The actor left the Channel 4 soap in February after playing Sam 'OB' O'Brien for ten years.
However, he is currently back on set with Matt Littler, who plays his best friend Max Cunningham. They were named best screen partnership at Saturday's British Soap Awards.
He told the Press Association: "I'm actually back for a storyline, quite a short one with Matt. At the minute we're filming it.
"When I decided to leave I was asked to come back in a couple of months for this storyline that we're doing now so fingers crossed, wait and see."
Littler added: "Secret stories, so it's always been the plan from the start. Watch this space."
He admitted that he had missed working with his on-screen partner-in-crime, joking: "I ring Daz a lot from work crying. Just sobbing at lunch sat on my own in the car park in my car."
