This week's storm was so strong that it downed a king pin - the flag on New Zealand's tallest flagpole.
An Auckland Airport spokeswoman said the flag at the airport at Mangere was brought down during the storm but the airport's focus had not been on rectifying that immediately.
"It's down due to the storm damage. Our focus is very much on assisting passengers experiencing delays," she said on Wednesday.
The huge flag usually flies atop the 45m flagpole, the tallest in New Zealand and at around 14m by 7m, it is a landmark visible from as far away as One Tree Hill.
