The incumbent Maxus will defend the business in a pitch against an undisclosed line up of agencies.
"OCBC Bank confirms that we have called for a fresh pitch for our media buying account. This exercise will enable us to assess all the accomplished media buying agencies in the market and select the right one to support us as we explore fresh and creative media buys for our advertising campaigns," said Koh Ching Ching, head, group corporate communications, OCBC Bank.
"We have been working with Maxus since 2000 and there is a good chance that they will continue to be our agency if their strategy for our business turns out to be the best," she added.
An appointment is expected by July.
