The Port Authority (PA) Division of MPDC assumes custody of the Landlord function of the port. Therefore there is a strong focus on the Regulatory and Legislative areas of Port Maputo. Port authority is also responsible for the maintenance and development of Port Infrastructure. This includes quays, roads, warehouses and channel areas.

The very important functions of Health, Safety, Environment & Security also fall under Port Authority. The Marine Department falls under PA, so all Shipping movements, Pilotage & Towage are part of MPDC Port Authority functions.
