Public sector audit: new public management influences and eco-system driven reforms

PurposeNew public management (NPM) has transformed the public sector auditing context, although in quite different ways. Further, investigations into NPM's impact on public sector auditors and audit institutions have been largely unconnected, with the exception of the critical examination of performance audits. We investigate the question of how public sector auditors' roles and activities have changed as a result of NPM and later reforms.Design/methodology/approachWe examine and synthesise public sector audit research examining reforms since the year 2000. The research presented considers changes to external and internal public sector audits as well as the development of public sector audit institutions - known as supreme audit institutions (SAIs).FindingsConsiderable changes have occurred. Many were influenced by NPM, but others have evolved from the eco-system of accounting, auditing and public sector management. External auditors have responded to an increase in demand for accountability. Additional management and governance techniques have been introduced from the private sector, such as internal auditing and audit committees. NPM has also led to conflicting trends, particularly when governments introduced competition to public sector auditing by contracting out but then chose to centralise to improve accountability. There is also greater international influence now through bodies like the International Organisation of Supreme Audit Institutions (INTOSAI) and similar regional bodies.Originality/valueNPM reforms and the eco-system have impacted public sector auditing. Sustainability reporting is emerging as an area requiring more auditing attention; auditors also need to continue to develop better ways to communicate with citizens. Further, research into auditing in non-Western nations and emerging technologies is also required, especially where it provides learnings around more valuable audit practices. Empirical evidence is required of the strengths and weaknesses of SAIs' structural variety.
