If the prize exceeds $5000 in value the society running the competition needs a licence.
"Organisers say that because the primary purpose of their event isn't gambling and the potential for harm is minimal the requirements imposed are too harsh," Mr Tremain said. Problem Gambling Foundation chief executive Graeme Ramsey said common sense was needed on the issue.
The gambling risks for people involved in spot prizes was "absolutely minimal", he said.
"We think the current regulations are a bit foolish.
"Anything that encourages families to be together at these events has got to be good by us."
Dave Collard is one of the organisers of the Captain Morgan Snapper Bonanza surfcasting competition at Northland's 90 Mile Beach.
In a week-long competition that ended last Saturday, they offered $130,000 worth of spot prizes.
He said the regulations meant the prizes had to be classed as a raffle.
"That's like putting a square peg into a round hole, it just doesn't go."
The spot prizes were one of the things to encourage people to enter the competition, Mr Collard said.
He embraced any changes that would cut the red tape around the prizes.
Mr Tremain said a discussion document was necessary because changes to spot prize regulations were required.
"I am looking forward to hearing feedback from event organisers and members of the public," he said.
