"From a Hawke's Bay perspective, there has been a large turnover of principals in the last two to three years so you do have new people coming into established schools that may have different visions.
"When they step into the school community, they are seeing the school through new eyes and they are seeing things they don't think are right," he said.
During 2014, four teachers were reported for relationship and employment matters, four were reported for incompetence, two were reported for aggressive behaviour, one was reported for inappropriate behaviour while three were reported for violence. These reports did not result in convictions.
However, a further six teachers were criminally convicted for drugs and alcohol while one teacher was convicted for driving offences.
In 2013, two teachers were reported for relationship and employment matters while five were reported for incompetence.
A further six teachers were criminally convicted for drugs and alcohol, two were convicted for dishonesty/fraud, one was convicted for violence while one teacher was convicted for driving offences.
Mr Williams said he was not concerned about the overall quality of teachers but felt systems could be improved.
"With our staff everyone is police vetted and everyone has to go through the appraisal system each year, and those systems are robust, everyone is now ticking boxes, dotting i's and crossing t's," he said.
"Teachers are however, spending more time doing paperwork for paperwork's sake to meet all these criteria instead of the core business of being a frontrunner, working with kids. If anything, is the system broken?"
Teachers Council acting director, Rob McIntosh, said the figures indicated, "a well-informed profession". He said reports increased after nationwide workshops in 2013 and 2014 to ensure teachers and principals were fully aware of their responsibilities.
Mr McIntosh said changes to council rules has also resulted in an increase in the reporting of incidents.
"In 2014, a change was made to Council rules which requires all hearings of the Disciplinary Tribunal to be held in public, unless there is a compelling reason not to do so (e.g. vulnerable witnesses).
"The rule change also removed automatic name suppression for teachers in written Disciplinary Tribunal decisions.
"This change means teachers, students and parents can be fully aware of sanctions imposed against a teacher - this acts as a deterrent, and an accountability measure."
"While cases of inappropriate conduct by teachers often attract media attention, it is important to remember that there are over 100,000 registered teachers in New Zealand, and only a tiny fraction of them have any conditions attached to their practice," he said. NZME
