Peter Farrell, MD of Prima, says, "We like to think we impressed the client with our combination of strategic excellence and out-the-box creative thinking, but I also think that we are a good match. We are obsessive about branding, detail and production values - and so are they. We look forward to a long, mutually-beneficial relationship."
The agency has an awards tally since 2007 that includes eight Assegais (including the Nkosi and five Golds), two Echo Awards and three finalists, an Antalis Art of Design Award and three Loerie finalists.
