Three people were critically injured in two road crashes in the North Island last night.
Police central communications acting shift commander Mark Oliver said the first crash happened about 6pm in Awakino in south Waikato.
At least six people were injured, two critically and one seriously, when a silver Nissan saloon and a red Holden commodore crashed on State Highway 3, Mr Oliver said.
Three people suffered moderate injuries.
Of the three rescue helicopters which attended, two flew people to Waikato Hospital, he said.
