Harbourmaster Grant Nalder told the Herald the ferry had “made contact” with a linkspan, which is the dock ramp that allows vehicles to access the ferry.
The hull was damaged, he confirmed, but well above the water line and there were no injuries or oil leaks.
KiwiRail said in a statement the incident happened at 3.30pm while Aratere was docking in strong winds.
“As a result, there has been some damage to the linkspan, and to the hull of the vessel well above the waterline.
“No one was injured and there is no danger to the ship, passengers or the environment as a result of this incident.”
The ferry had 106 passengers and 40 crew on board. Passengers and vehicles were able to exit the ship. Aratere’s 4.30pm sailing from Wellington was cancelled.
Interislander Executive General Manager Duncan Roy told the Herald repair work to the Aratere and the linkspan will continue overnight.
“We anticipate Aratere returning to service over the weekend. Affected passengers are being transferred to alternative sailings,” he said.
Transport Minister Simeon Brown told Newstalk ZB Drive host Heather du Plessis-Allan he had been on the phone with KiwiRail chief executive Peter Reidy tonight.
Brown said there were high wind conditions in Wellington but there were several other things KiwiRail would be looking into including “whether or not they were entering a particular course correctly”.
“We’ve been making our point very clearly around the operations of that organisation. They need to be lifting the game and that’s why we’re refreshing the board and setting very clear expectations.”
Asked whether he was pulling his hair out over KiwiRail, Brown said: “Well, yes.”
As recently as Tuesday, Aratere’s 5.30am sailing departing Wellington and its 11am return service were cancelled due to a fault discovered during pre-departure checks.
Roy told the Heraldthe fault was due to a technical problem involving a pump.
It was fixed in time for sailings to resume by 4.30pm that day, Roy said.
He confirmed they were also waiting on a part for Aratere’s gearbox for a pre-emptive replacement.
“I look forward to working with KiwiRail’s shareholding ministers, board, management, staff and stakeholders and supporting the company in implementing its plan to increase efficiency and deliver exemplary safe and reliable customer service,” Jager said.
