Large amounts of overseas money is reportedly being bet on ASB Premiership matches, sparking fears of match-fixing.
$50 million from over 200 Indian and Asian websites was placed on games in the competition, according to TVNZ.
However, New Zealand Football chief executive Andy Martin didn't see the influx of foreign money as a bad thing and told 3 News they have no reason to believe any form of match or spot fixing has taken place in ASB Premiership matches.
The increase in betting is thought to be due to increased live coverage of the league this year and that a small number of people have been caught pitch-side, delivering information to Asia to manipulate betting markets.
Martin said he was aware of occurrences of this practice, known as courtsiding, happening at ASB Premiership games.
NZF say they are monitoring matches and betting markets and are aware of any shift in betting patterns.
Players have been put through rigorous anti-corruption training to identify the signs and know what to do if approached.
