Motu Moie has maintenance builds with equipment, machinery and supplies necessary for the upkeep of the island. The maintenance garage contains a work bench, table saw, drill press, and various hand and machine tools for repairs and maintenance. The building roof extends over one side to cover the tractor. Solar power supplies electricity to all buildings, and there is a back-up generator for increased power during construction or in emergency. The water well and tower supply fresh coral filtered water.
