To enter New Zealand in 2026, you must hold a valid passport with at least three months of validity beyond your intended departure date. For most travelers from "visa-waiver" countries (including the USA, UK, and Canada), you do not need a traditional visa for stays up to 90 days, but you MUST apply for an NZeTA (New Zealand Electronic Travel Authority) before you arrive. This digital authorization is usually processed within 72 hours and is valid for two years. Along with the NZeTA, you must pay the International Visitor Conservation and Tourism Levy (IVL). You will also need to complete a New Zealand Traveller Declaration (NZTD), which is primarily used for biosecurity and customs purposes; this is often done digitally via an app before landing. New Zealand is world-famous for its strict biosecurity, so you must declare all food, outdoor equipment (like hiking boots), and animal products. Finally, you may be asked to provide proof of a return or onward ticket and evidence that you have sufficient funds to support yourself during your stay.
