The holiday road toll has climbed to 16 after a passenger injured in a crash on Boxing Day died in hospital this morning.
A Ministry of Transport spokeswoman confirmed this afternoon that the person died in hospital this morning from injuries sustained in the crash in Raglan.
Yesterday, Anthony Clifford Sparrow, 50, of Ashburton, died when his motorbike left the road on State Highway 73, near Dry Stream on Porters Pass, at about 5.45pm.
The two deaths have brought the holiday road toll to 16 - more than double the toll over last year's Christmas-New Year period.
The official holiday road period started at 4pm on Christmas Eve, and runs until 6am tomorrow.
