A flood of "fake NZ news" pages are swamping social media with misleading slop, including using AI to animate still photos of a Mount Maunganui landslide victim.

Dodgy Facebook pages devoted to churning out AI-generated images and videos are almost unavoidable on the site now - and they're still fooling an awful lot of people.

In an investigation I conducted for the Australian Associated Press, a Facebook page calling itself "NZ News Hub" - which has no connection whatsoever to the now-defunct Newshub - has been pushing out dozens of posts a week that take the legitimate reporting by news organisations including RNZ, the New Zealand Herald, Stuff and others, and add sloppy AI-generated images or videos to them.

In one case, a video was posted that grotesquely animates a still photo of a 15-year-old Mount Maunganui landslide victim, making her appear to dance.

The page's bio proclaims "NZ News Hub brings you the latest New Zealand news, breaking stories, politics, business, sport, and community updates", but it does not appear to contain any original reporting.

For instance, on Waitangi Day, the page published a post that appeared to be a video of Prime Minister Christopher Luxon at Waitangi, but was clearly generated by AI.

Nevertheless, the page, which has nearly 5000 followers, has dozens of people "liking" and commenting on its posts as if they were real. Many of their followers appear to be business pages and even include a few politicians.
