The paper cited TPA Corporate and Communications Manager Franklin Mziray as saying that the new ports would be at Bagamoyo, Mwambani and Tanga.
Currently, the Tanzanian port of Dar Es Salaam is the main export-import port for a number of land-locked areas, including mineral-rich Zambia and Congo's Katanga province.
The newspaper also said TPA has invested in an Inland Container Depot, located about 40 km west of the harbour, to reduce container congestion at Dar Es Salaam port.
