A lightning warning at Auckland Airport earlier this morning has now been cleared.
The airport confirmed to 1 NEWS that all flights will now resume to schedule and all planes can now refuel.

According to NIWA there were 130 lightning strikes in Auckland in a five minute period this morning.
The airport can't say whether the delays are because of lightning.
