Faiszer Musthapha said existing laws were inadequate to deal with match-fixing and other forms of cheating exposed in the Al Jazeera documentary.
The minister said the International Cricket Council (ICC) had advised him to legislate against the practice after three Sri Lanka officials were filmed agreeing to sway matches.
"I am getting new laws drafted for this purpose and I am also proposing a special police unit to enforce the proposed legislation," Musthapha told reporters in Colombo after returning home from talks with the ICC in Dubai.
Sri Lanka's cricket board has already suspended three of its employees -- two coaches and the curator of an international stadium -- after they were caught in the undercover sting by Al Jazeera.
The board has also lodged a complaint with police, who have launched a criminal investigation.
"Cricket's Match-Fixers", broadcast on May 27, suggested that England and Australia players had also been involved in match-fixing in India.
England captain Joe Root and Australia skipper Tim Paine have dismissed the allegations relating to their respective teams.
Musthapha was in Dubai explaining to ICC officials why a Sri Lankan appeals court last week suspended elections for top positions at the cricket board.
Former board president Thilanga Sumathipala is seeking re-election but has faced accusations of being linked to gambling. He denies the charges.
