One-fifth of New Zealand vineyards will be organic by 2020 if an association of like-minded local growers has its way.

Organic Winegrowers New Zealand (OWNZ), a 140-member body, yesterday announced a campaign to get 20 per cent of this country's vines organically grown over the next nine years.

The group has signed a memorandum of understanding with New Zealand Winegrowers, another industry organisation, to promote organic production through education, research and marketing initiatives funded by wine industry levies.
