A repeat sex offender who preyed on men with mental disabilities was able to offend again - despite being monitored by authorities.
Now, the Department of Corrections has been granted a second extended supervision order to confine Suafai Aima'asu to his home and only allow him to leave with an approved person.
In 2007, Aima'asu came across a man with a mental disability who was out getting milk. He led the man to a sleep-out behind a nearby empty house and forced him to perform a sex act.
He then went with the man to his home at a facility for adults with mental disabilities and helped himself to the man's CDs.
He pleaded guilty to a charge of exploitative sexual connection and theft, and District Court Judge Anna Johns sentenced Aima'asu to two-and-a-half years in prison.
When he was let out of prison in 2012, he was subjected to a 10-year extended supervision order.
Despite that, one year later Aima'asu was back in court, before Judge Gus Andre-Wiltens, after pleading guilty to another charge of sexual exploitation of a person with what was described as a significant impairment.
Aima'asu had talked his way into the home of the man and sexually abused him, before taking his CDs. Judge Andre-Wiltens noted Aima'asu remained at a high risk of re-offending.
Now, Corrections has been granted a second 10-year extended supervision order.
Corrections Department northern operations director Lynette Cave said Aima'asu must comply with special conditions that include 24-hour, seven-days-a-week residential restrictions. He can only go out if he is accompanied by an approved person.
He is also not allowed to be anywhere near people with disabilities.
In granting the extended supervision order, Justice Fogarty in the High Court in Auckland cited mental health assessments that found, despite treatment, Aima'asu still presented a high risk to the public.
Corrections staff have notified Aima'asu's community of his release.
Aima'asu also has convictions in the '90s for sex offending against boys.
