An Inglewood High School spokesperson said earlier that all they knew was that there had been a crash involving a school bus.
She said police had informed them that they were bringing students back to the school.

Inglewood High School posted on Facebook saying, "Please be aware that the Egmont Village Bus has been involved in an accident.
"This is a developing scenario but as far as we are aware, no-one has been injured.
"We have been told that the police will be ferrying students back to Inglewood High School. This is all we know at present. We will keep you updated.
"Please refrain from coming down to the school. Thank you for your consideration and patience as we work through this unexpected situation."
Inglewood Primary School Board of Trustees chairman Grant Kenny posted on the school's Facebook page to tell parents that no Inglewood Primary School students were travelling on the bus.
"Our thoughts are with everyone at this time," he wrote.
It is third serious incident involving buses in the last fortnight.
Last Thursday 19 people were injured after the bus they were travelling in crashed into a ditch by State Highway 1 in the Manawatu.
Another bus crash on Mt Ruapehu killed 11-year-old girl Hannah Francis after the vehicle she was travelling in lost control and rolled near Tūroa skifield on July 28.
Both buses involved in the Manawatū ditch and Mt Ruapehu crashes were Mitsubishi Fuso models from the 1990s.
The group travelling through State Highway 1 in the Manawatū was carrying an iwi group that had travelled to Parliament to protest the Pare Hauraki Treaty settlement deed signing.
Police said then that six people were taken to Palmerston North Hospital with moderate injuries and 13 went to Whanganui Hospital with minor injuries.
The 1994 Mitsubishi Fuso bus that crashed and killed Francis had failed nine inspections between 2006 and 2016.
It has been reported that the bus' brakes failed before crashing into a bank and rolling.
