The couple said they were delighted Mr Day had agreed to create the sculptures.
"He is widely regarded as one of the world's best sculptors, but has never had a piece commissioned outside of the Northern Hemisphere," Mr Peabody said.
Mr Day said he was thrilled to create the works as they offered a unique connection between the old world and the new world - he has charolais cattle grazing near his home in Burgundy, which is one of the hearts of old world winemaking.
"These statuesque and magnificent creatures live alongside wine country in France so there is nothing unnatural about seeing them among the vines at Craggy Range in Hawke's Bay."
After the unveiling Queensland-based art dealer and patron Philip Bacon will host a discussion with Mr Day and Craggy Range chief winemaker Matt Stafford on landscape and agriculture, and how it affects them in their own areas of individual "artistry".
Craggy Range is staging a four-course wine-matched dinner at the Terroir Restaurant to complete the occasion, although tickets are limited.
