The Agricultural Production Surveys and Census include all units identified on Statistics New Zealand's Business Register as having agricultural activity. The Business Register 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 Register 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.
The compulsory registration level for GST is $60,000 so there is a partial and unquantifiable coverage of units below this level.
The eligible population when the survey was selected was 52,300 geographic locations.en-NZ
