Irrigable land in farms engaged in the floriculture production industry (outdoors) in New Zealand

Farm: For the purposes of this census a farm is one or more blocks of land, managed as a single operation, that is engaged in agricultural activity. This includes farming of livestock, horticulture, viticulture, nurseries, forestry, growing grain and seed crops, and land that could be used for these purposes.

Irrigable land area: land area that could have been irrigated using existing resource consents and equipment that is on the farm. Irrigable area may be irrigated by more than one system.

Figures may not add to the totals due to rounding.
Farm types are classified according to the Australian and New Zealand Standard Industrial Classification 2006 (ANZSIC06).

The compulsory registration level for GST is $60,000 so there is a partial and unquantifiable coverage of units below this level.

The Agricultural Production Surveys and Census include all units identified on Statistics New Zealand's Business Frame as having agricultural activity. The Business Frame is a list of businesses in New Zealand, based on their registration for goods and services tax (GST) with Inland Revenue. In the case of agriculture the Business Frame includes the following units: - those units registered for GST (and filing a non-zero GST return) that have indicated involvement in agricultural activity (as defined above) - those businesses with more than $200,000 of GST sales or purchases, or that are an employer, whose main activity is not agriculture but have indicated some secondary agricultural activity.
