Lying dead between tyre tracks, it seemed obvious what had killed the little blue penguin found dead on Uretiti Beach.
It was an assumption that prompted Annette Laird to send the images to the Northern Advocate - one of two little blue penguins, or kororā, she had found dead on the beach.
"There's a lot of vehicles on the beach," she said. "People running their dogs from vans, hooning around in motorbikes and quads.
"The beach isn't the place for vehicles. We've got roads."
Laird, who is camping at the beach, said she wanted to see all vehicle use on the beach banned.
