My NZeTA expires in early February. I'd obtained it for a trip to NZ in March 2023 when I stayed for 2 months. I'm due to travel back to NZ for 4 weeks in January, with my return flight to the UK due to leave Auckland on 25 Jan. This means the current NZeTA covers my entire travel period.

Am I safe to travel on my existing NZeTA or should I arrange to get another. I certainly don't want any issues when I arrive at Immigration at Auckland airport!

its usual for those type of travel docs to last for all trips done in the time frme
