Natasha Tassell-Matamua, Ph.D.

Natasha Tassell-Matamua, PhD, is an independent researcher. Previously an associate professor in the School of Psychology at Massey University in Palmerston North, Aotearoa New Zealand, Dr Tassell-Matamua has more than two decades of research experience. Since 2009, she has focused specifically on near-death and other exceptional experiences of consciousness, pioneering the field of near-death studies in Aotearoa New Zealand. She established the Centre for Indigenous Psychologies at Massey University and was its founding Director until 2026.

She has lived in a variety of countries and cultures, including the Cook Islands, Singapore, Curacao, and Guernsey.  These experiences provide a useful foundation for reflecting on cultural diversity and its influences. She is especially interested in advancing understandings of cultural diversity in the area of exceptional experiences of consciousness. She has published extensively and presents both nationally and internationally on exceptional experiences and Indigenous knowledges.

She is also an associate editor of EXPLORE: The Journal of Science and Healing, and an associate editor for the journal Psychology of Consciousness: Theory,
Research and Practice. She enjoys gardening, hiking and being out in the natural environment. She is of Indigenous Māori, Cook Islands Māori, and Pākehā (NZ
European) descent; an ancestry that colors her experience of the world in varied ways.
