Police in Auckland are monitoring a New Zealand-based Asian website, SkyKiwi.com, in the hope that new information about a missing Chinese student turns up on it.
Jiayi Li, 18, also known as Kiko, was last seen on 19 May in the suburb of Kingsland.
Police say they have had a report of her red Toyota Altezza on Franklin Rd in Ponsonby six days afterwards, but there have been no confirmed sightings of Ms Li herself.
SkyKiwi chief editor Hewitt Wang says her disappearance is generating a lot of interest on the website, with more than 13,000 hits on a discussion thread.
Mr Wang says he understands the Chinese Consulate is trying to get in touch with Ms Li's parents in China.
Cellphone unused, bank account untouched
Police spokeswoman Noreen Hegarty says the missing woman had been studying at an institute in central Auckland and it's believed she had been living alone.
Her cellphone hasn't been used since she was last seen, she left her wallet at home in Sandringham and it appears her bank account has not been touched.
Ms Hegarty wants the public to call the police if they know anything that might help them find her.
Ms Li is 160 centimetres tall, of slim to medium build, with shoulder-length straight, dark brown hair and a skull-and-crossbones tattoo on her left forearm.
