Prize-giving would start each day at 5pm but fish had to be in the weighing queue by 4.30pm.
As in previous years the biggest snapper each day would be worth $2000, with $30,000 for the biggest overall and $10,000 for closest to the average weight for the tournament.
Supporters of the tournament include Far North Mayor John Carter, who said it was one of the biggest events of its kind in the Southern Hemisphere, and a big deal for the Te Hiku area.
"It's huge. It means business for accommodation providers, fuel retailers, cafes, bars, restaurants, sellers of fishing gear and rental car companies. There's nobody who doesn't get some benefit," he said.
The council estimated the event produced an economic turnover of $3.8 million in the Far North district.
The Snapper Classic was founded by the Brjlevich family in 1982. It fell over in 2010 when the new owner ran into financial difficulties but was revived, under a new name, by Mr Stewart, a printer, and Mr Collard, a publican and Far North District councillor.
Mr Stewart said they were grateful to Kaitaia's business community whose sponsorship made the event possible. The final weigh-in is at 5pm, March 19.
