WATCH: Intense Haka to victims of the Christchurch Terror Attacks

Last night, as mourners stood silently by the floral tribute outside the Al Noor mosque in Christchurch, a man performed an emotional haka. 

A video of the powerful performance, which was a tribute to the people who tragically lost their lives, has gone viral on social media.

The shootings, which occurred on Friday, have left 50 dead and more than 30 still in hospital.

They were carried out with military-style, semi-automatic weapons, police said.
