A major 5.8 magnitude aftershock has rocked New Zealand's South Island, north of where two massive earthquakes measuring 6.3 and 7.8 struck less than 24 hours before.
The recent 'strong' quake, which was 35km deep, hit the Kaikoura region at about 7.45 local time on Monday.
An intense 6.3 magnitude aftershock centred in Cheviot, located between Christchurch and Kaikoura, also hit around 1.30pm local time on Monday.
They are included in close to 400 aftershocks in New Zealand since 12am on Sunday when an initial 7.8 earthquake centred north of Christchurch struck, causing extensive destruction, killed two people and triggered a tsunami up to five metres high.
The initial tremor created fractures in major roadways, brought buildings to the ground and forced frightened kiwis to flock to their local supermarkets to stock up on food, drinks and essential supplies.
It comes as authorities warn the worst of the major tremors may not yet be over.
New Zealand earthquake monitoring group GeoNet says there's a 12 per cent chance the country will be shaken by another quake of a 7.0 magnitude or higher before midnight on Monday.
Also worrying for residents is the fact that the Clarence River, one of the largest in the country, has burst its banks causing a huge 'wall of water' to rush towards homes.

A strong 6.2-magnitude earthquake hit northwestern Argentina Sunday, the US Geological Survey said, but there were no immediate reports of damage or injuries.
The quake, at a depth of 62 miles (100 kilometers), struck shortly after 1400 GMT about 16 miles north of the city Chilecito in the South American nation's La Rioja province.
Villagers reported that the movement was felt in the neighboring provinces of Catamarca, Tucuman and Cordoba.
The country's seismic authority also reported three smaller earthquakes Sunday.
The quake near the border with Chile follows a 6.4-magnitude earthquake of "great intensity" earlier this month in central Chile.
That earthquake shook buildings in the capital Santiago, causing panic among residents, whose frantic phone calls clogged cellular networks and land lines, AFP correspondents said.
