The New Zealand Cricket Players' Association is concerned that anti-corruption investigations continue to be played out in the public domain.
Revelations about Black Caps captain Brendon McCullum's match-fixing testimony were printed in UK media on Monday, following on from comments also published last week from former New Zealand batsman Lou Vincent.
Players' Association chief executive Heath Mills says it's unacceptable that written statements made by players to the ICC have found their way into the media.
Mills says it completely undermines any trust or confidence players may have in cricket's anti-corruption systems and processes given confidentiality is supposed to be central to the process.
Meanwhile a lawyer acting for McCullum says it is too early to consider any possible legal action after his match-fixing testimony was leaked to UK media.
