Call centres set up to deal with teachers' payroll problems have taken more than 800 calls after the first pay round of the school year, with hundreds of teachers expected to be underpaid or not paid at all.
Ministry of Education officials have manually paid 86 teachers this week after "discrepancies" in their pay packets, but the number of total errors was expected to be in the hundreds.
A ministry call centre received 228 calls on Waitangi Day and a further 102 calls and 197 emails yesterday from teachers, principals and payroll administrators.
Payroll company Talent2's call centre had also taken more than 500 calls since the pay round this week.
Education Minister Hekia Parata said it was expected that the start-of-year payments would be difficult.
