The aims of this study are to access the status and problems and draft possible solutions of Korean trawl fishery in New Zealand sea. The main target fish species for Korean trawlers in this sea were barracouta, blue mackerel, hake, hoki, jack mackerel, ling, oreo, orange roughy, southern blue whiting, spiny dogfish, squid and silver warehou. The Korean trawl fishery are suffering from a supply of seaman, continuous increasing coast of the counter partner, repair of vessel and seaman supply. It may be useful for getting over these difficulties to build a new trawler with a automatic operation system.
