The local arm of ANZ will remain with TBWA Auckland.
This news comes only a few weeks after the Herald reported that Special Group's Auckland office had claimed the Kiwibank account in this market.
Interestingly, Special Group's Auckland office also holds the account of Australian telco Optus - an indication of the strong reputation the agency enjoys across the ditch.
Special Group has outlined bold global intentions, launching in the US market last year despite the impact of Covid-19.
The US office, based in Los Angeles, currently counts Uber Eats among its list of clients.
The Herald has approached both ANZ and Special Group for comment.
