Prime Minister John Key and ACC Minister Judith Collins have refused to back ACC's most senior executives in their dispute with claimant Bronwyn Pullar but do not want to speak more before two inquiries are completed.
Mr Key said there were "genuine questions" over statements made by Accident Compensation Corporation leaders about the organisation's police complaint against Ms Pullar. The corporation has come under new pressure after Ms Pullar released a secret recording of a meeting with ACC to TV3's 60 Minutes which appeared to show she made no threats.
The corporation last week insisted Ms Pullar had threatened to make public thousands of accidentally released client files despite the police clearing her of any offence.
Asked about the ACC's complaint to police, Mr Key said: "I can't answer those questions about whether the complaint was accurate or the basis for that complaint. They are valid questions but you need to direct those to [the ACC chairman] or the minister."
He later added: "There's some genuine questions that would need to be answered about the rationale for the statements that were made by executives at ACC."
