At least one match involving the Auckland Aces provincial cricket team at the 2012 Champions League in South Africa is under the ICC's anti-corruption spotlight.

NZ police have held talks with the International Cricket Council to sign a formal information-sharing agreement before the 2015 Cricket World Cup.

The ICC anti-corruption panel is believed to be looking at matches involving NZ players that took place in India, S Africa and England, raising the possibility that criminal charges could follow.

Chris Cairns, speaking this evening at Auckland Airport, said he hadn't been aware of the allegations against him until today.

Former New Zealand batsman and former Wellington councillor John Morrison said he would be very disturbed and surprised if the allegations proved to be true.

New Zealand great allrounder Chris Cairns is one of three players being investigated by the ICC over allegations of match fixing.

NZ Cricket Players Association boss Heath Mills says match-fixing allegations make it a 'sad day' for the sport, and believes the onus is now on players to come forward.

The chances of test cricket returning to Auckland on a regular basis any time soon are slim.

Sri Lanka's World Cup captain Kumar Sangakkara has challenged former skipper Hashan Tillakaratne to prove his recent allegations of rampant match-fixing.
