Corrections Minister Judith Collins says prisoners who may have spent more time behind bars than they should have due to a massive sentencing botch-up should not expect an apology.
The Government is also ruling out compensation, but law changes are likely after the Supreme Court ruled the Corrections Department has been miscalculating prison sentences.
"Actually I think the people who should be apologised to are their victims," Mrs Collins says.
Twenty-one prisoners will be released early, and there will be more, after the court found that the time someone spends in remand should be counted towards their overall prison sentence.
Corrections is confident it can cope with the early releases, but some lawyers say they will be seeking compensation for their clients, including Douglas Ewan, who says one man spent an extra three months behind bars.
"I don't think it's appropriate at this stage to put a dollar figure on it."
