Earlier story

A 4.1 aftershock has rattled Christchurch this morning and caused the evacuation of Clifton Hill and Redcliffs because of worries due to cracks appearing in rocks and boulders above them.

Police haven’t confirmed the number of properties affected and earlier this morning police closed the main road into Sumner to assess the stability of rocks in the suburb.

The weather in Christchurch today is dry with high cloud and temperatures are expected to be in the low 20s.
