A Whangarei man whose sister was killed in a highly public case of domestic violence will today become an ambassador for anti-violence group White Ribbon.
John McGrath will be made a White Ribbon Ambassador in a ceremony at Whangarei Boys' High School.
Phillip Andre Mahanga, 33, was sentenced to three years' jail in July last year for the manslaughter of 34-year-old mother of two, Patricia Ann McGrath, known affectionately as Wowo.
The couple had been in a relationship for 14 months but her family had never met Mahanga.
After his sister's death Mr McGrath became involved in the anti-violence movement, including leading a march through Whangarei in January last year just days after his sister died on January 8.
