A grieving man threatened 'to knife' the accused Christchurch mosque shooter as the alleged gunman faced court today. 

Brenton Harrison Tarrant - a 28-year-old Australian man from Grafton NSW - briefly fronted Christchurch District Court on Saturday following a mass shooting at Al Noor and Linwood Majid mosques on Friday afternoon.

Outside of the court a crowd had gathered and one man threatened 'to knife' the accused before police restrained him. 

The member of the public showed a reporter the knife and said of the mass killing, 'What the f*** has happened here?'

Tarrant was charged with with one count of murder but police say many more charges are expected to be laid - he has been remanded in custody and his duty lawyer did not apply for bail.

A second man Daniel John Burrough, 18, has also been charged in relation to the mosque attacks but he did not appear in court.

Another man remains in custody, and police are still trying to 'build a picture of any of the individuals involved and all of their activities prior to this horrific event'.

The terrifying attack at Christchurch was live-streamed in a 17-minute video and it is reported the family of the man charged over the massacre has approached NSW Police. 

'After the crime, my understanding is the family (of this man) did approach NSW Police after the incident was on TV,' Police Commissioner Mick Fuller said in Sydney on Saturday morning. 

Tarrant's mother was nowhere to be seen at her Lawrence home, a 25-minute drive north of Grafton in NSW.

The commissioner will be joined by other senior police at a meeting with religious leaders at the Australian National Imams Council in the city's west. 

Police Commissioner Mike Bush confirmed the death toll stands at 49, with 42 injured.

Earlier, Prime Minister Jacinda Ardern confirmed two of the 36 people being treated at Christchurch Hospital were in a critical condition - a five-year-old had also been taken to Starship Hospital at Auckland.

At the same time, she vowed to strengthen gun laws in New Zealand after she said the attacker had used five firearms in the attack, including two semi-automatic weapons, two shotguns and a lever action firearm.
