The wine industry says a new international labelling agreement will help with market access and cost reductions.
New Zealand belongs to the World Wine Trade Group, which is made up of eight countries that do not belong to the European Union.
New Zealand Winegrowers chief executive Philip Gregan says the group's new protocol on labelling is all about easing trade between the member countries, who now account for almost a third of global wine exports.
He says the group already has a labelling agreement in place but the new one covers previously unaddressed issues such as multi-varietal labelling, multi-region labelling and vintage declarations.
Mr Gregan says it's about establishing a benchmark across all the countries so that labels being used by wineries in - for example - New Zealand can be used in exactly the same way in the United States.
Mr Gregan says he hopes other markets will adopt a similar approach.
The members of the group are Argentina, Australia, Canada, Chile, Georgia, New Zealand, South Africa and the US.
