Mine was shipped with UPS (domestic for me), Trevor mentioned it in an e-mail.
If you got a notification e-mail about the shipping with a tracking number then have a look at the fine print .
In case you only have a tracking number just try different carrier tracking sites : UPS, FEDEX, your local NZ postal service.
If it's not in their system you will just get a "not found" message.
And of course you can always ask Trevor directly...
