ACC will be making a decision on whether its introduction of an automated claims system will lead to job cuts.
The organisation has switched from paper-based systems to digital processing of claims.
Most claims will now be automatically accepted, removing the need for staff to assess each individual claim.
ACC's chief operating officer Mike Tully said none of its 24 sites would close but he was not ruling out future job cuts.
Any such decisions will be made in the New Year.
Mr Tully said the new system was launched last month and in its first week it automatically accepted 60 percent of the 33,000 claims received.
He said ACC's data collection from previous claims helped the new system to understand how to process claims faster.
"Claims that follow a generally normal path, which are vast majority of all claims, [the new system] can auto-accept so that there are no confusions and it speeds up the time for reactions and speeds up the time for getting an effective outcome for New Zealanders."
Under the new system, he said claimants would be able to recover faster because they could access the right type of support sooner.
"So this way New Zealanders can interact over the internet, through mobile, through apps ... to [see] what is happening with their claim."
He said the new technology would also speed up the wait for acceptance letters.
"It can take up to a week for acceptance letters to arrive, [but] with technology and with the way we're moving you'll be able to receive that within minutes."
He said ACC would use data collection from previous claims in the new system to
No claim will ever be automatically declined by the system, he said.
