Fire fighters are battling to control a large scrub fire in West Melton - the latest in a spate of fires in Christchurch over the last 48 hours.
A total of 15 fire appliances and water tankers are battling the blaze which started just after 1pm on a property in Thomspons Rd, near the Waimakariri River.
Three helicopters are also using monsoon buckets to douse flames.
A Fire Service spokesman said the blaze is about 100m long but was unsure whether or not properties were in danger or if any evacuations were beginning to take place.
"I don't have a lot of information about it at the moment. But we may need more helicopters, we are not sure yet."
