Footage circulating on social media from the event showed a heated meeting of the two groups in Albert Park in central Auckland. A man can be seen striking a woman at least twice in the face.
Police confirmed last night that an arrest for common assault had been made but said they could not provide any more information while the matter was before the court.
If convicted of the offence, the man could face imprisonment of up to one year.
After today’s brief hearing, the defendant declined to comment to the Herald as he left the courtroom with his lone supporter.
As the two stepped outside the courthouse, Molloy and two other men - one filming with his phone and another with a small camera attached to a long selfie-stick - followed the man for several minutes as he walked down the block.
“You better get used to this - it’s the rest of your life,” Molloy taunted as he followed the pair.
The businessman stopped after the pair passed a police officer.
“You have no right to stop us,” Molloy told the officer.
“I’m just asking,” the officer responded as the two men with the cameras continued to follow.
Molloy later told the Herald that he had done his best to out the man prior to his arrest and he intended to continue attending his court hearings. Mob violence is reprehensible, he said.
Conditions of the 20-year-old’s bail are that he have no contact with the complainant and he not engage in any violence with people or objects.
