The pair is the first creative hiring made by Wunderman’s chief creative officer, Matt Batten, who joined from Wunderman Australia in December.
Wagner and Fastnedge have previously worked at M&C Saatchi Auckland, where they worked on accounts including Viagra and Stella Artois. They will now work on clients including Microsoft.
Batten has also moved Ben Cobley from the WPP agency’s strategy department into its creative department. Cobley will work alongside teams in the production of social content and integration with broader creative campaigns.
Batten said: "We’ve better aligned the talent to get the foundation right, refitted the creative department into their own collective space and then brought in fantastic new talent to build a better department that focuses on inspiring creativity."
