Ministry of Education hunting for source of leaks to RNZ

The Education Ministry has appointed a Kings Counsel to hunt the source of a series of leaks to RNZ. The ministry wrote to RNZ to share an internal message announcing the investigation by Michael Heron KC. It also invited RNZ to meet with Mr Heron - an invitation we've refused. This happened just hours after we revealed that a Public Service Commission push to stop leaks was itself leaked to RNZ. John Gerritsen is our education correspondent.
