ACC chairman John Judge is calling on whistleblower Bronwyn Pullar to release evidence to back her claims the Corporation "deliberately attempted to destroy her privacy and reputation".
Pullar herself is the subject of a police complaint after ACC accused her of threatening to go public with personal details of more than 6000 claimants inadvertently emailed to her, unless the Corporation guaranteed her a benefit for two years.
She disputed ACC's claims and yesterday said she had "solid grounds" to make a complaint to police herself "given the false assertions and the contradictory evidence" the Corporation had released about her "in an attempt to defame" her.
Pullar has claimed ACC deliberately leaked her name and details of her ACC case, which followed a cycling accident in 2002.
Judge this morning said he had "absolutely no idea" how her name appeared in the media.
"I don't think it had anything to do with ACC at all, as far as I'm aware," he told Radio New Zealand.
"If she has evidence that has happened, I would be pleased to get it and we will deal with the issue."
Judge said he was confident ACC had acted properly.
"If that is how she feels and she wants to make a complaint to police, that is her right to do so."
Although Nick Smith, who was minister of ACC until last December, wrote letters supporting Pullar on a ministerial letterhead, Judge said he was confident he had not done so for any other claimant.
Smith resigned his ministerial warrants on Wednesday after the letters and details of his friendship with Pullar became public.
Judge said Smith had not attempted to politically influence ACC.
"At no time in any of the discussions I've had with Dr Smith was he ever been other than straightforward.
"We had no discussions at any time about claimants issues."
Judge apologised for the privacy breach on behalf of ACC but said "very little" information had been released to Pullar.
He echoed comments by ACC Minister Judith Collins yesterday that "the proper thing" to do when someone was mistakenly sent information they weren't entitled to, was return it.
Labour and the Greens have written to the Auditor-General Lyn Provost, calling for an inquiry into the matter.
Judge said ACC would fully cooperate which any such inquiry.
