From 1 October 2019, visitors from visa-waiver countries must request an Electronic Travel Authority (ETA) prior to coming to New Zealand. You may also have to pay an International Visitor Conservation and Tourism Levy (IVL). For more information on the ETA and IVL, visit Immigration New Zealand.
You will only need to apply for a visitor visa if you are not from a visa waiver country. Please refer to the Immigration New Zealand website for more information.
