"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."
