Lyons said the offending generally started with a direct message to the child victim on
social media.
The child was then asked to continue chatting on a different app, and the conversation often became highly sexualised.
From there the youngster was coerced into sharing intimate photos and videos of themselves, which were used to blackmail them, with threats to share it on their social media contacts list unless they pay.
In some instances, photos were doctored by the offender to make the child appear to be in even more compromising positions.
Police said the adult offenders also saved naked or sexual images of the young person during livestream or video calls which was often part of the extortion in a practice called capping.
"We are shining a light on this serious issue to ensure New Zealand young people, their parents and caregivers are aware of the risks and remain vigilant to ensure it does not happen to them," said Lyons.
"However, if it does, the best protection a victim has is to come forward and seek specialist support from Police as soon as possible. We will not criticise or blame you – what has happened is not your fault and we are here to help you."
