Daniel Nicholas Tuapawa, 33, is alleged to have hurled Islamophobic abuse last Wednesday evening. He was wearing a black T-shirt emblazoned with the word “Trump” at the time, police said.
“The community is understandably shaken by this behavior,” said Canterbury District Commander Superintendent John Price, adding that two armed officers had been outside the mosque at the time.
Australian Brenton Tarrant, 28, a suspected white supremacist, has been charged with 50 counts of murder after the attack on the Al Noor mosque and another mosque on March 15.
“Our community has no tolerance for those who target or victimize others because of their identity, and nor does the police,” said Price in a statement. “This is especially so for members of our Muslim community who are already dealing with so much.”
A court spokeswoman confirmed that Tuapawa had pleaded guilty. CNN has reached out to his lawyer for comment.
