President Uhuru Kenyatta has ordered all heads of procurement and accounting units in ministries, departments and state corporations to step aside.
The officials' were asked to do so immediately and their deputies to take over.
In a statement to newsrooms on Monday, Mwenda Njoka on behalf of the Government Spokesperson, said the officials are required to submit their personal information to the Head of Public Service by June 8.
In his statement, Head of Public Service Joseph Kinyua said the information includes certified copies of mobile money statements of the officers and their spouses for a period of six months and three-year income tax returns for they and their businesses for the last three years.
Those affected were also asked to detail club memberships and give information on social media accounts such as Twitter, Facebook and Instagram.
Kinyua further asked them to present lists of their liabilities such as school fees and school accounts, cumulative insurance policies, holidays, chattels, guarantees, mortgages, loans and guarantees.
The officers are to submit this information at Harambee House in Nairobi in line with the directive for their fresh vetting.
Kinyua said the officers may be summoned for oral interviews and that that additional information may be sought.
"Non-compliance with this directive will lead to disciplinary action. All information submitted will be treated with utmost confidentiality," he noted.
The move comes days after the President ordered the fresh vetting of public officers.
Uhuru has also undertaken a ruthless war on corruption and relies on confidential reports prepared by the National Intelligence Service.
The government will also rely heavily on the Auditor General’s reports, as indications of financial indiscipline, to root out graft and nail corrupt procurement chiefs, accounting officers, and unscrupulous traders.
Njoka noted: "Whereas the President is geared towards determining sustainability to hold public office in public trust and promote confidence in the public service, the same will be undertaken in a fair and objective manner, exercised with due care and regard to officers rights as enshrined in the Constitution."
