The appeal comes after a High Court judge declined the woman’s application for continued name suppression in March.
Most of the hearing cannot be reported because of existing suppression orders.
The court reserved its decision this morning.
Last Wednesday, the defendant spoke up at the end of a brief court hearing to proclaim her innocence. “I didn’t do it, it’s the truth,” she said, raising her hand to address the court moments before she was led away by security officers.
The 42-year-old has been in custody since she was extradited from South Korea to New Zealand late last year after the discovery of her children’s remains.
An Auckland family made the grisly find after opening suitcases they bought in an auction for an abandoned South Auckland storage unit.
Police said the children would have been between 5 and 10 when they died and had been dead for years when their remains were found.
The defendant was born in Korea, became a New Zealand citizen after moving here, and likely returned to Korea in 2018, according to Immigration records.
She has pleaded not guilty and is set to face trial in April 2024.
