Asking a very similar question to this Do you get another 6 months on each visit to New Zealand? however I am a US rather than a UK citizen so my visa waiver visa is a shorter duration than that for a UK citizen, which leads me to question what other terms of the visa might also be different.
Specifically, I am in New Zealand on a 3 month visa waiver visa, and have been asked to return to the US for a brief (5 day) stay, after which I would return immediately to New Zealand.
I am a bit concerned by the line from this page of guidelines https://www.immigration.govt.nz/new-zealand-visas/apply-for-a-visa/tools-and-information/general-information/variation-of-conditions-temporary-visas/varying-a-visitor-visa which reads, "Your visitor visa expires when you leave New Zealand."
As I am going to leave my wife in place in NZ with the bulk of my luggage, and because there is a chance I can whine and complain my way out of this trip to the US, references to official NZ government regulation or documentation would be greatly appreciated. I have not been able to find such clarity myself.
