At the same, he underscored that he is "utterly opposed to any form of violence within our community" and that he "totally" condemns "the actions of the gunman".
"The remarks by Senator Fraser Anning blaming the murderous attacks by a violent, right-wing, extremist terrorist in New Zealand on immigration are disgusting".
"Senator Fraser Anning has no place in the government of our democratic and multicultural country".
He went on to claim the real cause of the bloodshed that's left at least 49 people dead is New Zealand's immigration policy. In his statement, he said that Islam is a religion equivalent to fascism.
Calling the religion as a violent ideology, Senator Anning said that Islam is a violent ideology of a "despot" acting as a religious leader.

Following the backlash, senator Anning deleted many aggressive and discriminatory tweets from his personal account.
Australia's prime minister, Scott Morrison, called Anning's comments "disgusting".
Dr Jneid urged all governments to give extra attention to the rise of anti-Muslim sentiment and extremism and also encouraged all mosques and places of worship and Muslims in Australia to be extra vigilant in the coming days.
In August, he called for a "final solution" to the Muslim "immigration problem", evoking a reference to the Nazis' "final solution" terminology used to target Jews during the Holocaust.
"While families in Christchurch mourn for loved ones they've lost, an obscure Australian Senator saw this act of terrorism and tragedy as an opportunity to blame the murder victims", Mr Shorten said.
A staffer for Senator Anning then separates the senator from the young man, while supporters of the senator tackle his attacker to the ground.
Fraser also tweeted a number of Islamophobic messages on Friday in the hours after the attack. The mosques were full of worshippers attending Friday prayers.
