Peter Koziol left Palmerston North early Monday planning to fish the Waipawa River, before returning home.

He was last seen by the Waipawa bridge on State Highway 2 about midday that day with his vehicle, a blue Ford Falcon, ZG4508, which has since been recovered by the police.

Police would welcome any news of Mr Koziol, who's described as a bald Caucasian man who wears glasses.

He may have a blue backpack and full-body brown PVC waders on, police said.
