Cable Bay Vineyard and Restaurant on Waiheke Island has been sold to its founder and a construction boss.
Winemaker Neill Culley, who planted the first vines there in 1998, said he and Canam Construction managing director Loukas Petrou bought the property on Friday.
But he refused to disclose the price.
QV lists the property as being worth $5.5 million, made up of buildings worth $3.5 million and $2 million of land.
Mr Culley said he had a small shareholding previously but in his new role, he hoped to promote the brand in Australia, Singapore, Japan, the United States and elsewhere.
