Footage from a small North Island town store is the first confirmed sighting of Tom Phillips in a year, nearly four years after he disappeared with his three children

New CCTV footage believed to show New Zealand fugitive Tom Phillips and one of his children allegedly breaking into and stealing from a convenience store has been released by police.

Detective senior sergeant Andy Saunders told media on Friday that investigators believe the pair in the video are Phillips and one of his three children, who vanished almost four years ago. It is the first confirmed sighting of Phillips in a year.

The footage, captured in the early hours of Wednesday at Piopio Superette, a small store in the North Island, shows a masked man and child examining windows before sparks fly as they appear to cut their way in with a power tool. They then load groceries on to a quad bike and drive away.

Saunders said the pair spent 13 minutes at the scene.
