A Cobden man who evaded police by jumping into the Grey River after midnight on New Year's Day may face a hefty emergency services bill for his "crazy and diabolical actions".
The NZCC West Coast Rescue Helicopter combed the Grey River for about 40 minutes, searching for the 34-year-old before he was finally located on the Cobden Island, across the river from where he had jumped in, taunting the police who were on his tail.
Sergeant Matthew Frost, of Greymouth police, said the incident had unnecessarily taken up a lot of police, Coastguard and rescue helicopter time.
"This was a crazy and diabolical action, at great risk to himself and resulting in a huge amount of resources being called out," Mr Frost said.
He was unsure whether police would seek reparation for all the emergency services' time wasted but said they might.
