Teachers are outraged at yet another embarrassing mistake with the school payroll system, Novopay.
This time, the private pay details of up to 530 employees at ten schools were able to be viewed by other schools.
Jan Tinetti's Merivale School is among an unknown number who got another school's report.
"We could see people's names. We could see the collective agreement or individual agreement that they belonged to. We could see all their pay rates, the hours that they were employed for. We could see everything," said Mrs Tinnetti.
