Miranda says about her role as an Ambassador for Women’s Refuge: “The statistics for violence against women and children in Aotearoa/New Zealand are distressing. We all need to work together to make our communities safer places to live, learn and work. I am proud to be connected with Women’s Refuge! Let’s support our mothers, children and families”

“The welfare of women and children has been close to my heart for many years, particularly after delivering some of the horror stories in our news bulletins. The science of brain development tells us how damaging exposure to domestic violence is for the brains of young children. It also tells us that being surrounded by violence is just as bad as actually being hit. I wholeheartedly support the work of Women’s Refuge to provide services that help women and children escape violence in their lives.”
