New Zealanders are waking to what is being described as their darkest day as the death toll from the Christchurch earthquake could reach as high as 300 today.

Search and rescue teams were last night scouring the destruction in Christchurch in search of survivors, but the earthquake death toll is expected to rise as more bodies are found in the rubble.

At least 65 people, including children, have been confirmed dead   a number which Mayor Bob Parker said could double.

Last night, other reports put the death toll as high as 300.

Parker said 120 people were believed to have been pulled alive from the debris.
