Upon his return to Tanzania in 1954, he joined his family’s sisal plantation business and eventually managed the plantations for both his and his wife’s family. His passion for flying prompted him to buy an aeroplane which he used to fly to and from Dar es Salaam when he had to purchase supplies for the plantations. He managed the plantations, developed and doubled the production. He was an active member of the Tanganyika Sisal Growers’ Association, eventually becoming member of the Executive Committee and Chairman of the Central Line Zone. Prior to Independence Dinos Samaras joined TANU, was elected a member of the Legislative Council and represented the Morogoro constituency. He was later re-elected as a Member of the National Assembly and after Independence a member of Parliament.
He continued to manage the plantations until Independence and the eventual nationalization of the plantations in 1967.
Two years later, in July 1969, Tanzanian Air Services Ltd – TANZANAIR was launched. In 1971 the Government allocated him a piece of land adjacent to the old international terminal and he was instructed to build a hangar for the Company. In 1977 the Government encouraged the Company to build its Engineering facility. Until then all aircraft had to fly to Nairobi for maintenance.
Dinos Samaras also had the honour of being appointed to Consul General of Greece in Tanzania. He served for a period of 15 years during which time numerous Tanzanians were granted scholarships to study in Greece and find employment in Greece’s merchant marine fleet.
Today TANZANAIR employs over 70 personnel in the Operations, Engineering and Administration departments.
