A 33-year-old man has been arrested after Cook Strait ferry services in Picton were affected by a bomb threat.
This morning, a Cook Strait ferry sailing from Picton was delayed while the bomb threat was investigated by police.
Both the Interislander and Bluebridge ferries berthed in Picton were searched.
All passengers were disembarked from both ferries.
Marlborough Area Commander Inspector Simon Feltham earlier said a third Bluebridge ferry sailing to Picton this morning would be searched if required.
He said this afternoon charges were still being considered against the man, who was expected to appear in Blenheim District Court tomorrow.
"We appreciate today's incident caused considerable disruption and distress for many," Feltham said.
"I would like to acknowledge our Specialist Search Group staff who flew from Wellington to complete an extensive search of both the terminal buildings and ferries, and the investigation team who identified and located the alleged offender."
