A teenager who was repeatedly molested by his teacher is still haunted by the encounters decades later.

The former teacher, Kairau Ngahau, 76, was on Wednesday sentenced in Tauranga District Court to five years and nine months in jail on a representative charge of sodomy on a male under 16, and seven other charges of unlawful sexual connection on a male 12 to 16 and indecent assault on a male 12 to 16.

Judge Peter Rollo said Ngahau's actions had "grossly and irreparably damaged" the lives of his three victims.

Ngahau's first victim, "victim one", had her victim impact statement read out by Crown prosecutor Anna Pollett, telling how the abuse affected her life so much, she made the choice to begin surgically transitioning from male to female.


She grew up male with a "lovely family" and started at Mount Maunganui College in the 1970s and began studying under Ngahau. He had been teased at school but thought of himself as a sensitive boy who liked beautiful things, rather than gay.

Ngahau began "favouring" him, asking him to stay late. Raised to respect elders and not to question them, victim one told no one when the abuse began in a back room of a classroom, starting with kissing and fondling, then growing worse.

"He made me afraid to go to class . . . I can still vividly remember the scent of your aftershave, which I think was Old Spice."

The victim remembered how, when he tried to call for help, Ngahau covered his mouth with his hand.

He left school early, and the lack of further education has impacted his life ever since, Ms Pollett read.

"I have never forgotten those incidents. They have haunted me.

"I can see them in my mind's eye as vividly as the day they occurred.

"I thought about taking my own life after each incident."

The second victim was also abused at school, being touched on the genitals in class. Ngahau moved to another town.

The third victim also had his impact statement read out in court, talking of how he has had to work through the trauma of being abused, which meant he had to go on the sickness benefit. Victim three, unlike the other victims, was not a student at the school.

He came forward about the abuse after the charges relating to the other victims were made public.

Ngahau had pleaded guilty to all charges and, in court, sat in the corner of the dock with his head bowed, leaning on his wooden walking stick.

Lawyer Tony Balme spoke of Ngahau's medical conditions, holding up a bag the size of carry-on luggage full of Ngahau's medical supplies. "It's a heavy bag."

Mr Balme said since his offending had come to light, Ngahau had virtually locked himself in his house and "found it difficult to emerge". "He is intensely conscious of his place in the community and the shame he has brought on himself and the shame on others - his wife, his whanau, his iwi."

A kaumatua of a Kawhia marae spoke on Ngahau's behalf about how the family expected Ngahau to pay for his crimes, but would always support him.

Judge Rollo took Ngahau's early guilty pleas into account when sentencing, as well as his age and his health, but also acknowledged the substantial breaches of trust, the vulnerability of the victims, the repetition of the incidents, the long-lasting effects on the victims and the level of premeditation.

As the offences were historic, the judge had to sentence Ngahau according to the laws of the time.

After sentencing Ngahau to prison, Judge Rollo said there was little more that could be said.

"What you have done has been a terrible thing to young persons who were in your care."
