A minibus carrying about 20 people has rolled in Waikato.
Police said the Intercity bus and trailer crashed on State Highway 29 near SH1, west of Cambridge.
About 20 people were on board but police said it appeared there were only minor injuries.
Ambulance staff called a helicopter to the scene to take two children to hospital as a precaution.
Bus operator Intercity has sent a replacement vehicle to complete the journey with passengers.
Police said the road was closed between SH1 and the intersection with Taotaoroa Rd, but the closure would not affect main arterial roads.
