The Ministry of Health says it's appalled after a video of a baby being fed an alcoholic RTD drink has circulated on social media.
In the video, sent to Newshub, a baby lying on a couch has a Long White vodka drink poured into its mouth.
One person feeds the baby the alcoholic drink while another sits beside the child.
The person holding the bottle is wearing a wristband from the One Love festival.
"We are appalled to hear that there is a video circulating on social media of a baby being given an alcoholic drink," said Ministry of Health deputy director of public health Dr Harriette Carr.
"The ministry does not recommend babies or children be given alcoholic drinks.
"Alcohol has been shown to be harmful for the unborn child, babies, and children, particularly affecting brain development," Dr Carr told Newshub.
A police spokesperson said, at this stage, the incident has not been reported.
"Based on the information available from the video, it is not possible to confirm if a criminal offence has taken place," the spokesperson told Newshub.
"If indeed alcohol has been given to a baby, we would concur with our Ministry of Health colleagues who have described such behaviour as appalling."
A second photo has since emerged of the man, believed to be in the original video, appearing to give a baby a sip of beer.
The photo was captioned, "Her first Xmas eve and beer... #bestdadever".
Plunket and the Children's Commissioner have been contacted for comment.
