Qatar Airways' flight QR920 has landed in Auckland on Monday morning after crossing 10 time zones without stopping from Doha.
It's billed as the longest commercial passenger flight in the world and arrived shortly before 7.30am at Auckland International Airport.
The route launches with a 777-200LR aircraft on a daily service that will add $198 million annually to the New Zealand economy, the airport says.
The route covers 14,535km and the flight takes as long as 17 hours 45 minutes when flying into prevailing jet streams to Doha.
It's slightly longer than the service operated by Emirates to Auckland from Dubai.
