A trailbiker riding on a footpath allegedly ran over an elderly dog being walked on leash.

Information on a motorbike rider who allegedly ran over an elderly dog on a footpath is being sought by police.

A Kāpiti Coast woman says she was walking her 11-year-old dog Tinker on April 7 when the man on a trail bike rode up behind them on the path near Kiwi Rd, Raumati. Her husband began filming the rider because he had seen him use the path before and vehicles were forbidden from using it.

The woman says she tried to move Tinker off the path but the man rode right over the dog.

Supplied A man riding his motorbike on a shared path allegedly ran over an elderly dog being walked by its owners.

"You could see the tyre mark on him where he went straight over him."

The moments before and after the crash were caught on camera and show the woman screaming and the rider falling off his bike before climbing back on and riding away.

Supplied Tinker, 11, was allegedly run over by a man riding a trailbike on a footpath.

"I was screaming at him and Tinker was yelping in pain."

Tinker was taken to the vet and treated for shock. He suffered bruising and scrapes on his groin.

He had been for a walk since and was scared of traffic noises, something that had never worried him before, his owner said.

Witnesses to the incident also took photos of the rider.

The biker was not only flouting lockdown laws but using a path for cyclists and pedestrians.

A police spokesman said on Sunday enquiries were still ongoing into the incident and asked anyone who might have information to contact police by calling 105.

Kāpiti Coast Mayor K Gurunathan described the man as a "community idiot" and urged police to "throw the book at him".
