The son of a Christchurch terror attack victim says mass murder is "not what people do".

Omar Nabi told Newshub his 71-year-old father was killed in one of the Christchurch mosque shootings on Friday.

Forty-nine people died in the attacks, which targeted mosques on Deans Ave and Linwood Ave.

"My father always helped people, my father was a Muslim leader, one of the first people that opened a mosque here on Tuam St.

"People were praying, people were praying at their mosque they got shot in the back. This is not on this is not what humans do."

Nabi said his father was usually at the front of the mosque, but Friday was an exception.

"He was late. He was at the back of the row. He leaped on somebody to save their life, he was 71 years old. Very highly respected in the community. There's no words."

Three people have been taken into custody over the attacks. A 28-year-old man has been charged with murder. He will appear in the Christchurch District Court on Saturday.

A further 42 people have been injured, two of them are in a critical condition as of Saturday morning. One of the critical is four years old.
