Those kids interrupting a BBC interview have become famous, yes, but it doesn't get more disruptive than an earthquake during a live interview.

New Zealand Prime Minister Jacinda Ardern was in that very scenario this morning. She totally kept her cool when an earthquake, reported to have a magnitude of 5.8, struck near Levin.

"We're just having a bit of an earthquake here, Ryan," Ardern told Auckland-based AM Show presenter Ryan Bridge. She smiled while scanning the room around her.

"Quite a decent shake here, if you see things moving behind me," she said, quickly regaining composure as she continued the interview.

"It's just stopped," she said. "We're fine, I'm not under any hanging lights, I look like I'm in a structurally sound place."

It really is something.
