An earthquake has shaken the New Zealand city of Christchurch, damaging some buildings but causing no injuries.
The magnitude 4.9 quake struck as shoppers thronged the South Island city for post-Christmas Day sales.
Police say masonry and glass fell to the streets from buildings that were damaged, but no one was hurt.
The earthquake is the latest aftershock from a 7.1 magnitude quake that hit Christchurch on September 4th, causing extensive damage and some injuries. It also came a few hours after a magnitude 7.3 quake struck under the sea near Vanuatu.
