Most NZ ETA applications should get clearance without delay. However, in some exceptional cases, a few applicants may find their ETA applications have been refused because of the reasons like health, past criminal record, job-related aspects, etc.
If you see your NZ ETA application is denied, it only means the ETA permit cannot be issued to you.
In the following situations, you will have to opt for a new NZ ETA application even if you have an existing and valid ETA:
If you get a new passport and your NZ ETA is linked to the older one.
If you have opted for a name change.
If the address in your passport is no longer valid or you have moved to a new place.
If you have become a citizen of another country.
If any of the answers to the online application questions have changed.
