Career
Maniwavie links threats to mangroves to climate change and the maintenance of Papua New Guinea's culture, saying:"Our greatest challenge in the Pacific is climate change. If we do not use our mangroves wisely, we will have no defence against climate change impacts, and we will end up losing our way of life and our identities."Maniwavie first worked in mangrove conservation as a volunteer at Motupore Island Research Centre. She attended the University of Papua New Guinea, studying general biology and marine biology. After university, she worked for the Wildlife Conservation Society, running community trainings on mangrove restoration.

In 2014, Maniwavie received the IBMM Young Achiever's Westpac Outstanding Women Award for her contributions to mangrove conservation.
