Disturbing footage has emerged of the terrifying moment a masked gunman storms a Christchurch dairy - and a worker bravely tries to fight him off.
The owner has his back turned to the door when the masked man burst into the Kidbrooke Street dairy at about 7:35am.
The gunman then ushered the owner over to the cash register before a scuffle broke out and the pair fell to the floor.

The owner then grabbed a bar and swung it at the robber, who scrambled back over the counter and out of the shop.
