in a show of solidarity with the Maritime Union of New Zealand workers, who were sacked by the port last week.
The march headed off from to the strains of Dave Dobbyn's Loyal on its way to the port site a kilometer away.
Despite the numbers, former left wing MP Willie Jackson described the turnout as "disappointing"
"The union movement has to really get out and support these guys," said Jackson.
