A group of surfers - including a Kiwi - have arrived in the Indonesian city of Padang with a harrowing tale of survival in the tsunami.

A Kiwi was forced to jump into the sea when a 3m tsunami tore two boats from their anchorages at an Indonesian surf break.

Nine Australians feared missing after the Indonesian tsunami are safe and well.

Around 50 New Zealand surfers could have been in the Indonesian area where a small tsunami caused by a 7.7 earthquake hit early this morning.

Surfers on a charter boat jumped into the water when a three-metre high wave forced another boat into their craft, causing an explosion.

A star-studded line-up of Kiwi musicians will perform tomorrow in earthquake-hit Christchurch.

Some Christchurch residents don't know when their land will be fixed or how they'll live meantime.

The demolition of an earthquake-ravaged historic building has begun despite an outcry from heritage campaigners.

Aftershocks have continued this afternoon after a magnitude 5.0 quake hit late this morning, causing panic, power outages and damage.

Civil Defence say today's 5.0 aftershock would have felt on the ground like a magnitude 7 quake.

Demolition has begun on one of Christchurch's most famous buildings, Manchester Courts, which suffered irreversible damage during the massive September 4 earthquake.
