This study investigated the factors confronting the effective implementation of humanitarian services by non- governmental organizations (NGOs) in IDP camps in North-East Nigeria. Using the discourse analysis to analyze qualitative data collected through participant observation, informal discussion and interview from 42 officials selected through snow-ball sampling techniques in NEMA recognized and approved camps. Among other findings, it was revealed that in terms of jurisdictions, some of the NGOs are limited in operation, while others are versatile but limited in service delivery; also, policy and guiding principles of the various NGOs has created duplication of the nature of service and role conflict. It was recommended majorly that there is need for the government of Nigeria to take the center stage in the management of programmes and activities of humanitarian services in-line with international best practices. This will help to create a central coordination and administration of long-term programmes for the IDPs.
