"Wetekia kia rere" is an expression in the Maori language that refers to "unleashing potential". This paper discusses questions of power relevant to challenges recently identified by government officials regarding learners' experiences of science education in New Zealand schools. We begin by summarising the Treaty relationship (Treaty of Waitangi, considered to be the country's founding document first signed in 1840) that informs the framing of New Zealand's science curriculum guidelines. Next we outline some official New Zealand education strategies along with several policy guidelines relevant to the aspirations of Maori communities for a transformative science curriculum. This is followed by a discussion of how the historical processes of ecological imperialism, environmental racism and institutional racism have combined to attenuate Maori experiences of science education. A review of international literature is then presented to support calls for the development of place-conscious approaches to science education which validate Maori knowledge and learning contexts and Maori initiatives to seek eco-justice. Finally, a case study of a Pa Wananga (Maori learning community) is provided to suggest potential solutions to some of the problems discussed previously.
