A survivor told TVNZ disturbing details of what he saw at one of the mosques.
The unidentified man said he saw the gunman shoot a man in the chest. He estimates that up to 60 people were injured in the shooting which lasted about 20 minutes.
He said the gunman first targeted the men’s prayer room, before moving to the women’s room.
“What I did was basically just waiting and praying, God please, let this guy run out of bullets,” the unidentified man said.
"He came to this side, he shoot this side, he went to another room and went to the ladies' section and shot them. I just heard one of the ladies has died."
