Quick answer
For a trip involving Auckland, Christchurch, Queenstown and long road sections between towns, the most reliable approach is to install your travel eSIM before departure, keep the QR and essential bookings offline, and switch mobile data to the eSIM when you need it after arrival. New Zealand rewards road travel, but long distances and sparsely populated areas make offline preparation more important than assuming continuous signal.
