The Foundation said it was 'seeking expressions of interest from agencies that can help take the profile of the Prize to a new level as it focuses on regional publicity and outreach activities, and building the Prize's brand'.
This pitch process is at an early stage.
Established in 1987, the Commonwealth Writers' Prize rewards new Commonwealth fiction and looks to ensure that 'works of merit' reach a wider audience outside their country of origin.
It covers the Commonwealth regions of Africa, the Caribbean and Canada, Europe and South Asia and South-East Asia and Pacific.
'We are always looking to inject fresh energy into the Commonwealth Writers' Prize,' said Commonwealth Writers' Prize manager Jen Sobol. 'There is tremendous potential to use public relations to help achieve what the Prize is all about - bringing great books from all over the world to new audiences.'
