Mr Adeeb Sami's trip to New Zealand was supposed to be joyful - a chance for the Dubai-based father to surprise his twin children in time for their birthday. The couple was due to fly out Sunday.

New Zealand Prime Minister Jacinda Ardern has confirmed her office was one of more than 30 recipients of a so-called manifesto written by the accused Christchurch shooter, sent nine minutes before Friday's mosque attacks.

During a Saturday press conference, Ardern said the gunman had two semi-automatic weapons, two shotguns, and a lever-action firearm (five firearms in total).
