Bieber touched down in Auckland late Wednesday night for a three-day promotional visit.
The number of retweets caused British TV minor celebrity Katie Waissel to tweet: "His followers are clearly braindead prepubescent sheep."
Bieber's record company Universal is keeping tight-lipped about his movements while he's in Auckland.
He last visited New Zealand in April 2010.
A clip of a Bieber song surfaced on You Tube on Friday, believed to be from a private show for 200 winners of a competition run by Skinny Mobile, Westpac and media companies.
