True, but I doubt anything but the most low grade black hat intel is sent via FedEx nowadays as the risk of direct interception by white hats has greatly increased. With their comms compromised they're returning/returned to the old spy tradecraft ways of direct meetings, dead drops, verbal only messengers etc for the most important intel. FVEY intel would be right up there and even though NZ may be 'out' of FVEY now there's absolutely nothing to stop them from continuing to spy for the Cabal.
Do you think they’d still continue to FedEx? If so why?
Very nearly EVERYTHING digital in and out of NZ passes through the Southern Cross cable upon which the NZ GCSB has a tap. They monitor it and after law changes made by the former NZ PM Sir John Key they can also spy alongside the NZ SIS on any NZ Citizen/resident/visitor too.
