The Principal of one of New Zealand's top schools has slammed New Zealand's education system - saying it's heading towards rock bottom.

Auckland Grammar head Tim O'Connor says the profession isn’t as valued as it once was.

He told the Herald's Leaders Getting Coffee podcast that's evident by people not wanting to enter the profession and the fact that schools can’t easily access specialist teachers.

He says the system's not doing itself any favours by lowering standards within the curriculum.

Tim O'Connor joined Simon Barnett & James Daniels to discuss his thoughts.
