With Xiao having pleaded guilty to a charge of dangerous driving causing death, which carries a maximum penalty of 10 years' imprisonment, Judge Mackintosh took into account the defendant's co-operation, early plea, remorse and previous good character, deducting just over two years from the three years and six months starting point suggested by Mr Manning, who said that in the search for precedent he looked at three cases of foreign-driver culpability in New Zealand road crashes, although, he said, there were "many" more.
About 15 members of Mr Middleton's family were in court, holding a framed photo of the man whose death they said had changed their lives for ever.
Father Michael and brother Ryan, who along with two others were riding with Rhys Middleton on the day of the crash, both provided victim impact statements which were read to the court, Michael's being narrated by police crash investigator Senior Constable Corey Ubels.
Mother Judy Richards steeled herself, muttering she had "to do this" and read her statement, as did son Ryan and "widow" Laura Settle, whom Rhys Middleton was to marry on February 11 next year - a day when, she said, celebration would be replaced by commemoration and a visit to the cemetery.
A letter of apology and remorse from Xiao was also read to the court by Napier homestay host Graham Hodder.
A police summary read to the court when Xiao pleaded guilty on May 4 says that a week before the tragedy, Xiao and a friend bought a Toyota Rav 4 ahead of their trip to Rotorua.
On February 6, they drove towards Waimarama and despite her friend's concerns about Xiao's driving they decided to make the trip the next day.
On the day of the crash, other motorists had been alarmed by her erratic driving, drifting to the left and over the "fog" line and speed chopping and changing between 70km/h and 100km/h, before she veered to the left one last time, fully off the road, crossing the entrance to an orchard before over-correcting sharply and collecting the machine ridden by Rhys Middleton as he was attempting to overtake her.
The bike was thrown into a fence and Rhys Middleton crashed to the ground, a passing motorist stopping and rushing to his aid, and brother Ryan turning and going back to carry out CPR, as he felt his brother's last signs of life disappear.
Their father rode on ahead, oblivious to what had happened until he received "the call" when he reached Taupo an hour later.
The ride back to the scene was the longest of his life, although it was a beautiful sunny day.
"It was just like today," he said, looking from a window to the mid-winter world awaiting the family struggling to overcome the impact of the tragedy.
