In a statement, the DOI said the new administration will be introducing a new structure in the secretariat of the Office of the Prime Minister and the ministries.
The secretariat of the Prime Minister will be headed by a chief of staff, Keith Schembri, who headed Labour's electoral campaign.
The DOI said that Mr Schembri, 37, will give the government system a new dimension because of his business background.
"His achievements, leadership qualities and creativity, along with his knowledge on the needs of investors should help the government understand the needs of the people who can create jobs in the country," the statement said.
He will give up his business directorates and posts while serving in the administration. (Mr Schembri is the owner of the Kasco Group).
Former journalist Kurt Farrugia, 31, the PL's head of communications, will become the head of government communications.
