In Aotearoa New Zealand, liberative theology often assumes that postcolonial theology is the appropriate framework for addressing the colonization of the Indigenous Māori people. However, this paper challenges that assumption, arguing that Aotearoa New Zealand remains a settler colonial society where colonial structures persist, continuously dispossessing Māori and marginalizing their culture. The paper critically examines how postcolonial thought entered theological discourse through biblical studies in different contexts and contends that efforts to redefine postcolonial theology as a decolonial approach ultimately fall short. In response, this paper advocates for a Decolonial Settler Theology—one that fully acknowledges the ongoing realities of settler colonialism and seeks to theologically contribute to the decolonization of Aotearoa New Zealand. This argument has broader implications for other settler colonial contexts, including Canada, Australia, and South Africa.
