Thank you for the email address for immigration - I'll try sending them a quick email and hope for a definitive answer. I too think the issue will be with the airline; will likely just go ahead with the ETAs if I'm feeling risk averse lol. Thanks again!
In my opinion the NZeTA applies for people arriving/transit from 0:01 01 Oct 2019. That is when the new law will apply. The NZ Government text about
'leaving from" are IMHO just very poor text by some government muppet. Especially for flights from USA where you can skip a complete calendar day, due to crossing the international date line. That text will cause problems.
Will be fun & games a for people flights arriving/transit up to 23:59 30 Sept / from 00:01 01 October.
I often take a flight to NZ that has a scheduled arrival of 23:55. I can be through the immigration e-gates before or after midnight depending on if the flight is early, on time or late.
