There were concerns for Mariana Teuila Isara after she failed to board a bus from Invercargill to Christchurch on Friday last week.
She was last seen leaving Riverton Holiday Park on foot about noon on Friday, police said.
In a post on social media tonight, Southern District Police said Ms Isara had been found and was well.
"Police would like to thank members of the public for their concern and for the information provided to police."
