From an international perspective, New Zealand's arable industry could be viewed as small, with 2,500 farmers and revenue of approximately $5 billion. However, the industry contributes extensively to the New Zealand economy. Many Federated Farmers provinces have a Arable chairperson who leads a local group of growers. These groups tend to deal with local issues such as stubble burning regulations, Resource Management Act compliance and local product contracts. They also feed information back into the national network.
