The 30-year-old Cook Strait Interislander Arahura ferry missed a return sailing early on Saturday morning after losing propulsion in one propeller shaft as it approached its Aotea Quay berth.
KiwiRail spokeswoman Sophie Lee said the fault was identified shortly after the ship berthed.
"Due to the need to conduct testing the 2:25am (from Wellington) and 6:25am (from Picton) sailings were cancelled," Miss Lee said.
Arahura's scheduled Saturday sailings at 10:25am from Wellington to Picton and the 2:25pm from Picton to Wellington went ahead.
Trouble struck Arahura just two days after sister ship Aratere returned to service following a three-day mechanical failure layoff in Wellington.
