The Nelson Marlborough Rescue Helicopter flew one person with serious injuries to Nelson Hospital. A St John Ambulance spokesman said one person with moderate injuries was taken to Wairau Hosptal in Blenheim by ambulance. Initially a diversion was in place for northbound traffic, and motorists were asked to avoid the area, and expect delays. Both lanes were reopened by 3pm. Waka Kotahi NZTA also issued a warning to motorists on Friday afternoon to drive carefully and plan trips in advance, as wet and windy conditions were forecast for the weekend.
