Nairobi Governor Johnson Sakaja has removed Chief Officer Geoffrey Mosiria from the Citizen Engagement and Customer Service docket in a county administration reshuffle that assigns the responsibilities to another officer in an acting capacity.
The changes, announced on Wednesday, October 21, 2026, were contained in a letter from the Office of the Governor signed by County Secretary and Head of County Public Service Machel Waikenda.
Under the new arrangement, Zipporah Njeri Mwangi will take up the additional acting role of Public Participation, Citizen Engagement and Customer Service while retaining her portfolio as Chief Officer for City Culture, Arts and Tourism.
The notice does not mention Mosiria by name or explain why the responsibilities have been reassigned. It also does not explicitly state whether he has been dismissed from his position as a county chief officer.
The changes take effect immediately.
Sakaja names acting officers
The reshuffle extends beyond the Citizen Engagement and Customer Service department, with two other county officers receiving additional responsibilities.
Eng. Samwel Njogu has been assigned the acting Mobility docket, while Godfrey Akumali, who heads Housing and Urban Renewal, will additionally serve as acting chief officer for Lands.
The latest changes place the Citizen Engagement and Customer Service docket under Mwangi’s leadership in an acting capacity, ending Mosiria’s previous assignment to the department.
Mosiria’s City Hall Journey
Mosiria was reassigned to Citizen Engagement and Customer Service in November 2025 after serving as chief officer for Health and later Environment.
He gained public visibility during his tenure in the Environment department through enforcement operations targeting noise pollution and illegal dumping in Nairobi.
His time at City Hall has also featured public disagreements over his responsibilities and working relationship with other county officials.
While serving in the Health department, Mosiria previously raised concerns about the removal of his accounting-officer powers and his access to the governor.
The latest reshuffle does not provide an official explanation for the change affecting his docket, leaving his next assignment unclear.
