“Police and whānau hold grave concerns for Te Anihana’s safety and urge anyone who sees her to call 111 immediately,” a spokesperson said.
Police and Pomana’s family made an appeal for information earlier in September.
Flyers were also distributed to local businesses.
Detective Senior Sergeant Martin Friend said at the time there was nothing to suggest 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.”
Friend said with such vast networks of CCTV in Auckland city, it was surprising Pomana had not been seen on CCTV after leaving SkyCity hotel.
Pomana’s mother, Catherine Anderson, made a plea for her daughter to make contact.
“Te Anihana is a much-loved daughter, aunty, sister, friend and mokopuna,” she said, “As a mother, I’m appealing 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.”
