Mary is a Young Samoan Professional based in Wellington, New Zealand and holds a Master of Arts with Honours in Criminology from the University of Auckland, where her research explored Restorative justice as a culturally appropriate approach for dealing with violent offending in New Zealand. Mary currently leads 350 Pacific Climate Warriors (PCW) in Wellington New Zealand which is a dynamic network of youth-led, grassroots Climate Activists from across the Pacific, advocating and working with and for communities on the front-lines of climate change. Wellington was the only city in NZ to co-host the recent climate strikes with an Indigenous climate group which saw the Pacific Climate Warriors lead a 40,000 strong Wellington Climate March to the steps of parliament. As an advocate for educational equity and climate justice, Mary believes a restorative justice approach and Indigenous perspectives must  underpin and central to the Climate Conversation. She advocates that young Indigenous people have the energy, passion, and the courage to be the innovative and compassionate thinkers that will change the world and solve climate change.

Mary is currently the One Young World (OYW) Coordinating Ambassador for the Pacific region, and sits on the Commonwealth Youth Council, Inclusion and Engagement Committee as well as the International Taskforce for the Commonwealth Youth Forum in 2020.
