The Department of Conservation is investigating concerns over a jet ski driving through a pod of dolphins after a video of the incident emerged on Instagram.
The video, which was posted on Instagram by Auckland real estate mogul Ricky Cave on Sunday, shows a jet ski travelling around 22km/h as dolphins swim around it.
A member of the public contacted DoC and the Herald raising concerns about the Cave's actions and the safety of the dolphins after seeing the video online.
The video was taken out from Pauanui in the Coromandel at the weekend, according to a source.
