The Teachers' Disciplinary Tribunal has found there is insufficient evidence against a teacher accused of faking hundreds of sick days.
The tribunal was told the teacher was absent from her Auckland secondary school for an average of one day a week between 2008 and 2014.
The school said the woman was absent about 20 percent of the time and her students' pass rates dropped as a result.
The teacher said she suffered anxiety because of bullying at work. But the woman was charged with serious misconduct after the Education Council's impairment committee found the woman was not suffering from an impairment at the time of the absences, though she was unwell in 2014.
The tribunal said the teacher provided medical certificates for some of the days she was absent and the school had not challenged those.
It said it had heard no evidence to prove that the woman was well when she took sick days.
