A group of Hardy Wines workers have voted to accept the company's pay offer and end industrial action, according to local reports.

Three-quarters of employees at Hardy Wines' Berri Estates winery in South Australia have accepted the company's offer of an annual wage hike of 3.5% for three years.

Mark Butler of the Liquor, Hospitality and Miscellaneous Union told ABC News that members agreed to the deal in the context of changes to the industrial relations system.

"The pragmatic view was taken that this was the most sensible outcome for the next few years in all the circumstances," he said.

Hardy Wines MD David Woods said he was pleased the offer has been overwhelmingly accepted by workers and that industrial action has come to an end.

He added: "I think the way the dispute has been settled has been a credit to those involved and is a realisation that the industry is going through a challenging period and that everyone has to play a part in helping us get through that."
