Demolition of cliff-top homes begins
It will take four weeks to demolish a cluster of cliff-top homes destroyed by the earthquakes.
Work began before dusk this morning on the Clifton Hill demolition.
The demolition by a team from Southern Response, Canterbury Earthquake Recovery Authority (Cera) and Arrow International has been in planned for months.
The first cluster of demolitions will be mostly straightforward, but will allow access to more ''challenging'' properties, closer to the cliff edge.
The work was due to start last Monday, but wet weather delayed the team until this week.
At 5am today, heavy-duty excavators were moved up the hill.
The demolitions mark the first time Cera and an insurer have worked together to clear properties in the Port Hills residential red zone.
Demolition of the first cluster of properties is expected to take about 20 working days.
