There's been another privacy breach at ACC.
The corporation's chief executive Ralph Stewart confirmed on One News that confidential information about more than 100 clients was mistakenly sent to the wrong people last Friday.
Labour's ACC spokesman Andrew Little says New Zealanders need to be able to trust ACC to keep their information private.
"We live in a digital age, everyone's operating off computers, they're sending all sorts of stuff over computers, but you've got to do it right and ACC has to do it right more than anyone and they've got it wrong so many times.''

Mr Little says ACC needs to take a close look at its processes and address the issues.
"And I think for an organisation the size of ACC in this day and age, and certainly given the last few months where all their other errors have been brought to light, it's just unforgivable.''
Mr Little says ACC holds private information about New Zealanders, and clients should be able to trust the security of it.
