WELLINGTON, April 6 - The teacher faced seven charges from three complainants in a trial at Auckland District Court last month.
Name suppression was in place for everyone involved.
The teacher, who taught at an Auckland intermediate school, was alleged to have indecently touched the complainants between May 2016 and March 2017 when they were about 11 years old, according to Stuff.
Two of the complainants disclosed the alleged offending to another teacher on March 23, 2017.
The school undertook an official investigation and the police became involved.
However, the pupils admitted under cross-examination in court they fabricated the story because the teacher yelled at them in class.
A boy, who initially claimed he witnessed the indecent acts - which included alleged stroking of the girls' hair and grabbing their breasts - admitted there had been a plan to make up stories after the teacher had told them off during class for misbehaving and being disrespectful.
Despite the admissions - after which the jury at the recent six-day trial took less than an hour to find him not guilty - the teacher has lost his job and told Stuff a 40-year career, including 27 at that school, was in ruins.
He admitted that in March last year there was a standoff in the classroom after pupils began painting their arms and hands black, and he lost his temper at them.
Police said it was disappointing when untruthful accusations were made but they were obligated to act when children said they were assaulted.
