Child, Youth and Family will be required to keep schools better informed of cases of child abuse they are investigating that involve a school's student.
And reports from teachers of suspected child abuse will be given higher priority under new processes announced yesterday.
Social Development Minister Paula Bennett said dedicated phone and email lines for reports from teachers would be set up from September 26 and concerns raised by teachers would be followed up swiftly.
If CYF wanted a school's help while investigating suspected abuse, wherever possible it would have to tell the school why it was asking and report back on progress.
In cases where teachers had reported abuse, CYF would report back to the school on its inquiries. Teachers would also be offered guidance on how to deal with problems of abuse.
