Yesterday, Mr Fisher was called by his excited business partner who told him Twitter had erupted with the news that Bieber had been photographed wearing their obviously Kiwi gear.
"He said to me, 'Bro, we've done it.' And I said, 'Done what?' And he said, 'He's wearing it.' And I said, 'Well who man? Tell me.'
"Then he said, 'Justin Bieber's wearing our singlet - it's all over Twitter."'
But they were just as excited that the 18-year-old star was representing "our small country" by wearing something so identifiable.
In the first five or six hours since the pictures of Bieber in the singlet emerged online, the Jamstreet website had more than 1000 unique viewers.
Mr Fisher and two mates started the clothing company after noticing a distinct lack of New Zealand basketball shirts on the market.
"We were tired of wearing all the foreign shirts that everyone else was wearing, like the Chicago Bulls singlets ... but the problem is you're always wearing other countries or other cities.
"So we thought it was a great idea to wear something a lot more localised which has a lot more meaning.
"We wanted to take baby steps first off, but now it's just exploded which is great."
