Operations resumed at 7.30am, but the wharf closure has disrupted both the Interislander and Bluebridge services.
A Bluebridge spokeswoman said there will be “significant delays” to its sailings due to the port incident.
The Interislander’s Kaiarahi was due to depart from Picton early this morning but is now due to depart mid-morning.
Today’s disruptions follow delays yesterday due to heavy swells in Cook Strait, with both operators also hit by delays due to breakdowns earlier in the year.
“Capacity is really tight at the moment, but we are working with our customers to get them to their destinations as soon as possible,” said Rushbrook.
