One person is in a critical condition following a crash on State Highway 1 near Taupo, reports Stuff.
The injured person is understood to have been the driver of a car which hit a barrier south of Wairakei at approximately 4:15pm.
"The car is blocking traffic in both directions," a police spokeswoman told Stuff.
The road has been closed between Wairakei roundabout and Centennial Drive.
"Diversions are in place," added the spokeswoman, "but they are a long way from the crash site, so we're asking people to delay their travel."
