Mairaj, who is president of the Islamic Association of Whanganui, said he is still heartened to remember how the community rallied around local Muslims.
"It is still a concern that something like that could have happened in New Zealand and it was disturbing to learn about a masked man making threats outside the Al-Noor mosque in Christchurch last week."

As a doctor working at Whanganui Hospital, Mairaj says he struggles to understand bigotry.
"When I attend to a person's medical needs I don't think about their beliefs or their race," he said.
"I just think of them as human and I can't understand how a person could feel such hatred towards other members of humanity."
The anniversary of the terror attacks coincides with Race Unity Week and New Zealand's Race Relations Commissioner, Meng Foon is visiting Whanganui this weekend will be a guest in the UCOL atrium on Saturday morning.
