Professor Sally Casswell of the SHORE & Whariki Research Centre at Massey University said children were "quite clever observers" and the survey's findings were interesting when compared with other developed nations.
"In terms of the survey findings the comparison I would look particularly at is the comparison with the other developed countries and in both the cases the children were more likely to say in New Zealand that alcohol and drugs were the main causes of violence," she said
"I think this reflects the fairly high level of consumption we have in New Zealand."
The survey showed 13 per cent of New Zealand children blamed domestic abuse as the main cause of violence, which was higher than other developed countries.
"It's not such a big difference ... but it is there," said Professor Casswell.
