The hacker Rawshark has rejected claims Facebook conversations between Papakura MP Judith Collins and blogger Cameron Slater are forgeries.
Instead, he has accused the pair of trying to spin their way out of the Dirty Politics storm.
The former Justice minister ramped up the stakes by accusing the hacker of creating forged conversations when quizzed over comments attributed to her and Slater.
The alleged conversations purportedly showed Ms Collins involved in conversations about the release of controversial SIS information before it was made public, and the possible leaking of police evidence.
She had she had "no record" of the conversations and told the Herald "you are likely to have been taken in by a criminal".
