Chris Cairns says he has had no contact with the International Cricket Council's anti-corruption unit.
Cairns spoke briefly with media at Auckland airport tonight after he had flown back from Dunedin where he had been commentating on TV during New Zealand's test against the West Indies.
Cairns, Lou Vincent and Daryl Tuffey are understood to be the three former Black Caps being investigated by the ICC over alleged match-fixing.
Vincent confirmed in a statement he was co-operating with the ICC.
But Cairns appeared stunned by today's developments, especially after he had won a high-profile case in the London High Court last year to clear his name against allegations made by Indian cricket powerbroker Lalit Modi.
Asked why his name was being raised again, Cairns said: "I'm unsure. With regards to what's happened I've said I've been through a very arduous process in England last year, that's on record, and I stand by that.
"With regards to what's occurred now, I'd just like to reiterate the fact that I've spoken to nobody from any of those anti-corruption or ICC."
Cairns said "my heart sank" when the allegations surfaced today.
He wanted to return from Dunedin to Auckland to be with his family.
