New Zealand has been hit by hundreds of strong aftershocks since a massive 7.8 magnitude earthquake struck in the early hours of Monday.
The initial quake damaged roads and buildings, and sparked a tsunami warning which sent thousands of people fleeing to higher ground.
It was originally measured at a magnitude of 7.5 and killed two people, including one of a heart attack.
As dawn broke on Monday, emergency teams flew helicopters to the areas thought to be worst-affected by the quake, which had
its epicentre about 57 miles northeast of Christchurch in the country’s South Island.
A military helicopter and surveillance aircraft were sent to the small coastal town of Kaikoura, which was left inaccessible by road.
