No-one on the bridge of the Aratere knew how to over ride a new auto pilot system as the ferry hurtled towards the shore shortly after leaving Picton on Friday June 21 with 47 passengers onboard. No one was injured, but the Aratere, the only rail enabled interisland ferry, couldn't be refloated until after high tide the following day. Today, the Transport Accident and Investigation Commission or TAIC published its interim report on the incident. It said the ship had a new steering system and the Ship's master getting familiar again after a spell on another ship, TAIC Chief Investigator of Accidents Naveen Kozhuppakalam spoke to Lisa Owen.
