Ports of Auckland workers are set to strike for a full week in a new escalation of their long running employment dispute.
The just-announced strike action 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."
