The history of citizenship education in New Zealand has entailed several key moments that have been subject to contested historical, social, political and economic forces. While there has never been a stand-alone citizenship education curriculum in New Zealand, the social studies curricula remain the primary vehicle for citizenship education delivery since its origins in 1944. This chapter examines the development of citizenship education, through New Zealand's social studies curricula, as an 'education ensemble' in which five historical moments of "politics, policy and practice" (Dale, 2017) emerged. Examining these moments against a critical theoretical lens, this chapter considers the possibility such moments held for the development of more critical and active citizens. The authors analyse the more recent emphasis on social inquiry and social action as two further moments of possibility for enhancing critical and active citizenship. This analysis attests to the potential for critical change through curriculum reform, but also, in contrast, the potential for an enduring minimal, content-heavy, and neoliberal approach to learning citizenship in the absence of seizing a curriculum moment. In doing so, the chapter contributes to wider debates about how citizenship curricula is positioned within an ensemble of competing political agendas, practitioner influences, and policy frameworks.
