The treatment of two teenagers left stranded after one of them was sick on an Intercity bus has left a Tauranga mother furious.

A driver of an Intercity bus left two 16-year-olds in Willow Street on last week in what the company says was a 'miscommunication”.

Tania Irvine, posted a scathing comment on InterCity's public Facebook page, saying her son had asked to get off simply to get some clean clothes out of his luggage after he was sick.

"The driver said no worries and pulled over, told the kids that he would be there in a minute to open the locker.

"They stepped off, leaving all their stuff on the bus – phones, wallets, everything – the bus driver then shut the door and drove off. Leaving two 16-year-olds in the rain at the side of the road with nothing."

InterCity general manager Sam Peate says on Wednesday that the incident was a result of a miscommunication between the teenagers and the driver.

"They got off and he saw them walk away and he carried on, but it appears [the teens] had an expectation they would get back on."

Close to 1000 people have shared Tania's post, and multiple people have posted on InterCity's Facebook page, claiming they will boycott the service as a result.

Sam says both teens were refunded their fares and given free tickets to the next available service, which took them to Wellington, via Taupo.

Tania's post went on to say: "We finally got hold of InterCity to be told we would get a full refund and they had been transferred to the later bus at 9.10am and that their luggage and personal items would be waiting for them in Taupo.

"So we thought all good, got them home, change of clothes and put them on the next bus."

The luggage was not waiting for them in Taupo. They were instead reunited with their bags in Wellington.

Her son's soiled jumper and baseball cap had been thrown away, she says.

'How dare you do that. This is theft. They did not abandon them these items, they were taken from them when the bus driver left them on the side of the road and took off.”

InterCity confirmed some soiled items on the bus were thrown away when the bus was cleaned.

Sam says he had been speaking to Tania, and InterCity had apologised, offered to replace her son's clothes and issued him with travel vouchers.

"There are definitely some things we have learned from this. There was that miscommunication,” says Sam.

"We really want to make sure we are clearer in future. If people get off the bus, do they want to get back on?"

In regard to any disciplinary action being taken against the driver, Sam says: "I can't comment on that for confidentiality reasons, but this is something we take seriously."
