New Zealand generates a small but consistent volume of urgent traffic in three areas. Agricultural technology and dairy processing produce equipment and sample movements with American partners; marine and boatbuilding produce parts against launch and delivery dates; and film production produces camera, lens and post-production equipment moving against shooting schedules that cost a great deal per day.
The film strand is the one where hand carry earns its keep most obviously. A camera body, a lens set or a drive of rushes has a shooting schedule attached, the equipment is valuable and delicate, and most of it is going back afterwards, which makes carnets and temporary import the whole administrative story.
The constraint on this lane, as in Australia, is biosecurity rather than customs. New Zealand takes it extremely seriously and applies it to a wider range of goods and packaging than American shippers expect. Checking the commodity and the packing before departure is not a formality here; it is the difference between clearing in an hour and clearing in a week.
