This study examined the investigation of tender irregularities within the City of Tshwane Metropolitan Municipality (CoT) and employed semi-structured interviews with investigators attached to the CoT Group Audit and Risk (GAR) Division within the Protection Service to obtain data. A literature study relating to aspects of tender irregularities and the investigation of non-compliance was conducted. From the results of this research, it appears that participants do not optimally investigate the non-compliance of tender procedures by service providers to reduce tender irregularities within the CoT. However, it is apparent that participants experience challenges to efficiently investigate the non-compliance of tender procedures by service providers within the CoT to reduce tender irregularities. The study makes recommendations that could assist investigators at the CoT GAR Division to enhance their investigations of the non-compliance of tender procedures by service providers. / Criminology and Security Science / M.
