Cowie failed to stop for police and instead led them through city streets, accelerating heavily.
He often crossed onto the wrong side of the road, took blind corners at high speeds, and even pulled a couple of wheelies.
Police pursued Cowie for 5km before deciding it was too dangerous to continue as he sped away at 156kmh along Mornington Rd.
However, Cowie decided to hand himself in at the Dunedin Central Police Station early the next day.
He revealed himself as the rider of the motorbike and admitted he was speeding and that he had failed to stop.
"He stated that he made a snap decision when the patrol activated its red and blue lights, that it was stupid," court documents set out.
Cowie had said he saw what a danger he had posed to other road users and was remorseful.
He felt "an immense amount of shame", Mrs Turner said.
Judge Kevin Phillips said the driving was "absolutely reckless".
Cowie was fined $700 and disqualified for 14 months on one charge of dangerous driving and one of failing to stop for police.
