A massive fire at Pegasus Beach north of Christchurch continued to burn overnight and is covering an estimated 200ha, Fire and Emergency says.
Three helicopters and fresh crews will be mustering at first light and will be working to a plan to contain the fire and bring it under control.
About 50 firefighters and 12 fire trucks are on the scene in an attempt to control the blaze, and more than 100 people have been evacuated from their homes.
Fire and Emergency NZ (FENZ) Incident Controller Colin Russell said winds had dropped on the fireground in the last couple of hours, and crews had worked hard on the western flank of the fire to contain it overnight. Firefighters have also been carrying out structure protection at the camping ground and tackling spot fires.
