"The Ministry for Primary Industries says exports alone are expected to reach $2.3 billion by 2025," Dr Helson said.
"Add the contribution to the domestic market through jobs, investment in infrastructure and the sectors supporting the industry and you have a significant contributor to the New Zealand economy."
The report, which used catch data from the Ministry for Primary Industries, measured a five-year average, showing 13,468 people directly employed in fishing and seafood processing - 0.7 per cent of New Zealand employment.
Seafood is New Zealand's fifth-largest export commodity by value and represents 3.2 per cent of total exports.
The report included fishing and seafood harvesting but excluded aquaculture, which has revenues of $500 million.
"In the inshore fishery, snapper is the top commercial catch, and rock lobster and paua the highest value shellfish species," Dr Helson said.
The largest, deep-water commercial catch was hoki, accounting for 38 per cent of the revenue from deep-water fisheries.
"It is about jobs - and particularly jobs in regional New Zealand. The better the industry does the better off fishing communities are around the country."
Nationally, the seafood-processing industry had greater employment than the fruit and vegetable-processing industry and similar employment numbers to the pipfruit industry.
