A woman with brain damage has claimed she was blackmailed by someone who was erroneously sent her medical information by ACC.
The woman said the man who received the file contacted her and threatened her over an eight month period and tried to extort money from her, the Dominion Post reported.
The Privacy Commissioner last month announced an investigation into privacy breaches by the Accident Compensation Commission after a client - Bronwyn Pullar - received the personal details of more than 6000 clients by email.
The Petone woman, who had suffered severe brain damage after having a severe reaction to an anaesthetic during surgery, said ACC had not taken the breach seriously.
She said the government department refused to pay to have her phone number changed and was doing little to have the file retrieved.
