The gunman at one mosque was an Australian-born citizen, Australian Prime Minister Scott Morrison said in Sydney, describing him as "an extremist, right-wing, violent terrorist".
He livestreamed the dastardly act on Facebook. The video showed him repeatedly shooting at worshippers from close range.
The Facebook Live video, taken with a camera that appeared to be mounted on the gunman's body, shows a clean-shaven, Caucasian man with short hair driving to the Masjid al Noor mosque in central Christchurch. He enters the building and fires repeatedly at worshippers as he moves from room to room.
In the video, the shooter parks his car next to the mosque and gets out of the vehicle with a rifle. He slowly goes to the boot of his car and retrieves another firearm.
He then walks into the compound of the mosque and fires at a person standing near the doorway before dropping the rifle and shooting repeatedly with the second weapon as he moves inside.
The gunman fires dozens of bullets at people trying to run away or lying down in huddled groups in corners of the rooms.
Approximately 200,000 Indian and Indian-origin people live in New Zealand. There are over 30,000 Indian students in the country, according to the Indian High Commission's data on its website.
