Meanwhile, 17 children, including a 6-year-old girl from Houston, were rescued.
During the sentencing at Christchurch District Court, Webb admitted an interest in girls over the age of 3, preferring images of girls aged 6 to 6, Christchurch Court News reported.
Those arrested overseas included caregivers, parents, and a kindergarten teacher, who had traded child sexual abuse images with Webb.
It was revealed Webb had pretended to have access to a daughter whom he could abuse to encourage others to abuse children and send him objectionable material as part of an arranged swap.
The charges were brought by the Department, NZ Police and NZ Customs after separate investigations.
Internal Affairs' Community Safety Manager, Steve O'Brien, said the crimes involved real children forced into degrading acts.
"It is important for our community to remember that. The children who are featured in objectionable images are themselves victims, coerced into participating in photographs and films by sick and dangerous people.
"Trading or viewing these images is not passive offending because it condones the abuse children suffer. People, who look at this, pass it on and use it, encourage those who actually photograph the children."
