Emergency services are attending a crash between a truck and car on Hakarimata Rd in Huntly.
Waikato District Command Centre senior sergeant Will Loughrin said the crash happened just before 2pm today and firefighters were working on freeing a person trapped in the vehicle.
It was unknown how many people were involved in the crash at this stage.
A St John spokeswoman confirmed it had treated one person in a moderate condition who was being transported by ambulance to Waikato Hospital.
More to come.
