Ten Work and Income staff members have been sacked after two inquiries into breaches of privacy for beneficiaries.
The national review of the Ministry of Social Development was launched last December after an investigation into staff at the Manukau branch office.
Seven were dismissed for "appalling" breaches of the code of conduct which included improper use of private files belonging to family and friends, as well as inappropriate email use. An allegation that a staff member sold personal details of a client to a debt collection agency was not proven.
Janet Grossman, the head of Work and Income New Zealand at the time, then ordered a nationwide audit to assure taxpayers they could have confidence in the "integrity of our staff and the welfare system".
Last night, the ministry released under the Official Information Act a summary of the review, which checked 100 randomly selected staff.
