Visa & Entry

US passport holders enter New Zealand visa-free for up to 90 days. Before travel, apply for a New Zealand Electronic Travel Authority (NZeTA) at nzeta.immigration.govt.nz or through the NZeTA app. The NZeTA costs NZD 17 ($10) via the app or NZD 23 ($14) via the website and is valid for 2 years. An International Visitor Conservation and Tourism Levy (IVL) of NZD 100 ($60) is paid at the same time. Passport must be valid for at least 3 months beyond the planned departure from New Zealand.

The NZeTA is not a visa but an entry screening requirement. Processing takes up to 72 hours, so apply before booking flights. At Auckland Airport (AKL), Christchurch (CHC), or Wellington (WLG), immigration checks your NZeTA electronically and stamps your passport.
