This follows NRMA's appointment of MediaCom to handle its media buying services last December.
NRMA Motoring & Services provides its members roadside assistance as well as travel and lifestyle benefits, products and services. It is Australia's largest member organisation.
Commenting on the win, Toby Jenner, CEO of MediaCom said extending the agency's partnership with NRMA was a big opportunity, as "retention and growth of our existing client partnerships is critical across all areas of business".
The win makes NRMA one of MediaCom's search business' largest clients. The appointment is effective immediately.
