ACC Minister Judith Collins is welcoming an investigation by the Privacy Commissioner into a leaked email sent to her from former National Party president Michelle Boag.
The email contained information about ACC claimant Bronwyn Pullar, but Collins and ACC management have denied leaking it to the media.
Pullar was inadvertently sent an email from an ACC employee which contained the private details of 6700 ACC claimants, including victims of sexual abuse and other violent crime.
The leaked email had Boag's account of a December meeting where she and Pullar met with ACC management to discuss the privacy breach.
Pullar claims she promised not to divulge the personal details. She said ACC then leaked her name and details to the media, in an attempt to "destroy my privacy and reputation".
An ACC report to Minister Judith Collins claimed Pullar threatened to go public about the breach unless the corporation gave her a "guaranteed benefit payment for two years".
The new investigation could include forensic scrutiny of computers used by Collins and her staff.
Collins said she would be "very happy" for her computer to be examined.
Meanwhile, Labour is continuing to question the Government on who knew about the email.
In Parliament today, Labour MP Trevor Mallard asked if the contents of the Boag email were discussed with Simon Lusk, who has worked on campaigns for a number of National Party MPs.
Collins said Lusk has no involvement with the email.
"I'm just staggered by Mr Mallard's comments today," she told media.
"I'm not going to try and work out Mr Mallard's mind, I think he's still working it out himself."
