A patrol of commercial fishing vessels off Northland's coastline found all crews were abiding by the strict regulations.
Ministry of Fisheries officers boarded 12 commercial boats off the region's coastline during a patrol last week targeting commercial vessels and found all had correct paperwork for their catches. Six recreational vessels checked during the four-day operation were also found to be abiding by the law.
Commercial fishers filing incorrect paperwork and catch returns can face fines of up to $250,000 and confiscation of their vessels.
Authorities are firmly setting their sights on checking those taking fish from along Northland's coastline and are promising more patrols will be carried out.
The operation, named Vixen, saw navy inshore patrol vessel Hawea take two fisheries officers from Whangarei Harbour to the North Cape and back.
