Minister in charge of Novopay Steven Joyce says he understands the frustration of secondary teachers who say they will pursue legal action over the Novopay payroll system.
Post Primary Teachers Association president Angela Roberts announced today the union would take legal action on behalf of some of its 18,000 members.
PPTA could not confirm who the action would be taken against - the Education Ministry, Australian company Talent2, or both.
Ms Roberts said teachers who were members of the PPTA were losing patience with ongoing problems with the payroll system and sympathy from Mr Joyce had not resolved their frustrations.
"Continued Novopay errors mean schools, students, principals and administration staff are at the end of their tether," said Mrs Roberts.
