On Friday, Kathy Yu-Jen Stephens, who is also a former cake retailer, was sentenced by Judge Nevin Dawson at the Auckland District Court. At trial Stephens told the court she was quite a "gullible person" and thought she was helping out a friend. Six days later, police searched a room at the Avani Metropolis Hotel where the pair had been staying and found 16 items of stolen Trelise Cooper-branded clothing. At a Bush's sentencing, the court heard how the burglary has had a lasting effect and "massive reputational damage" for Cooper.
