Northland school principals have been invoicing the Ministry of Education for time spent trying to sort out the Novopay payroll system.
Pat Newman, from Hora Hora School in Whangarei, said he first invoiced the MoE in September, after the second week of the payroll debacle, and has now had to do so again.
He has had no response, and said he expects his school to be repaid thousands of dollars spent sorting out the payroll mess "when pigs fly".
The payroll debacle has been time consuming and placed a huge amount of stress on many schools, say school heads. The only compensation the MoE has offered is "the legitimate cost" of staff to attend Novopay roadshows, two of which were held in Northland on Tuesday.
While the Government has assured schools the programme, owned by large Australasian human resources company Talent2, is being improved, the number of errors made in Kiwi teachers' pay in the last two weeks alone stands at 3227.
