Teachers and students from a Whanganui school were left stunned after a bus collided with two cars and rolled up a nearby grass bank.

Whanganui High School principal Martin McAllen posted about the incident on the school’s Facebook page.

“This afternoon we had a bus incident outside our bus bay at 3.10pm as students were finishing school for the day and heading home,” he said.

“The Brunswick bus pulled out of the bus bay area and hit a car travelling along Purnell Street.

“The bus then proceeded to hit another car (with no-one inside the car) parked on the other side of Purnell Street and accelerated up the driveway of a house on the opposite side of the road; the first car (with a driver inside) spun into our green wooden fence opposite the school library.

“It is extremely fortunate that no students or adults were hit by the bus or car at any stage of the incident.

“Police Officers, Tranzit group bus representatives, a first responder and an ambulance quickly arrived on the scene and the road was blocked from traffic at both ends of our school on Purnell Street while initial assessments were carried out.”

Several parents of students from the school commented on Facebook, expressing their shock over the incident.

“My son witnessed it all, golly students be shook after that”.

Police said officers attended a two-vehicle crash involving a bus and a car on Purnell St about 3.15pm.

“There were no serious injuries. Police are making inquiries.”
