"Me and my friends are really big fans, so we thought it was worth a try," Dana said.
"But we thought we would be left with a kilo of kina. We didn't think we would get to see them.
"We saw Dagg and told him about it. He was really shocked. He didn't know what kina was. So he texted Piri and he came down. It was really cool.
"Piri was really surprised. He was like, 'You guys actually did it?' It was really exciting."
It was "probably the best day of my life", Dana said. "It was really, really cool. I'm sort of still a bit shocked. I wish I could relive that moment over and over again."
Weepu earlier took a stroll through the Viaduct with his family, disguised in a hoodie and sunglasses.
Many of the other All Blacks - including Ma'a Nonu - also met friends and relatives or chatted over coffee.
All Black captain Richie McCaw had a mostly quiet day, shopping in the early afternoon, and returning to the hotel with a grocery bag of supplies.
Later, he went out with fishing expert Geoff Thomas, apparently to get some fishing gear.
The All Blacks get down to more serious business today, with a full training run at Trusts Stadium in Henderson at 4pm.
And McCaw's parents, Don and Margaret, arrive in Auckland today to support their son in Sunday's World Cup final against France.
They know the All Black captain already gets enough advice and rugby talk, and will "just try to branch away from it a bit", Don McCaw told the Herald. "I always just say 'good luck'."
"I would be very, very relieved if they won. I know it has been a goal of Richard's since he started with the All Blacks, to win the World Cup. And I know how much it means to him.
"I did speak to him earlier in the week briefly and I don't think there is any way they are taking this lightly.
"I heard a comment - I don't know if it was from him - but this game this week will be as tough, if not a lot tougher, than the one last week against Australia. So that's what they are expecting."
