The study was conducted at Registrar of Political Parties office in Dar es Salaam. The researcher used interview, distributed questionnaires to collect the primary data, and analyzed the available secondary data. Data collected by the researcher were both qualitative and quantitative. The study adopted purposive sampling procedures as it intended to get opinions from User department, PMU, Finance department, ICT department, and Tender Board members and Audit department. The researcher generally found that there were a number of challenges facing the Registrar of political parties in implementation of the Act 2004. The challenges were; influence in the Procurement Process, interference by top management due to conflict of interest, lack of Training on Public Procurement Act, lack of accommodation of the requirements of the law by the organization structure, uncertainty in the availability of funds which affects the planning of the procurements and lack of cooperation from the user departments. Basing on the observations of the study, the researcher recommends the following:The management of the Registrar of Political Parties should take procurement as the priority area and ensure all procurements under their entity are compliant to the requirements of the Act. The government should take disciplinary measures to the managers who are reluctant in enforcing implementation of the law. The PPRA the regulatory authority, is advised to assess that PEs whose structures are not accommodating the requirements of the PPA, 2004 and forward recommendations to the lawmakers. PPRA in collaboration with RPP has to ensure vigorous efforts are taken to train procurement experts in the requirement of the procurement laws and increase their exposures on such requirements.
