Homes are being evacuated as a large fire rages on near Redcliffs.
Emergency services were called to the blaze on Galilee Lane at about 11.30am on Tuesday.
A police spokeswoman said firefighters are continuing to fight the fire which is currently around four to six hectares.
There are currently 4 helicopters assisting with firefighting efforts.
16 houses around Revelation Drive, Bay View Road and Galilee have been evacuated as a precaution.
A Fire and Emergency NZ spokeswoman said eight appliances, as well as water tankers, are in attendance at the large fire.
A command unit has been set up at the scene.
NewstalkZB radio host Chris Lynch is at the scene of the fire and said flames are dangerously close to homes.
"It is just metres away from houses on Clifton Terrace, you can see the flames which are metres in the air."
Witnesses are reporting high flames and heavy smoke with about 13 police cars and six to eight fire trucks attending the fire.
Redcliffs shop assistant Dylan said he's got a clear view of the fire which is about 1km away with a lot of flames.
He said it pretty crazy out there and the fire is roaring.
The latest blaze comes after the back of a spate of fires on the Port Hills the past week.
The fire is being fanned by a northeast sea breeze.
Clifton Terrace is closed at Main Rd, a Christchurch Transport Operations Centre spokesperson said further closures in the area are expected.
"Road users are advised to follow the directions of emergency services in the area."
Canterbury firefighters are warning those near the fire to keep inside and take action to prevent the smoke entering households.
Canterbury Fire and Emergency have posted on Facebook smoke can be seen and smelt around the surrounding areas.
"If you live near the area we advise you to close your windows and doors.
Please stay away from the scene to allow our crews to work safely to get the fire under control," read the post.
Police say thousands of people were affected by today's convoy.
