President William Ruto has been an enthusiastic backer of the mission and said this month that the deployment would begin within weeks.
“The departure is this week on Tuesday,” an interior ministry official said on condition of anonymity.
“Preparations are set for the team to depart for Haiti on Tuesday. We already have two advance teams that left — one last week and another one yesterday,” a senior police official said.
A United Nations Security Council resolution in October approved the mission but a Kenyan court in January delayed the deployment.
It said the Kenyan government had no authority to send police officers abroad without a prior agreement.
The government secured that agreement on March 1 but Ekuru Aukot’s Thirdway Alliance has filed a fresh lawsuit to try to block it.
Aside from Kenya, other countries that have expressed willingness to join the mission include Benin, the Bahamas, Bangladesh, Barbados and Chad.
The United States is providing funding and logistical support, but not boots on the ground in Haiti, the poorest country in the Americas.
