This research looked at the impact of port concessions on the ease of doing business in Nigerian ports, using Apapa and Tin Can Island Seaports as case study. The study's goal was to ascertain if the concessions at these ports had led to an improvement on the level of ease of doing business. The research was explained using the New Public Management Theory, which promotes the notion of developing a performance-oriented culture in a decentralised public sector. The survey research was used for the study, and this guided the use of a standardised questionnaire to gather information from the research participants. Even though they cannot be compared to international best practices, the ease of doing business at Nigerian ports has not been positively impacted as expected by the concession policy. As a result of this discovery, it was suggested, among others, that the government works with the concessionaires to increase infrastructure spending so that it is simple to enter and exit the port facilities. Additionally, steps should be taken to lessen the presence of MDAs and other security personnel at the ports.
