The statement further claimed police had not indicated any action would be taken against the company or the driver.
“Our thoughts are with them and their friends and whānau,” the bus company manager said.
A police spokeswoman said the Serious Crash Unit was investigating to determine the circumstances of the collision and it was too early in the inquiry to make any further comment.
Motorists were earlier warned to delay their journey or avoid Gillies Ave completely after the crash between Alpers Ave and Owens Rd. Gillies Ave forms part of a major route to the airport. The road was reported re-opened by 11am.
Auckland Transport earlier said southbound lanes were closed between SH1 interchange and Owens Rd.
The traffic agency said northbound lanes remain open, but significant congestion is occurring in the area.
Police said a pedestrian was seriously hurt in the crash and a section of both roads would be closed while the scene was examined.
“Motorists are advised to expect delays and to choose an alternate route where available. The Serious Crash Unit is in attendance,” police said.
