ViNa has a Memorandum of Understanding (MoU) with New Zealand Winegrowers to enable a range of collaborative activities that support the recognition of the important of establishing high health and enduring vineyards.

Recognising the importance of high-quality vines and the longevity of vineyards, NZ Winegrowers developed a Grafted Grapevine Standard (GGS) and an associated certification programme which has the objective of minimising the probability of infected material being released to the industry.
