All COI media buying roster agencies have been put on notice in preparation for the review.
Previously COI has split its six media-buying contracts across five agencies by medium. TV and cinema is handled by Carat, press by Mediacom, digital by i-Level, radio by Starcom and outdoor by Posterscope.
Digital agency i-Level's will be the only agency unable to pitch for the entire business.
The pitch follows an operational review of COI media buying by former Radio Advertising Bureau chief executive Douglas McArthur.
