On a charge of serious misconduct, the woman was censured and conditions were placed on her practising certificate for five years that she must disclose the decision to all future employers who require a practising certificate and tell the council that she had done so.
In another decision, a high school teacher had his registration cancelled after threatening to kill his Year 11 science students, saying he hoped to meet them down a dark alley.
School authorities learned last year of the threats after a parent complained in May that the man had "threatened to smash the children's heads in" and said she had concerns about his behaviour in the past.
The teacher admitted in a meeting with the acting principal that he had "lost the plot" verbally with the Year 11 students but that he did not "throttle the clowns".
Separately, four other students complained that the teacher was so upset with a group of latecomers to the class that he called the entire group "motherf*****s", and stood in front of a group of girls and said, "I hope I meet youse [sic] down a dark alleyway so I can kill the lot of youse, make youse bleed and cry for help."
Students said they felt uncomfortable and scared.
The board of trustees of the school, which was not named in the decision, determined the man's behaviour amounted to serious misconduct and he resigned in June last year.
The Teachers Council has cancelled his registration. APNZ
