Former school rugby coach Alosio Taimo found guilty of sexually abusing boys

School rugby coach Alosio Taimo, previously known as a well-respected and senior community member, has been found guilty of 95 charges relating to sexual assault.

"This has been a long and harrowing trial," the judge said after the verdicts had been read out.

The prosecution provided details of several instances of sexual assault, and argued he gained victims' trust and then exploited them.

But defence lawyer Panama Le'au'anae argued Taimo was simply a mentor to the boys, and wanted them to excel.

"They all have an association with each other. These boys have got their heads together and have talked about... sexual abuse," he said.

Of all the charges, 24 of those related to sexual violation by unlawful sexual connection; 23 of indecent acts on a person under 16; 18 of committing an indecent act on a child under 12; 10 charges of indecent acts with a boy under 12; and 10 of indecency with a boy between 12 and 16.

Ten of the 18 complainants are related to Taimo's tenure at a school, and as a rugby coach. The remaining eight are older, with some allegations dating back to the 1980s.
