Southern District Police say the woman who was last seen leaving Riverton has been found "safe and well".

Police posted on their Facebook account earlier today that Mariana Teuila Isara had been reported missing after she failed to board a bus from Invercargill to Christchurch on Friday and they had concerns for her wellbeing.

In an update this evening, Police say the woman reported missing from Riverton Holiday Park has been found safe and well.

"Police would like to thank members of the public for their concern and for the information provided to Police," the post says.
