Police have appealed for help to find a missing Chinese teenager who has been in the country only a couple of years and speaks limited English.
Sixteen-year-old Chunji Gao, also known as Gary, has not been seen since leaving his home in suburban Botany on April 16.
Police said he probably did not take any clothing, possessions, or his wallet.
He had been reported missing before but had returned home or had been found within a couple of days.
Sergeant Brett Meale said he spoke limited English and had few friends in New Zealand after arriving a couple of years ago.
He said the boy's school had concerns he would not survive by himself.
When last seen he was wearing blue track pants, a dark coloured sports jacket and black and yellow shoes.
