Bus operator Kinetic said its buses are designed and built safely, following questions by a union after the fatal crash in Auckland two weeks ago.
A diesel car caught fire after it collided with an electric bus, and the fire quickly spread to the bus.
The driver Sean James Cleary died as a result.
Tramways and Public Transport Employees Union president Gary Froggart earlier said they were worried about how easily the fibreglass at the front of the bus crumpled - trapping the driver.
Froggart said his concerns were not to do with the vehicle being electric, but related more to the structure of the bus.
Kinetic said in a statement that all of their buses were designed to provide a high degree of safety.
"All our buses, including battery-electric buses, meet Waka Kotahi New Zealand Transport Authority (NZTA) certification standards and are maintained to strict safety requirements," it said.
"Buses are built on a heavy chassis, designed to provide a high degree of safety for those on board," said its managing director in New Zealand, Calum Haslop.
The company said it had given bereavement leave to some staff to attend the driver's funeral this week.
While earlier, the Tramways Union raised concerns that some union delegates had been declined bereavement leave to attend Cleary's funeral this Thursday, Kinetic said they had signed off bereavement leave for some staff.
"The loss of our colleague is deeply felt across our team, and we are continuing to support one another. While the family has arranged a private funeral, they have invited those closest to the driver to attend.
"We have made arrangements for them to do so, and this will be recorded as bereavement leave. For other colleagues who wish to pay their respects, the funeral will be livestreamed with the family's permission," Haslop said.
Police said the investigation was ongoing and no charges had been laid yet.
