This information is for new applicants for MNZ certificates of competency for Marine Engineer Class 5 (MEC 5), Marine Engineer Class 5 – Steam (MEC 5 Steam) and Marine Engineer Class 5 – Motor and Steam (MEC 5 Motor and Steam).

MEC 5 and MEC 5 motor and steam certificates correspond with a certificate issued under regulation II/5 (chapter 2 regulation 5) of the International Convention on the Standards of Training, Certification and Watchkeeping for Fishing Vessel Personnel, 1995 (STCW-F)

You can get a MEC 5 certificate for work on board motor or steam ships, or on both. (A motor ship has diesel main propelling machinery.) Your sea service and training must be appropriate for the type of propulsion power, and your certificate will state the type and size of main engine propulsion power you are qualified to operate on.
