ANZ's saturation sponsorship of Valerie Adams' gold medal ceremony will be salt in the wounds of a rival bank and fellow Olympic sponsor, a marketing expert says.
Wednesday's ceremony at the Cloud was paid for by ANZ, which was the official insurance provider for the New Zealand Olympic team.
John Guthrie, senior lecturer in marketing at Otago University, said the high-profile event would be galling for ASB - which paid top dollar to be the Olympic team's "official bank".
"What is a brand? You'd have to think that with ANZ, do we know that as an insurance provider? I don't think so.
"I don't know the level of contribution that these banks make, but it looked to me like it was flying under the radar."
