Her case comes as Wellington Police also work to find a 12-year-old girl reported missing on Saturday night.

The girl, named only as Liberty, was last seen at home about 8.45pm. She was wearing a black hooded jersey.

It was earlier reported that she was with a 14-year-old girl.

However, the other teenager has since been found safe and well.

Anyone with information is urged to call police immediately.
