The Accident Compensation Corporation (ACC) is appealing against a court ruling which could force it to restore weekly compensation to about 170 people.
Most were suffering problems with injuries they received as children.
Dominique Vandy was forced to give up work last year when a hip injury from a horse-riding accident when she was 12 flared up.
ACC refused compensation because she wasn't working at the time of the accident, but in March a Hamilton District Court judge overturned that decision.
That contradicted another court ruling, which had been the basis for ACC stopping payments to 170 people.
ACC is now appealing against the Vandy decision in the High Court.
Call for payments in the meantime
A lawyer for the claimants, John Miller, says that losing the compensation has been disastrous for many of them, and that ACC should reinstate payments while the legal question is being decided.
A spokesperson for advocacy group Acclaim Otago, Bruce van Essen, says he hopes the ruling puts an end to any confusion.
ACC was wrong to stop payments when the law wasn't clear, Mr van Essen says, and losing compensation has been stressful for many people.
