The Omnicom-owned agency picked up the brief following a competitive pitch process against undisclosed agencies.
Apple's above-the-line relationship with sister Omnicom agency TBWA\London is not thought to be affected by the review.
However, the move throws into question the future of a full-service specialist agency, called Media Arts Labs, that TBWA\London had been planning to service the Apple account. The agency was due to be based at Tequila\London's offices.
Last month, Apple approached agencies regarding a large scale email marketing brief. It is not known whether the work will now be handled by WWAV.
Calls to Apple were not returned and WWAV declined to comment on the appointment.
