Value of cargo exported by sea from CentrePort (Wellington), New Zealand

Exports (including re-exports) are valued FOB (free on board) and are shown in New Zealand dollars. In some cases, goods are sent on consignment and the selling prices are not known until goods are disposed of at their destination. In these cases, FOB values are based on prices current at the time of export. Values given in foreign currencies are converted by Stats NZ into New Zealand dollars using weekly exchange rates when the statistics are compiled.

From the August 1997 reference month, exports are compiled by date of export. Previously, exports were generally compiled according to date of clearance at the NZCS. This meant that some goods were allocated to the month following their actual month of export. Exports up to July 1997 that were not cleared until August 1997 were assigned to the month of August 1997.

From 1 March 2004, the NZCS does not allow goods to be loaded for export until an export entry has been lodged and cleared. A study undertaken in 2001/02 indicated that export entries not being lodged might account for between 1 and 3 percent of exports at that time. The changed NZCS processes may have reduced this undercoverage, although this has not been quantified.

Overseas cargo statistics, like overseas merchandise trade statistics, are sourced from export and import entry documents lodged with the New Zealand Customs Service (NZCS). The data is processed and passed to Stats NZ for further editing and compilation. Overseas cargo statistics record the value and gross weight of all goods loaded or unloaded at New Zealand seaports and airports.
