Arapera’s main research interests are concerned with the revitalisation of te reo Māori. Her doctoral study addresses Māori views on whether te reo is a language for all New Zealanders. That work is particularly concerned with the relationship between language and identity and how it underpins the responses from the Māori community as to whether they can support non-Māori to learn their language. She has been involved in several recent research studies in Māori communities, and is well-versed in appropriate modes of working within that paradigm.
