The Auditor-General is expected to make a decision on whether to launch an inquiry into privacy breaches at ACC by Easter.
About 9000 ACC records relating to about 6700 individuals, including a number of clients with sensitive claims - injuries resulting from sexual abuse or sexual assault - were accidentally released to claimant Bronwyn Pullar last year.
A spiraling controversy over the release has seen former ACC minister Nick Smith over conflict of interest breaches in his handling of Ms Pullar's case.
The auditor general this morning revealed a request for an independent inquiry into ACC was being considered.
The Auditor-General's office said the investigation would require a significant investment of time and public funds.
"We need to make sure we understand the issues, the work being done by other agencies, and what value we could add before we make a decision.
"We expect to carry out the preliminary work needed to make that assessment in the course of next week and to make a decision before Easter."
