Investigators traced the activity to a Nelson address, and the man, who cannot be named yet, was arrested and charged with causing digital harm, possession of objectionable material and child exploitation.
Detective Senior Sergeant Ciaran Sloan said this type of crime was extremely upsetting for those affected by it.
In the Nelson District Court today the man was remanded on bail without plea until June 20.
Judge Tony Zohrab imposed a set of strict bail conditions, including that he not access the internet except for work or to carry out banking, to not possess any device or item capable of taking digital images, and to not be in contact with any female under the age of 18.
The police advise anyone affected by this type of behaviour to report it.
