Police say their focus is on Tom Phillips' three children - after the latest sighting of what's believed to be Marokopa father and one of his kids

They've released CCTV footage of a shop burglary in the King Country town of Piopio early on Wednesday - showing two people wearing masks riding in and out on a quad bike.

Detective Senior Sergeant Andy Saunders says finding the family will take as long as it takes - and they're not going to get into a confrontation.

He says they have concerns about the risk Phillips poses - and have a message for him.

Saunders says it's the same as it's always been - to both him, and anyone helping him - let's get those children out safely.
