Where the NZ Government has needed to contact New Zealanders who are thought to be in an area affected by a cyclone, bomb blast, or other major incident overseas, those who have registered their travel contact details have often been accounted for first.
So, no matter where you are travelling to overseas, if you take the time before you leave NZ to register, then you can be assured that if an emergency situation develops in the country you are in, the NZ Government will do their best to contact you and see if they can provide any assistance.
