Natasha Tassell-Matamua, Ph.D.

Natasha Tassell-Matamua, PhD, is the Director of the Center for Indigenous Psychologies and Associate Professor at the School of Psychology, Massey University, New Zealand.  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 has a personal interest in Buddhism, having informally studied it as a way of being for more than 25 years. More recently, she has become interested in psychedelics as transformative experiences.  She enjoys gardening, hiking, growing mushrooms, 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.

She began studying near-death experiences (NDEs) in 2010 after completing her PhD. Since then, she has extended her research to encompass other non-ordinary experiences of consciousness, most recently including end-of-life experiences (ELEs) and terminal lucidity (TL). She also incorporates Indigenous knowledge into much of her work, particularly regarding methods and methodologies. Her research now focuses mainly on the interface between non-ordinary experiences of consciousness, spirituality, and Indigenous psychologies. To a lesser extent, her research also explores how these topics relate to ecopsychology. She is interested in extending her research of non-ordinary states to incorporate psychedelic-facilitated experiences and how these may be similar to or differ from near-death experiences in phenomenology and aftereffects.

In 2023 she became an Associate Editor of EXPLORE: The Journal of Science and Healing.
