The review also found that the council's rules were unclear and "confused" when it came to dealing with individual teachers' conduct.
Teachers Council director Peter Lind said that in the absence of clear legislative guidelines for naming teachers who had been disciplined, the council gave blanket suppression to any offenders.
He felt that the Education Act should be amended so that teachers had similar legal protection to doctors.
"If we had those, then it would answer some of the calls about whether or not these cases should be heard in public."
Secondary Principals' Association president Tom Parsons echoed the need for clear rules which made teachers accountable but also protected innocent parties.
"There are not many teachers who support anything that's happened previously with the confidentiality and ... no justice being seen to be done."
The report found that child safety in schools was the top priority. Education Minister Hekia Parata has released a discussion paper with recommendations for reform.
Teacher conduct
The council's complaints process was considered too closed to the public, slow and cumbersome, and had led to too few de-registrations. The review recommended that the council develop a code of conduct and that the law be changed to allow serious offences to be referred immediately to the Disciplinary Tribunal.
Registration
The council did not give the same emphasis on developing professional practice as the legal or medical professions. The committee recommended that membership of the Teachers Council should be separate from the issuing of a practising certificate, and that teachers should have to renew their certificates more regularly than every three years.
Teacher competence
The committee recommended raising the bar for the profession by requiring teachers to hold a post-graduate qualification.
Accountability
The council needed to be more accountable to the public with regard to teaching standards, competence and conduct. The committee said it should have to produce an annual report, and that the minister should have power to demand information or an audit.
Governance
The committee recommended a smaller eight-person council board with all members appointed by the Education Minister.
