A large scrub fire has broken out in the Christchurch suburb of Ferrymead this afternoon closing parts of Tunnel Road, State Highway 74.
According to Fire and Emergency New Zealand, the highway has since reopened after a blaze burned through an estimated six hectares of native reserve beside the Heathcote River, causing significant damage to the saltwater marshes.
A Fire and Emergency spokesperson says the fire is yet to be fully extinguished but is contained.
Six fire engines, two tankers and two helicopters attended the blaze. Crews will remain at the scene overnight to monitor for hotspots and flare ups.
