Riversun Nursery Limited is a Gisborne nursery established in 1982. Public information describes it as New Zealand's leading supplier of certified grafted grapevines to many of the country's vineyards, as well as a supplier of certified avocado trees and kiwifruit vines.

The core range is plant material rather than hospitality consumables. Key categories include grafted grapevines, Supervines, avocado trees, kiwifruit vines and other horticultural stock for growers and vineyard operators.

Riversun publishes certification information, including production under the New Zealand Winegrowers Grafted Grapevine Standard and its own HACCP standard. Ordering is specialist and seasonal, so buyers should confirm stocklists, specifications and dispatch timing directly.
