The Public Affairs Department (PAD) was established in June 2022 by the Director-General, Prof. Omotayo. Prior to its establishment, the National Institute operated the Advancement and Linkages Unit as well as the Protocol Unit. However, the creation of PAD as a department brought together the Advancement and Linkages and Protocol Units, in addition to three other units, namely: Public Relations, Media Relations, and the Multimedia Unit. Following this convergence, each of the five units was headed by a Unit Head with clearly defined responsibilities, operating under the supervision and coordination of the Head of the Department.
