Marylands School which was operated by the Brothers Hospitallers of St. John of God, a Catholic religious order in Christchurch, was the centre of a number of sex abuse cases.
By 2006, the Australasian branch of the St John of God order had paid out $5.1 million to survivors who had been sexually abused at the school. A nonprofit trust, the Survivors of Sex Abuse Trust, worked with many of the victims. Over 120 complaints were made in regard to sexual and physical abuse alleged to have occurred at the school. Many of the offences were committed in the 1970s.
The head of the Brothers of St John of God, Brother Timothy Graham, said,
"I repeat my unreserved apology and that of the Brothers of St John of God to each and every victim of sexual abuse as well as profound sadness for the crimes that took place at Marylands all those years ago."
Brother Bernard Kevin McGrath received 21 guilty verdicts and pleaded guilty to one charge of sexually abusing boys. In 2009 TV One screened an episode of Real Crime: Beyond the Darklands in which clinical psychologist Nigel Latta talked to McGrath's victims and evaluated his motivations and likelihood to re-offend. In November 2012, 252 new charges were laid in New South Wales against McGrath alleging that he repeatedly raped, molested and abused dozens of young boys at church-run institutions in the Newcastle-Maitland diocese over several decades. McGrath, then aged 65 years, flew back to Christchurch from Sri Lanka on 29 November 2012 and was arrested on Friday 30 November to face proceedings to extradite him to Australia on the new charges. In late 2014 he was extradited to Australia and appeared in court on the charges contained in an 8000-page brief.
In 2008 Brother Roger Maloney, who also worked at Marylands School, was found guilty of seven sex abuse charges and was acquitted of a further 16. After being extradited from Australia, he was jailed for three years for committing sex offences. He unsuccessfully appealed against the length of the sentence. After serving 13 months of a 33-month sentence he was accepted back into the Australian branch of the Order of St John of God.
