From 1 October 2019, visitors from visa waiver countries  (external link) (including Korean nationals) travelling to or transiting in New Zealand require an NZeTA (New Zealand Electronic Travel Authority).

You can request your NZeTA via the official NZeTA mobile app (downloadable from App Store and Google Play) or the official government website (external link). Approval for the NZeTA can take up to 72 hours, so do remember to apply for it well in advance. The NZeTA requested via the NZeTA mobile app will cost NZ$9 and the NZeTA requested via the website form will cost NZ$12.

Additionally all visitors (except Australian citizens), are required to pay the International Visitor Conservation and Tourism Levy (IVL). The IVL is aimed at maintaining and protecting the tourism infrastructure and natural environment in New Zealand. It will cost NZ$35 and is payable at the same time you request the NZeTA.

Both the NZeTA and IVL are valid for multiple entries over two years.
