Nairobi Governor Johnson Sakaja has unveiled a restructuring of Nairobi City County’s leadership, reassigning multiple County Chief Officers (CCOs) in a bid to enhance service delivery across various departments.
In a directive issued on April 24, 2026, the governor confirmed that the modifications are effective immediately, citing the necessity to improve efficiency in critical areas such as lands, healthcare, and infrastructure.
“Pursuant to Section 45(5) of the County Government Act 2012, the following County Chief Officers have been reassigned,” part of the official communication stated.
Among the significant adjustments, Dr Machel Waikenda, who previously managed Mobility and also served in an acting capacity in ICT Infrastructure, has been transferred to the Lands portfolio while maintaining temporary responsibilities in mobility.
Cecilia Koigu, who has been operating in the Lands department, has now been reassigned to supervise ICT Infrastructure. Koigu was among the chief officers appointed during Sakaja’s initial selections in 2022 and has played a pivotal role in the lands sector before this reorganization.
Other modifications include Eng. Bob Arriemba, who assumes duties in the Works department, while Dr Irene Muchoki shifts from Medical Services to Gender and Inclusivity. Mariam Dubow Dahir has been relocated from Gender and Inclusivity to Medical Services.
The governor indicated that the reshuffle forms part of continuous efforts to optimize performance within the county government by matching expertise with priority areas.
“These changes aim to streamline operations and enhance service delivery across essential sectors,” the statement emphasized.
The reorganization occurs as the county government faces increasing demands to improve efficiency and resolve challenges confronting residents, particularly in urban planning, healthcare, and infrastructure development.
With the immediate enforcement of the changes, the affected officers are anticipated to commence their new positions without delay as the county endeavors to increase productivity and responsiveness in public service.
