Tougher fire restrictions for the scorched Canterbury region aren't expected to come into effect until later this week. This is despite a flurry of wildfires that have broken out throughout the region over the past few days. Fire crews have now contained a blaze that burnt through about 150 hectares near West Melton in the Selwyn district, forcing 50 homes to evacuate. It is one of at least four fires that crews are battling around the region, including the wildfire at Castle Hill that has been burning for five days. Reporter Adam Burns has more.
