Earthquake hits near Christchurch
Wellington - A moderate magnitude 5.0 tremor jolted New Zealand's South Island early on Saturday, 21km from the earthquake-devastated city of Christchurch.
Christchurch was rocked on Friday by two powerful 5.8-magnitude tremors in quick succession, which forced evacuations from buildings.
In February, New Zealand's second largest city was hit by a 6.3-magnitude quake that killed 181 people and destroyed much of the downtown area.
Government seismologists said the latest temblor at 06:37 local time was 7.6km deep.
