Fishing contest organisers are scrambling to comply with a Department of Internal Affairs crackdown on spot prizes.
At least one family event - Beachland's Top Catch - has been cancelled. Organisers have said the red tape made it impossible to continue.
The country's biggest fishing event, Beach and Boat Ruakaka, is going ahead with significant changes. The Snapper Bonanza, held at Ninety Mile Beach, has spent thousands trying to set up a charitable foundation to apply for a licence to draw spot prize winners out of a barrel.
Only certain licensed organisations, such as the Lotteries Commission, charitable trusts and SkyCity casino, are allowed to run games of chance with big prizes. Sports tournaments and family events were being made to comply for the first time since legislation was passed nine years ago.
Last week, the Herald on Sunday revealed that had been set in motion after a complaint from a pokie trust.
