A large magpie has had customers and staff in a west Auckland Countdown supermarket in a flap after it decided to spend this morning chilling out in the frozen food section.

Customer Helene Millar says her friend managed to get the bird out of the Te Atatu South store, amidst concerns staff may have been forced to bring its life to an untimely end tonight if a peaceful resolution couldn't be reached.

Ms Millar says it wasn't a black and white situation, with the bird causing some chaos before coming to rest on top of a chiller.

A Countdown staffer confirmed the magpie did cause some concern for customers, but was safely removed.
