One person is in a critical condition and was being airlifted to Waikato Hospital following the two-vehicle crash on State Highway 2 south of Waihi earlier today.
The road remains closed and is likely to remain so for some time while repairs to the road are undertaken.
The person was freed from the wreckage of a head-on collision between a truck and a car in Waihi, Hauraki.
Fire and Emergency northern communications shift manager Craig Dally said the head-on crash was on State Highway 2 near Old Tauranga Rd.
