Ms Huygens researches how dominant and coloniser groups may participate in liberatory social change. She uses historical material, discursive analysis of accounts of change and participatory theorising among her fellow activist educators. Emeritus Professor Ranginui Walker, University of Auckland, says "Ms Huygens thesis on the Maori struggle for recognition of their tino rangatiratanga (self determination) under the Treaty of Waitangi, and the efforts of Pakeha treaty educators to help Maori bring about transforming action towards that goal is a sound and tightly written piece of work. She did admirable field work visiting treaty networking groups in town and city centres exchanging ideas, seeking common understandings. She brings to the table new theorising about social transformation". Professor Darlyne Bailey, University of Minnesota, says "Processes of Pakeha change in response to the Treaty of Waitangi is an evidence-based story that must be broadly shared. It begins with a very personal accounting to arrive at a series of recommendations for creating both a theory and a practice for Pakeha change with implications for future research and work across the world".
