Christchurch police have "serious concerns" for a missing Chinese visitor who has not been seen since the weekend.
Ping Lyu, a visitor to New Zealand from China, was last seen on Stewart Street in the Christchurch suburb of Addington on Saturday.
Police said the 41-year-old has no known relatives in the country and does not speak English.
"Our main concern is that no one has seen or heard from her since Saturday afternoon, and she could be anywhere," police said.
"She is a recent arrival from China and it's possible she is travelling independently around the country, but we want to establish that she's safe.
"Anyone who has seen Ping, or who has information on her whereabouts, is asked to call police on 111 immediately and reference the file number 240525/9699."
