The New Zealand Customs Service conducted a Time Release Study during a week in September 2022.
A Time Release Study is a World Customs Organization method of measuring customs performance in clearing cargo moving across the border, measuring the times of various events and procedures from arrival to release to market.
Customs is just one component in the supply chain and there are myriad factors affecting the international movement of cargo. By measuring performance, it is possible to establish a baseline of indicators, assess effectiveness and identify improvements which help grow the economy by not delaying the delivery of trade.
During this week, Customs analysed data from 12,112 import entries and 5,267 export entries across both sea and air cargo that arrived or departed from New Zealand seaports and airports.
The study also used data from industry partners involved in border clearance, including port and air freight companies.
Import entries that are correctly reported are cleared fast and on average before the arrival of the vessel carrying that cargo.
Exports entries that are correctly reported are cleared in advance of loading for export.

91.5% of import entries for full containers were lodged and released by Customs before arrival into New Zealand.
91.3% of export entries for full containers were lodged 48 hours before loading.
The following diagrams show average processing and movement times for cargo studied during the TRS week. Times for reporting and customs status are overlaid on the physical transport process.

67% of import entries for air cargo were lodged and released by Customs before arrival into New Zealand.*
99.1% of export entries for air cargo were cleared before the departure time of the aircraft.
*On average, import entries for air cargo were lodged and released by Customs 8.5 hours after the arrival of the aircraft. This reflects the much shorter flight times from an overseas departure point to the aircraft landing.

Customs has efficient systems in place to ensure we can process cargo easily
and quickly through the border. This includes:
- electronic reporting
- a risk management and alerts system
- deferred payment and credit facility system
- post-entry auditing capability
- ongoing engagement with industry
If goods are reported to us correctly, they are cleared in seconds.
Findings from this study will be shared with the World Customs Organization and industry.
