Chased by police with a child in a car seat on the petrol tank of his motorbike, Aki Henare gave his pursuers the "finger" and fled, reaching speeds of 70km/h in a residential street.
Appearing before Judge Peter Butler in Masterton District Court this week, the 24-year-old shearer pleaded guilty to dangerous driving and failing to stop for police.
Police prosecutor Garry Wilson said Henare was seen by police riding the motorbike at 65km/h with the child in a car seat perched on the petrol tank.
They tried to stop him but he sped off, Mr Wilson said.
"He gave police the finger."
Clocked driving at 70km/h on Cameron Cres, Henare went home and parked the motorbike in the garage.
Police arrived soon after.
"He said he was taking his son for a drive."
Defence lawyer Virginia Pearson said it was a ridiculous thing to do. Neither Henare nor the child were wearing a helmet.
"It was stupidity at the end of the day."
On the dangerous driving charge, Judge Butler disqualified Henare from driving for six months and fined him $900 and $130 court costs. On the failing to stop charge, he was sentenced to a further three months disqualification for a total of nine months.
