ACC Minister Judith Collins says progress on opening up ACC to the private sector is still being made.
In a speech on Thursday morning, Ms Collins also said the corporation's biggest current challenge is client privacy.
The previous ACC minister, Nick Smith, had already embarked upon the process of allowing private insurance companies to compete with ACC for workplace cover.
He resigned last month after it was revealed he had written a reference for an ACC claimant while he was the minister.
Ms Collins, who took over the portfolio, told the Employers and Manufacturers' Association on Thursday that progress is being made, but the process will not be rushed.
She also talked about the recent controversies over the release of client information, saying they've understandably undermined public confidence in ACC.
She said she's still not satisfied the corporation's privacy provisions are good enough, and the board is working to address that.
