Sophie Cooper (17), James Daly (18), Annabel Dickson (17), Caitlin Jack (17) and Phoebe Lynes (17) were all smiles when they stepped out of their rain-soaked, makeshift home at noon.
They began their test on Friday at 8pm with only barley sugars, fruit juice, warm clothes, board games and mobile telephones to sustain them.
The sponsored teenagers welcomed donations in a collection box, which was emptied regularly by supporters, and by eftpos, in aid of World Vision irrigation projects in Mali and Niger.
The total amount was likely to be known by tomorrow or Wednesday, but at least a bucketful of coins had been collected.
Caitlin said it had been "really interesting to watch the stages of Queenstown, from sober to not really.
"Some of them were scary, some of them were lovely."
Daytime passers-by were curious and talkative, but more donations were given by pedestrians on their night out, at about midnight.
Some pedestrians tried to feed them chips through the wire and coin pipes.
"We went through a bit, but it wasn't as bad as we thought," James said.
"Some people jumped on top and rattled the cage and poked us with straws around the 3am mark.
"We got some abuse from somebody who said we should be helping people in New Zealand, but they are not as worse off [as Africans]."
The youths said they did not feel too hungry after their fast, but they still looked forward to a cooked brunch in a nearby warm cafe.
