An Oamaru man accused of offering his 13-month-old son for sexual gratification for $500 will appear in Oamaru District Court on Wednesday.
He faces 40 charges, including sexual violation, indecent assault, and making, distributing and possessing an objectionable publication.
His son, now 18 months, is in Child, Youth and Family care but is being looked after by his family.
The charges followed a North Island paedophile admitting a raft of horrific offences against children after New Zealand police infiltrated an international "spider web" of child abusers.
Aaron John Ellmers, 41, was arrested in Christchurch, and police say their intervention rescued four New Zealand children, ranging in age from 13 months to 13 years, from further abuse.
Ellmers appeared in the Hastings District Court last week and admitted multiple child sex offences that Crown lawyer Steve Manning described as among the country's worst.
One of the offences involved Ellmers offering $500 to the Oamaru father for "sexual gratification" with his 13-month-old son.
The Oamaru father, who cannot be named, had posted images of his son on a website. Ellmers, a Hastings truck driver, was arrested before he could offend against the toddler.
The father will appear in the Oamaru District Court on Wednesday, the court registrar confirmed on Friday.
A third man, 24, from Auckland, has admitted 20 charges of sharing and possessing images of child sexual abuse.
