A strike at the Ports of Auckland has been delayed by a day, as mediation talks with the Maritime Union continue over collective contracts.
More than 300 port workers were due to resume strike action on Thursday night for two days, after four days of industrial action earlier this week.
Ports of Auckland chief executive Tony Gibson says mediation talks have progressed and the strike scheduled for Thursday night has been put off until Friday night and will now only last one day.
Mr Gibson says the change has come too late to stop four ships being diverted to Tauranga and too late to roster on more staff for Thursday night.
Talks between the port and the union will continue on Friday.
