Changing the boundaries of public sector auditing

Purpose- This paper aims at reflecting on the changing boundaries of public sector auditing. In particular the paper focusses on the opportunities and challenges for performance auditing, for sustainable development auditing and digitalised public sector auditing.Design/methodology/approach- Building from the papers in this special issue, the authors draw on the literature on current development of public sector auditing (such as public sector auditing performance auditing, sustainable development auditing and digitalised public sector auditing) and propose a future research agenda.Findings- The "changing boundaries" of public sector auditing may influence the difficulty for public sector organisations to manage the uncertainties and risks not only associated to corruption but also the public governance development (collaborative, digital and emergency governance). The authors speculate on the role that the "changing boundaries" of public sector auditing can play.Originality/value- The paper contributes by setting new research avenues for future studies on public sector auditing in a post-new public management context.
