One of New Zealand's biggest export fish species, hoki, has shown a significant recovery after several years of low numbers.
Revenue of about $150 million per year is generated by hoki exports.
Latest research from the Ministry of Fisheries shows hoki stocks off the west coast of the South Island in particular, are now within sustainable target levels.
MAF chief executive Wayne McNee says reductions in catch limits in recent years have helped rebuild the stocks.
There have been progressive cuts, from 250 tonnes in 2001 to 90,000 tonnes in 2007.
Mr McNee says catch limits are now likely to be reassessed, in light of the recovery.
