About this Fishery

This fishery is found on the western coasts of the North and South Islands of New Zealand, and was certified in 2011. The fleet comprises 175 vessels.

Albacore tuna is a highly migratory pelagic species. Mature fish spawn in tropical and sub-tropical waters between about 10°S and 25°S during the austral summer. Juveniles appear in surface fisheries in New Zealand at 1 year of age, from where they appear to gradually disperse to the north. Subsequently, there are regular migrations between tropical and subtropical waters. Albacore migrate south during early summer and north during winter.

Commercial albacore trollers in New Zealand tow 12-18 lines simultaneously from the vessel’s stern and from long outrigger poles mounted amidships. The line lengths or depths are adjusted to permit hauling of any one line without tangling or interfering with the others. The lines are either braided polypropylene, dacron or monofilament nylon and are hauled in by hand or by hydraulic haulers.
