The Government has increased the hoki catch limit by 10,000 tonnes, taking the limit to 130,000 tonnes per year.
The hoki fishery is New Zealand's third largest seafood export after mussels and lobster, valued at over $150 million a year.
Fisheries and Aquaculture Minister Phil Heatley says the fishery has rebuilt fully following declines in the 1990s.
Sealord owns 30% of the quota and says the increase is a victory for sustainable fisheries. The increase takes effect from 1 October.
However, Mr Heatley has made reduced catch limits for bluenose and two orange roughy fisheries - the Chatham Rise and the east coast of the North Island.
