If the show goes well it is hoped the event will become an annual feature on the local event calendar.
Promoter Jackie Sanders of Jacman Entertainment was in Havelock North to scout out the fresh venue last week.
"We thought it would be the smallest concert on the tour but it's shaping up to be the biggest - it's going to be quite incredible," Ms Sanders said.
"Two thirds have already sold to the new venue. Given we are still six months out it's likely to sell out - we will put a cap on it.
"We don't want this to be standing room only."
Organisers have allowed plenty of space for people to lay out a picnic rug and ample parking for cars or busses.
Those who bought tickets to the original venue have been rewarded with a premium seating area, private bar and space to bring beanbags or other seating.
A wristband will allow them to join an express queue at the gate and give them access to parking.
Bars and eateries will be clustered in village-like areas for a festival feel. Kiwi support acts are on track to be announced in coming days.
"It's a beautiful space, just really stunning we can do a lot with it," Ms Sanders said. "Obviously its just hit the nail on the head for what people want - this isn't a reggae concert, it's a winery concert with a great 80s band."
Many people from throughout the North Island and top of the South Island have expressed interest and Black Barn hopes an estimated 30 per cent of those attending will be from out of town.
Moving to a spacious riverside spot allows organisers to more than double capacity and release a swag of extra tickets.
