The troubled Novopay system has hit another glitch, with a number of education staff reporting problems with their payslips.
New Zealand Educational Institute President Judith Nowotarski told ONE News she was first alerted to the problem yesterday afternoon by members who had problems with their pay.
She says she also received an email from the Ministry of Education when they detected an "issue" with the payment software.
"Overnight things would have escalated as more of our members, teachers and support staff, would have gone home and be looking at their pay slips," she says.
Ms Nowotarski is unsure how many education staff have been affected but she believes the problem will escalate.
The Novopay software had been plagued with problems since it was rolled out in August 2012. Nearly $20 million has so far been spent trying to fix it.
Talent2, the contractor tasked with implementing the system, drowned in technical difficulties and an increasing backlog of errors, a 2013 study found.
Ms Nowotarski is renewing calls for the Government to fix Novopay once and for all.
"It's a bit of deja vu. It's 12 months down the track and we are looking for a final end to all of this," she says.
"All they need to do is fix it."
