Family of a woman missing for more than two weeks have shared a new photo of her, a day after appealing for her to return home.

Te Anihana Pomana, 25, was last seen leaving Sky City about 5.06am on 21 August, leaving all her belongings at the hotel. CCTV footage showed her last known movements.

She was dressed in all white and Detective Senior Sergeant Martin Friend said she appeared to be "confused", before she disappeared.

On Friday, mother Catherine Anderson made a public plea for her daughter to come home.

"Te Anihana is a much-loved daughter, auntie, sister, friend and mokopuna," she said, "As a mother, I'm appealling to anyone who has seen her to come forward.

"Te Anihana, if you see this, we all love you and miss you, and want to know you're okay."

Detective Senior Sergeant Martin Friend said nothing suggested foul play, but the length of time Pomana had been missing and the fact she left all her possessions was worrying.

"We just do not know what's happened to her."

Pomana is of thin build, about 1.54m tall, with curly black hair and tattoos.
