Police are investigating whether Chester Borrows ran over a protester's foot in Whanganui.

The incident is believed to have happened when protesters were blocking the driveway of the Collegiate Inn in Whanganui's Liverpool Street yesterday.

Climate Change Minister Paula Bennett was also in the car which had been surrounded by protesters.

Police were trying to remove protesters so Mr Borrows and Mrs Bennett could leave the venue.

Mr Borrows said he was not aware that he had run over anyone's foot and believed the police had pulled the protesters clear.

“I was inching forward, they were taken out of the road, and I didn’t drive until the road was clear.

“I had no idea that anything had happened and I am pleased to see that the woman doesn’t have any broken bones or anything like that.”

He added: “Everyone’s got a right to protest, I don’t have an issue with that at all. I’m just pleased that the lady is not hurt.”

The MP said he later saw a post about the incident on Facebook, after which he called the police.

They had not contacted him again yet, but he expected to hear from him.

“I am quite happy to talk to the police and to tell them what happened,” he said.

The Prime Minister's aware of the incident but doesn't appear to be too concerned.

John Key said he understands the car was moving very slowly and was simply trying to move out.

Mr Key said Mr Borrows is a very gentle person and isn't the sort who goes seeking controversy or getting angry.

Protester Tracy Treadwell was taken to hospital by St John Ambulance.
