The service from New Zealand Post tracks parcel delivery for most categories of packages carried by the postal network. It is intended for integration with e-commerce websites and other applications that need parcel tracking. Tracking notification and shipping/rate lookup APIs also are available.
Tracking API methods support submission of a single tracking code or multiple codes in a single request. Methods are available to submit mock requests without valid tracking codes to verify service output and to simulate various error conditions to help program application responses.
