A charitable trust is 'extremely annoyed' an old photo of dead kiwi is being repurposed by anti-1080 campaigners.

In 2016, the Bay Bush Action Group posted an image on its Facebook page of around 50 dead kiwi that were killed in the Kerikeri region by dogs and cars.

The image has recently been used by other individuals and groups claiming the birds were killed by the pesticide 1080.

A post on the Facebook group "1080 Eyewitness Open" on Saturday which claimed the birds were poisoned by 1080 got more than 1000 shares before being deleted.
