A new winery is being built next to Te Awa Winery Restaurant, which involves shifting Vidal Estate's cellar door and wine making.
The new facility will incorporate the brands under Villa Maria Estate including Vidal, Esk Valley, Villa Maria and the Te Awa Collection.
Despite the cellar door and wine making from Vidal moving to the winery, it wasn't yet decided whether the restaurant, which had been based in Hastings since 1979, would close.
A Villa Maria spokesperson said there were no current plans to close it but everything was still being confirmed and finalised.
"We're not entirely sure, it's possible we may keep it open or it's possible we may not."
