The character is described as a "gregarious, single-and-ready-to-mingle" Sydney socialite who has never worked a day in her life.
Edwards played Martin Charteris on seasons three and four on The Crown, and fans of Downton Abbey may also recognise him from his role as Michael Gregson.
In a statement, Gibney expressed she is "beyond excited" to film Under the Vines in New Zealand. The Kiwi-born actress executive produced the series, and said there is "so much humour and heart" in the story.
"We could all could do with some cheering up! The character of Daisy is totally unlike anything I have done before and I can't wait to work with the fabulous Charles, our extraordinary cast and a world class team of New Zealand creatives," she added.
Under The Vines will air on streaming service Acorn TV worldwide, but it will be broadcast on TVNZ in New Zealand.
Production is set to get underway in early February 2021 in Central Otago.
