The head of a social media agency says it is no surprise Facebook is using New Zealand as a testing ground for a new feature.
The BBC has reported Facebook has been trialling a service allowing users to set their posts, including photos, to delete after a scheduled time.
It said the feature was only being tested in New Zealand.
Vaughn Davis, who runs the Goat Farm in Auckland, said the country was a popular guinea pig for social networks trying out new ideas.
"It's sort of a microcosm of the developed Western world. You know, there's 2.5 million Facebook users, a high percentage of mobile users and we're all pretty active on the programme."
Mr Davis said Facebook users should be wary of so-called self-deleting posts, as people can still find ways to access them.
