More than two dozen New Zealand children have been exploited for online pornography in the last four years, with some of the material traded through criminal networks.
Figures obtained by Radio New Zealand showed since 2008, a special police unit had caught 11 people taking pictures or videos of 26 children.
The figures, released under the Official Information Act, revealed four of the children were exploited by criminals based in Italy, the United States, Finland and Canada where images of the victims were uncovered during international operations, RNZ reported.
The head of the police online child exploitation unit, Detective Senior Sergeant John Michael, said in some cases offenders were working in crime rings.
"(But) while there are rings there, you have individuals that are not part of any group that are able to go to those areas of the internet where they know they'll be able to get images."
