The mother of missing woman Rae Portman has made an emotional appeal for information about her daughter's disappearance.
The 33-year-old Auckland woman, was reported missing on July 2 and has not been seen since the end of June.
Earlier police extended their search for Ms Portman to the Bay of Plenty, after she was seen in Waihi and Tauranga in June.
At a media conference today, Rebecca Norton revealed her daughter was four months pregnant when she vanished.
Ms Portman has not been seen since June 20, when she travelled to Auckland and checked in at a Mt Albert motel.
Detective Inspector Mark Gutry said police had spoken to most of the people known to have seen Ms Portman that day.
"The last place we know she was seen was at the motel. We've been there and found her belongings,'' he said.
"But after we know she left the motel, we just don't know where she went. She failed to check out.''
Ms Portman, also known as Bok, was a known drug user and it emerged that she had been assaulted at a Manurewa property on June 8.
A 30-year-old woman has been charged in relation to the incident but police said it was not connected to her disappearance.
Mr Gutry said anyone with information about Ms Portman's whereabouts or disappearance should contact police or phone the hotline 0800 RAEPORTMAN.
