Detective Superintendent Catharina Gunne, Garda National Economic Crime Bureau said: "Match-fixing and corruption is a threat to all sports at all levels and undermines public confidence in the fairness of sport.
"It can allow organised crime to infiltrate sport in order to use it to make illicit gains or launder proceeds of crime."
Gardai are appealing to anyone who have information in relation to match-fixing or sports corruption to contact them.
They can make a report in confidence to the Anti-Bribery and Corruption Confidential Reporting line – 1800 40 60 80 or to their local Garda Station.
