Tongan captain Finau Maka addressed the crowd at Westpac Stadium in his mother tongue. He told fans: "Thank you to the father and thank you to the prime minister and thank you to all the church leaders. Thank you to all of the people of New Zealand and Tonga, I love you all.
"That's all we can do. That's our best and we hope people are happy for what [the team] has achieved. I love you all."
The French press gave the national team a caning. Le Monde called it "one of the most humiliating defeats in their history". Le Figaro said it would leave a "sense of shame". It was even worse than losing to Italy in the Six Nations, the paper said.
Overjoyed Tongan fans at The Cloud in Auckland included George Vakamilalo. "Otahuhu's going to be like Nuku'alofa tonight," he said.
Mana Saulala, waving his flag as the final whistle blew, said: "Our island is such a small island," he said. "We didn't expect we were going to win."
Mele Pope drove up from Hamilton with her friends to watch the big game. "Even though it was a cold night and we could have watched it at home on TV, we chose to waste our petrol and drive up here to support Tonga."
Pope's friend Taisa Manuopangai, a Waikato University student, was over the moon. "I'm just so proud of the Tongan team right now."
In Nelson, police said crowds at the Australia-Russia match were well-behaved, but officers were investigating an assault on a tourist reported after the game.
Many of the minnows have already begun their journeys back to day jobs. Romania returned home on Friday, Namibia on Tuesday. Georgian team spokesman Lasha Khurtsidze said his team would be hitting the town in Palmerston North after their final game against Argentina today.
