Area planted for onion production on Māori farms in New Zealand

Farm: denotes one or more blocks of land, managed as a single operation, engaged in agricultural activity. Activities include livestock farming, horticulture, viticulture, nurseries, forestry, growing grain and seed crops, and land that could be used for these purposes.
Māori farms: identified by matching the Agriculture Production Survey to the list of Māori enterprise found defined as Māori authorities, the list of self-identified Māori business or through partner Poutama Trust. The majority are Māori authorities and a small minority are from the other sources.

Māori authority: having a Māori business flag on the Business Register. This flag denotes:
• business with a collectively managed asset, which uses current Inland Revenue eligibility criteria to be a Māori authority (irrespective of whether the enterprise elects to be a Māori authority for tax purposes)
• commercial business that supports the Māori authority’s business and social activities, and sustains or builds a Māori authority’s asset base
• business that is at least 50 percent owned by a Māori authority.
