The 26-year-old property manager also had to fork out $14,903 to pay for the light pole.
Chen was charged with dangerous driving and drink-driving, which he originally entered not-guilty pleas to.
But today the drink-driving charge was dropped and Chen admitted the other matter.
Judge Grant Fraser fined him $750, made him pay $130 court costs and disqualified him for nine months.
The judge noted the hefty cost of the crash. "Sadly that's the consequence of bad driving."
On the night in question Chen had been dining at The Chancery, Miss Harding said.
He was remorseful for his actions and had already paid Auckland Transport for the pole.
"[He] accepts that he could have lost his life or hurt somebody else and he's not going to do that again. He realises he needs to be very careful in a motor vehicle and regrets the error of judgment which has obviously had some severe financial consequences."
He was in New Zealand on a tourist visa, which had to be extended because of the prosecution.
Away from court, Miss Harding said the drink-driving charge was withdrawn because police did not follow correct procedures. Chen was not offered the chance to have a blood test, nor was he given access to a Mandarin interpreter.
