If i buy an iPhone 5s from the United States will the iPhones warranty be honoured in New Zealand?
Warranty for the iPhone is not and has never been International.
Purchase the device in the country where it is intended to be used.
Also, be aware that there is no gurantee that an iPhone from the US will work on LTE anywhere else in the world.
30 seconds of searching the forums would have revealed that the answer is no.
