The Associated British Foods-owned savoury cracker brand plans to shortlist seven agencies with direct and digital capabilities, with a view to holding credentials meetings in April.
It plans to appoint four agencies to its roster and will then brief them on a project-by-project basis to produce a variety of eCRM, digital and promotional campaigns.
It is not known whether Ryvita's incumbent below-the-line agency, Beechwood, will compete for a place on the roster.
The review does not affect the agencies Mortimer Whittaker O'Sullivan Advertising, or ZenithOptimedia, which currently handle the cracker brand's advertising and media planning and buying accounts respectively.
The news comes not long after Ryvita appointed Nigel Nelms, the former Johnson & Johnson marketing director, to an equivalent role in November last year, replacing Rob Murray.
