The idea of wellbeing is increasingly prevalent in global policy contexts. Yet, as the chapters in this collection demonstrate, any understanding of wellbeing is contextual: what wellbeing is depends on where and how we listen and speak, the concepts at our disposal, the humans and nonhumans with whom we engage, and the focus of their, and our, aspirations. Many of the chapters in this collection reflect the context of Aotearoa New Zealand, which, in 2019, introduced a wellbeing approach to public policy that attracted the attention of global policy makers and other stakeholders. In this collection, commentators both from within and beyond Aotearoa take an expansive stance in discussing the concept of wellbeing and its myriad possibilities. The authors speak from an array of disciplines to present and critique ideas about how wellbeing can be understood and pursued across the life course.
