From January 2017, Stats NZ compiled overseas merchandise trade (OMT) data using the Harmonised System classification (HS2017). They used HS2017 in OMT from January 2017, and before January 2017, HS2012 applies.
The classification changes mean that data users need to take care when analysing time-series data. As with the change from HS2012 to HS2017, a number of new codes were introduced and a number of codes became obsolete. These changes took effect from the January 2017 month.

For processing purposes, Figure.NZ re-organised this data into one large spreadsheet and built two pivot tables. These pivot tables are annual. They each cover different levels of granularity of trade data (4-digit codes, and 2-digit codes).

Overseas Merchandise Trade statistics provide statistical information on the importing and exporting of merchandise goods between New Zealand and other countries. Merchandise trade includes goods which add to or subtract from the material resources in New Zealand as a result of their movement in or out of the country. Data is obtained from export and import entry documents lodged with the New Zealand Customs Service (NZCS).

The purpose of Overseas Merchandise Trade statistics is to provide statistical information on the importing and exporting of merchandise goods between New Zealand and other countries

Stats NZ obtain data from export and import entry documents lodged with New Zealand Customs Service (NZCS).
They convert export values provided in foreign currencies by NZCS to New Zealand dollars (NZD), using weekly exchange rates when the statistics are compiled. For exports, a rise in the NZD has a downward influence on prices and, as a consequence, quantities and values reduce.
