The company behind the flawed Novopay system has sent a number of schools the wrong emails about yet-to-be-processed actions regarding their payrolls.
The Acting Secretary for Education, Peter Hughes, blamed human error for the privacy breach, which the Ministry of Education has reported to the Privacy Commissioner.
Mr Hughes says a Talent2 employee made the mistake when doing a mail merge and about 1600 schools are involved. The emails were supposed to be a proactive way of advising schools of payroll changes that are being worked on.
"In simple terms, the pay administrators at these schools have received the names and Ministry of Education numbers for staff at another school, instead of their own, along with the transaction number for the outstanding issue," said Mr Hughes.
He said 5600 transactions were covered in the emails. Of these, 3400 identified an individual and about 40 of those had other limited personal information such as the dollar amount of an advance or underpayment, information about a relationship with another agency or circumstances such as parental leave.
