A winery has lost 6000 litres of merlot after vandals opened a tank valve and left it to drain.
Staff at Moana Park at Puketapu, near Napier, arrived on Saturday morning to find $165,000 of wine spilled onto the ground.
Owner and winemaker Dan Barker said the loss was "gutting" and had put a valuable Japanese contract at risk.
The wine was heading for a supermarket chain in Japan, and the buyer was at Moana Park the morning the vandalism was discovered.
"It's three-quarters of a container of wine not going to Japan now," he said.
