Bluebridge Cook Strait Ferries will run limited services for the next two days while it repairs damage caused by one of its vessels crashing into to a wharf.
At 1am on Tuesday one of the company's ferries "clipped" the berth as it was docking in Picton.
The damage has caused significant disruption to ferry services across the Cook Strait.

On Wednesday and Thursday only two ferries will operate - one from Wellington to Picton, and the one the other way.
"The company has contacted passengers affected and rescheduled them to later crossings or offered them a refund," said StraitNZ's commercial manager Ed Menzies on Tuesday.
NZME reports the damage to the wharf on Tuesday left a ferry full of trucks unable to dock. Some of the trucks were carrying fresh produce.
