One person has been critically injured in a crash that closed State Highway 2 through the Karangahake Gorge.
The two-vehicle crash happened near School Rd and was reported just before 1pm, a police spokesperson said.
The road has since reopened. Motorists have been warned to expect delays until congestion has cleared.
A Hato Hone St John spokesperson said four ambulances, one helicopter and one operations manager were sent to the scene.
“One patient, in a critical condition, is being airlifted to Waikato Hospital.
“Two patients, in a moderate condition, were transported to Waikato Hospital by road.
“Two patients were assessed and treated at the scene, no transport required.”
In a highway alert this afternoon, New Zealand Transport Agency Waka Kotahi said “K-Gorge is closed between School Rd, Karangahake and Waitawheta Rd, Waikino.
“SH2 is closed to through-traffic between Paeroa and Waihī.”
Motorists were advised to delay their journeys or consider using an alternative route.
Emergency services have been called to the crash.
More to come.
