"This delayed their arrival into Wellington and there may be some minor delays across our domestic network this afternoon as a consequence."
A social media user said it appeared two planes had aborted landing in Wellington following the quake, one from Auckland and another from Christchurch.
He tweeted the planes began looping around each other over Cook Strait while they waited to land.
Meanwhile, a Wellington resident nearby said she saw one plane appear to abort landing and shoot straight over the airport before landing some time later.
