Hi I cannot seem to find the following information on NZ immigration website.
I am US passport holder so I won't need a visa to visit NZ up to 3 months period. During my visit, I'll be landing in Auckland, then I'll be going to Australia with my relatives. Then come back to Christchurch to spend time with my relatives. Knowing that I'll be "double" entering NZ, would that cause any issues? Will they stamp my arrival and departure twice then?
