The GST data presented in the accompanying tables and graphs only includes net GST collected by Inland Revenue. GST collected on imports by the New Zealand Customs Service is not included.

GST turnover values presented in the accompanying tables and graphs are calculated from GST returns as the sum of gross sales in the year ended 31 March. For a 2-monthly filer this would mean the sum of gross sales on 6 successive GST returns, with the last return being for the period ending 31 March. Customers with no turnover returned to Inland Revenue are either not trading or have input credits but not output tax to be declared to Inland Revenue in that year. They may have paid Customs GST on imports.

From 1 October 2010 the rate of GST was increased from 12.5% to 15%.
