... and particularly:
The interim period of Internal Self-government, did not witness any major constitutional changes. The constitutional provisions finalized in February, 1963 remained virtually the same. At midnight on December 11, 1963, Kenya regained Independence from the United Kingdom. Kenya remained a dominion within the British Commonwealth, with a Governor-General representing Her Majesty locally and a Government headed by a Prime Minister. Mzee Jomo Kenyatta, leader of the majority party in Parliament, became the first Prime Minister, heading a cabinet of fifteen Ministers and thirteen Parliamentary Secretaries. The late Ronald Gideon Ngala, leader of K.A.D.U. and Mr . Paul Joseph Ngei, leader of A. P. P. formed a Coalition Opposition under leadership of the former.
The composition to the Legislature and the framework of the Government at Independence remained in place until the first anniversary. Arising from close negotiations between the Government and the Opposition, a merger of all the parties represented in the House, under the Kenya African National Union - K.A.N.U. and under the leadership of Mzee Jomo Kenyatta was concluded and took effect on December 12, 1964, with the voluntary dissolution of the Kenya African Democratic Union - K.A.D.U. and the African Peoples Party - A.P.P. This merger meant an unanticipated de facto one party status. On December 12, 1964, Kenya declared herself a Sovereign Republic within the Commonwealth. Mzee Kenyatta become the first President, heading a Cabinet of eighteen Ministers. December 12, has since been celebrated as Jamhuri Day. The first Vice President, Mr. Jaramogi Oginga Odinga, resigned on April 14, 1966 and immediately formed an opposition party, the Kenya Peoples’ Union - K.P.U. This reintroduced a dejure multi-party status.

They called themselves a republic in their 1963 constitution, as per http://www.constitutionnet.org/en/vl/constituion-kenya
The key point is NOT the precise and correct terminology for Kenya’s form of government in August of 1964 but whether similar documents known to be authentic issued at the time from the same source used the same form.
