New Zealand’s Prime Minister Jacinda Ardern appeared awestruck as she stood in the Antarctic hut of explorer Sir Ernest Shackleton during a rare visit to the continent by a world leader.

Speaking from inside the hut that was built more than a century ago, Ms Ardern said: “I think when you’re a kid and you read stories about Shackleton, you’d never imagine you’d have the opportunity to come. So, I feel pretty lucky.

“It’s a cool place.”

She is due to return home on Saturday.

She said it was important for New Zealand to maintain a leadership role on the continent.

“We’re in a period where internationally you see that parts of the world are becoming increasingly contested, and Antarctica is part of that, too,” Ms Ardern said.

She said she did not exactly draw parallels with her own leadership.

“I don’t think I can quite compare government with the hardship and endurance of Antarctic exploration,” she said, before adding with a laugh: “But, some days…”
