Commander Kirsty Schofieldsaid the arrest highlights the AFP's close partnership with NZ Police.
"Australian and NZ Police stand together in protecting our young people from this abhorrent crime," Schofield said.
"It is disgusting that adults trawl online platforms to try to engage children in sexualised conversations or to send intimate images, and the distress and harm it causes children is irreparable.
"We work tirelessly with our partners to stamp out this behaviour and prosecute anyone who preys on children – whether that's online or through physical contact."
Schofield hopes the allegations would also remind families that cyber security is an important conversation to have.
"It is important that children feel comfortable talking to adults if they are worried about someone who has contacted them online and not share anything online that they would not tell anyone else about."
