Ports of Auckland workers are set to strike for a full week in a new escalation of their long running employment dispute.
The strike action, announced today, is set to start at 7am on February 24.
It is in addition to a partial strike set to take place from February 15 to 22.
Maritime Union National President Garry Parsloe said the new industrial action was a response to the "imminent threat" to workers' livelihoods.
"The port company is planning to make our members redundant and contract out their jobs. This casualisation exercise is a direct attack on conditions of work and secure, permanent jobs."
The strike will be the latest in a running battle between port management, who want to cut costs by increasing use of casual labour, and the union.
The dispute has cost the transport hub contracts with shipping line Maersk and dairy exporter Fonterra.
Ports of Auckland has threatened to outsource workers' jobs amid the continuing strike action.
Parsloe said the port company management did not understand the consequences of their "extreme" course of action.
"It is an attack on the port workforce and their families and is bringing the future of the Ports of Auckland into grave danger."
Ports of Auckland workers have been handing out pamphlets making the case for their industrial action at transport hubs such as Britomart.
