A Chinese tourist thought he could overtake on blind corners because there were no yellow lines, and didn't know to stop for police using flashing lights, a court has heard.

Zhiang Ding, 29, of Chongqing in southwest China, was one of four tourists - including one whose keys were removed from his rental vehicle by a member of public - to appear before Judge Christina Cook in Queenstown District Court this morning.

Ding was fined $1000 and disqualified for six months for dangerous driving on State Highway 6 on Sunday.

A member of the public called police when Ding repeatedly crossed the centre line and tried overtaking on blind corners, in Garston, at Athol, Kingston and along the Devil's Staircase.

He reached a speed of 134kmh and failed to stop for police using flashing lights. He was eventually stopped when he reached a traffic queue at Frankton, the court heard.

Lawyer Sonia Vidal said Ding believed overtaking was permitted anywhere if there were no yellow lines and he claimed he did not know flashing police lights meant he should stop.

Judge Cook said she was concerned Ding continued crossing double-yellow lines on the Devils staircase, a stretch of road with multiple blind corners.

"This is a prolonged piece of dangerous driving," she said.

"Whatever the practice is in China, it's common sense you would not overtake a vehicle on a corner where you cannot see the other cars. You should not be driving the roads in New Zealand if you are not familiar or competent to drive in a safe way."

Chinese citizens Yusi Yang, 30, of Chongqing, and Qian Li, 34, of Hangzhou in eastern China, and Indian national Pratik Shah, 24, of Mumbai, also appeared in court.

OVERTOOK SIX CARS ON BLIND CORNER

Yang, a Communist Party member, was fined $900 and disqualified for seven months for dangerous driving on the Cardrona Valley Rd, also on Sunday.

He was in a queue of traffic approaching the Cardrona ski field turnoff, pulled out and overtook six cars on double yellow lines while approaching a blind corner.

He stopped after the manoeuvre and a member of the public also stopped and removed the keys from Yang's rental car.

Lawyer Liam Collins said Yang had read the New Zealand road code before going on honeymoon. During the manoeuvre other vehicles had failed to allow Yang back into the left lane, he said.

VEERED ONTO RIGHT-HAND SIDE

This afternoon, Qian Li admitted three counts of careless driving causing injury in the crash at Gibbston, near Queenstown, on Saturday, when she appeared before Judge Christina Cook in Queenstown District Court.

Two British tourists in the oncoming car were seriously injured.

Sergeant Rob Mills said Li and her friend Mingyue Shen were driving from Glenorchy to Cromwell when she crossed the centre line near the AJ Hackett bungy bridge on a busy Saturday afternoon.

Road conditions were dry and fine with heavy traffic, he said.

Li veered suddenly into the right-hand lane and crashed head-on into a Toyota Corolla rental.

Shen, suffered minor injuries while two British visitors were airlifted to Southland Hospital and Dunedin Hospital. They required surgery and remained in hospital.

"At the crash scene she said she was on the wrong side of the road. After speaking to a lawyer she declined to comment any further," Mills said.

Li was due to return to China on Friday but she was remanded on bail for sentence on March 9, ordered to surrender her passport and ordered not to drive. Judge Cook also asked for pre-sentence reports, victim impact reports and referred the case for restorative justice.

DANGEROUS OVERTAKING BY HONEYMOONER

Shah, on honeymoon in New Zealand, was fined $750 and disqualified for six months for dangerous driving on the Te Anau-Mossburn Rd, on Sunday.

He overtook a tourist bus returning from Milford Sound on a straight but failed to see an oncoming car, forcing the bus to brake hard and the oncoming car to take evasive action.

Sergeant Rob Mills said a bus-load of 16 American tourists were adamant it was a very close call and Shah appeared to have no appreciation of the potential consequences.

Brazilian national Juliana Oliveira Machado, 28, of Fernhill, also appeared charged with dangerous driving after an incident on her first day behind the wheel in New Zealand.

She was fined $700 and disqualified for six months for dangerous driving on Coronet Peak Rd, on December 16.

She drove on the wrong side of the road and an oncoming vehicle and Machado were forced to stop to avoid a crash, the court heard. She told police she thought she was driving slowly to be safe and she had no explanation for driving on the wrong side.
