WELLINGTON: The earthquake-rattled city of Christchurch has been shaken by another powerful temblor.
The magnitude 4.7 quake struck just after 8:30 pm on Sunday and there were no initial reports of significant damage or injuries.
The country's Prime Minister John Key was in Christchurch watching a televised All Blacks rugby match with other fans at the time. The game was being played in Auckland.
Christchurch has been struck repeatedly by earthquakes over the past 13 months, including a devastating magnitude 6.1 quake that struck Feb 22 and killed 181 people, and destroyed much of the city's downtown.
Sunday's quake was the largest since June.
