Bernard McGrath was born in Christchurch and entered the Australasian Catholic Order of St John of God as an eighteen year-old. In Sydney he underwent religious training and qualified as a teacher. In 1974 Brother McGrath returned to New Zealand to teach at the Order’s school for special needs boys, Marylands School, in Christchurch. However soon after he began working at Marylands, he started sexually abusing the boys in his care. Clinical Psychologist Nigel Latta examines why Brother Bernard McGrath started abusing children, how he managed to silence his victims for, and how he continued to abuse for over two decades.
