"I'm sure the Eden Park locals would probably have something to say," said Ardern, who added the priority was dealing with "congestion" as they sought to bring Kiwis home.
Ardern said: "If the NRL put a suggestion to us, I'm sure we would give it due consideration. But those are all the factors that we would weigh up, and it would be a hard ask."
V'Landys fears the grand final TV experience will be wrecked it the big game is played at an empty stadium in Sydney, Melbourne or Brisbane.
