The decision is drawing fire from the Problem Gambling Foundation.
Advocacy and Public Health Director Andree Froude said it was “really concerning” that the offshore operator would face no direct penalty.
The case emerged after MetroNews presented the PGF with evidence that university students were using Instagram to promote Rainbet through affiliate links and earning rewards when new users signed up.
Under New Zealand’s Gambling Act 2003, it is illegal to promote overseas gambling, with fines of up to $10,000 for those who breach the rules.
“It is the influencers or students that are paying the fines, but it is the gambling operators that are approaching them in the first place - they should be held to account and it’s disappointing that they’re not,” Froude said.
