ACC claimant advocates say the corporation is obsessed with balancing its books and rehabilitating accident victims comes second.
They aren't surprised by revelations that case managers are paid bonuses to get people off the scheme.
Green Party MP Kevin Hague released documents on Thursday showing case managers have specific targets and their pay is tied to achieving those targets.
ACC Minister Judith Collins has confirmed that but says it is an incentive to get people back to work, which is a good thing.
Accident compensation lawyer John Miller says it is just another example of wrong priorities.
"Instead of rehabilitating people properly they get rid of them in a quick and dirty way just to make the books balance," he said on Friday.
"They're ending up on welfare benefits and ACC is protecting its coffers by shifting people anywhere they can."
The ACC Futures Coalition says the bonus scheme explains why some case managers are harsh and insensitive.
Spokeswoman Hazel Armstrong says Ms Collins must review everyone who has been taken off the scheme in the past year.
"What I believe she will find is that people who are declared to be `vocationally independent' are not actually in work, or are on an invalids benefit, or are working part-time."
ACC chief executive Ralph Stewart, who resigned last week and is leaving at the end of the month, says all the critics are wrong.
"No one can leave ACC unless they are rehabilitated first, it's not the other way around," he said on Radio New Zealand.
"The bonus recognises that the underlying driver for ACC is the quality of rehabilitation. The care of clients comes first."
Mr Stewart confirmed the number of long-term claimants had been reduced since the last election.
There were 11,615 in November last year and now there are about 10,500.
