Aratere would still be conducting return freight crossings from Wellington to Picton at 2.45pm and 10.45pm today, he said.
A media briefing this morning would detail what was wrong with Aratere, Mr Flyger said.
Meanwhile, the company said it was not concerned about reports the Arahura hit the wharf at its Wellington terminal yesterday morning, reportedly due to strong winds in the capital.
"Vessels contact wharves fairly regularly especially in adverse weather," a spokesman said yesterday.
"There was no damage to either the Arahura or the wharf, and we've received no reports of injury to persons or damage to cargo as a result."
This morning Mr Flyger said the ship's master and linesman were "both pretty adamant" that the ferry did not make contact the wharf.
Both the wharf and the Arahura subsequently had been inspected and no damage had been found, he said.
