A major provider for buses in Auckland has confirmed one of its drivers died in a serious crash overnight.
The driver died after their electric bus collided with a car on Tamaki Drive at around 9pm on Wednesday.
The managing director for bus operator Kinetic, Calum Haslop said his thoughts were with the driver's family, friends and colleagues.
He said Kinetic was working with authorities who were investigating the incident.
A spokesperson for Fire and Emergency confirmed the fire started in the car's engine.
"A fire started in the engine of the petrol vehicle, which then spread to the bus," they said.
"We are unable to provide any further comments at this stage, as investigations into the incident are ongoing."
Haslop said the batteries in the bus were undamaged and didn't contribute to the blaze.
Earlier, the union for public transport staff said the person who died in the crash was the bus driver.
A key Auckland road was also closed after the fiery crash involving one of the city's electric buses.
The incident led to a major emergency response.

AT said on Thursday Tamaki Drive remained closed between Ngapipi Road and The Strand.
The stretch of road was likely to stay shut during the morning, and AT warned of what would likely be heavy congestion.
"We will work closely with our operator, NZ police and Fire and Emergency NZ to understand what has happened and provide whatever support is needed," AT's public transport director Stacey van der Putten said.
AT said protest action would add to the congestion.
