Te Papa Tongarewa, the Museum of New Zealand, is a cultural institution located in Aotearoa New Zealand. The museum’s foundational principle of biculturalism appears increasingly inadequate for addressing the fundamental injustices associated with settler/invader colonialism and can be seen as a barrier to achieving a “collective future.” This article argues that Te Papa must discard biculturalism insofar as it does not provide for tino rangatiratanga (self-determination) or mana motuhake (Indigenous sovereignty). Currently, Te Papa promotes Indigenous cultural inclusion and the celebration of Te Ao Māori (The Māori World) within a settler/invader-defined national identity and cultural memory. In the future, a decolonial and tikanga-based (Māori legal and customary practices and system) approach should be implemented at Te Papa.
