Oranga Tamariki says it is "very concerned" that a video has surfaced online claiming a caregiver had dropped off a boy at a gang pad to scare him.
The two-and-a-half minute video, posted by a man to his Facebook page, has been viewed more than 10,000 times but had since been removed.
Alison McDonald, Oranga Tamariki's deputy chief executive, said: "We are very concerned that this video identifies the boy, and mentions various names and locations openly in the recording."
She said sharing the video widely on social media breaches privacy and could pose harm to a number of people.
"The person who posted the original video has removed it and has offered an apology," McDonald said.
