The show follows a couple named Samantha and Ryan, who move into a country house that happens to be falling apart and inhabited by the ghosts of former residents.
McIver's character Samantha is a freelance journalist and her husband Ryan is a sous chef. The couple jump at the chance to move to the country estate so they can ease up on work and live rent-free, according to Deadline.
McIver played the lead role in Rob Thomas's zombie comedy iZombie for five seasons from 2015-19. She's had several successful acting roles over the years, including Tinker Bell in CBS's Once Upon A Time, Queen Amber in Netflix's A Christmas Prince franchise and Lindsey Salmon in The Lovely Bones.
Last year she starred in Daffodils, a musical that reimagined iconic New Zealand songs.
She told TimeOut while promoting the film: "We're pretty guilty of cultural cringe in New Zealand, and we're not very keen to look at ourselves on screen a lot of the time, and I think that some of the amazing stories that this country has to share have been hidden because of that."
