Christchurch terror attack: Chris Bishop tells racist Aussie Senator to 'f**k off'

National MP Chris Bishop is receiving praise after sending an expletive-filled tweet to an Australian Senator who blamed Friday's attacks on Islam.

Forty-nine people were killed when armed killers stormed two mosques in Christchurch. Three people are in custody, and two victims remain in a critical condition.

Queensland's Fraser Anning took to Twitter as the news broke, asking followers: "Does anyone still dispute the link between Muslim immigration and violence?"

In a statement he said the "real cause of bloodshed on New Zealand streets today is the immigration program that allowed Muslim fanatics to migrate to New Zealand in the first place", and said calls to toughen gun laws or blame people with "nationalist views" was "cliched nonsense".

Among those outraged at the independent Senator's comments was Bishop, who kept his outrage succinct.

"F**k off," the Hutt South MP and National spokesperson for police said.

Twitter users from all political walks of life backed Bishop.

"I agree with you totally, btw. For once," wrote @MariaSherwood2.

"Not often we agree, Christopher, but in this case, WELL SAID MATE!!!" said @fmacskasy.

"You know it's a weird day when I wanna high-five a National MP, but high-five, Chris," added @DeaExLena.

Anning deleted the tweet quoted by Mr Bishop, but reposted it later with the exact same wording.

Australian Prime Minister Scott Morrison condemned Anning's remarks.

"The remarks by Senator Fraser Anning blaming the murderous attacks by a violent, right-wing, extremist terrorist in New Zealand on immigration are disgusting," he tweeted.

"Those views have no place in Australia, let alone the Australian Parliament."

Auckland Mayor Phil Goff told Anning he was an "embarrassment".
