Appearing at Manukau district court, Auckland, the 42-year-old stood quietly in the dock, wearing a light beige hooded jacket, before being remanded into custody without entering a plea.
She had arrived in New Zealand on Tuesday after being extradited by South Korean authorities, who said they had handed over “significant pieces of evidence” along with the suspect.
The woman’s identity will remain secret, at least until her next court appearance, which is scheduled for 14 December. She and the children are both covered by strict interim suppression orders preventing the publication of their names and some identifying details.
In court on Wednesday, she requested, via an interpreter, to speak to the judge but her lawyer intervened, saying: “Thank you, Your Honour. I think it would be best if perhaps she didn’t.” Judge Gus Andrēe Wiltens responded: “I agree.”
