For standard airmail delivery, unfortunately we cannot provide tracking information for you.
For airmail with tracking (also referred to as 'airmail track and trace', 'EMS', 'express airmail') you can track your order at the New Zealand Post website, at http://www.nzpost.co.nz/Cultures/en-NZ/OnlineTools/TrackAndTrace/.
For airmail with tracking orders sent to the United States, you can also track your order at the US Postal Service website, http://www.usps.com, although please note that it can take up to a day or two before the USPS site will show tracking information for you.
Courier Express orders can be tracked at the same New Zealand Post website, http://www.nzpost.co.nz/Cultures/en-NZ/OnlineTools/TrackAndTrace/, and the tracking information there may also include a second tracking reference (with URL) for tracking with DHL.
Please send us an email if you have any questions or would like any help.
