Vegetable Research & Innovation

The Vegetable Research & Innovation Board is responsible for the governance of Horticulture New Zealand’s vegetable research and innovation activities.


The core purpose of the VR&I Board is to underpin sustainable growth of the vegetable sector. The VR&I Board aims to achieve this by developing, resourcing and managing a cross-sector research and innovation portfolio and communicating the results of this research to industry stakeholders.


The VR&I Board also represent the combined interests of vegetable sector to New Zealand’s research providers and provides a platform for knowledge sharing and leveraging research and innovation investment in vegetables research.
