You'd be surprised. Overall fedex etc are a bit faster than NZ Post when it comes to moving packages between countries, BUT their local customs brokers are often totally useless. E.g. we had to stop offering Fedex for USA deliveries because we were requested by Fedex to file 2 extra forms and do 20 minutes worth of paperwork to accompany every parcel. And the clearance still took 2-3 extra days. No such issues with NZ Post/USPS.Just don't compare courier's like fedex or ups with the postal service.
