Watch staff having inadequate rest periods, a faulty navigation light and no common language among personnel were included in the list of problems found on board the Vega Auriga.
An inspection report supplied by Maritime New Zealand to the Bay of Plenty Times revealed a list of 14 problems on the container ship, which arrived in Tauranga on Sunday.
Deficiencies included rest periods for watchkeeping staff not conforming to minimum requirements, a lack of a common working language on board, corrosion on a life raft cradle and an oily rag bin in the engine room with no lids.
There were no local control procedures for the ship's Controllable Pitch Propeller, or CPP, which needs to be adjusted from the ship's engine room and bridge.
There was also a fault with a navigation light and evidence showing an Electronic Chart Display and Information System unit, known as an ECDIS unit, was being used for navigation purposes, which it should not be used for.
