While the authorities have not released details and information about the victims, his death was confirmed by his son Yama Nabi.
The attack, apparently broadcast live on social media, is the biggest massacre in New Zealand history.
The suspect Brenton Harrison Tarrant has been charged with murder, but the authorities have announced additional charges.
These included, inter alia, nationals from India, Syria, the United Kingdom, Saudi Arabia, Jordan, Egypt, Turkey and Pakistan.
The Pakistani Foreign Ministry tweeted that four of its nationals were injured and five others were missing. The nation's authorities said they are working to identify the victims.
This story will be updated as more information about the victims becomes available.
