NZ's Next Top Model finalist Rosanagh Wypych has said posting pictures online of alcohol and drug use had "jeopardised" her place in the competition.
The 17-year-old Hawkes Bay model posted the pictures on her Facebook page, making them accessible to her 3800 Facebook friends and anyone with a mutual friend.
Some of the pictures show Rosanagh with friends who were drinking alcohol, while one photo shows her looking on while another girl holds what appears to be cannabis.
One user posted: "great look for a top model", to which she replied: "not me smoking it".
TV3 said it would not comment on a private Facebook page, the New Zealand Herald reports.
But Mediaworks spokeswoman Rachel Lorimer said the network "takes its responsibilities towards younger viewers seriously" and did not condone illegal behaviour.
Rosanagh has come under fire earlier in the competition for not disclosing convictions for driving while disqualified and giving false details to police.
The final of Next Top Model will screen live on Friday.
