A court has heard how a Wanganui man developed "an interest" in incest and paedophilia and shared live videos of his children online.
The 39-year-old man, who has name suppression, pleaded not guilty in the Whanganui District Court yesterday to four charges of committing an indecent act on a child.
The court was told the man allegedly showed one of his young daughters another man's genitalia via webcam and later performed sexual acts as another daughter sat with him on his bed.
In his opening address, Crown Prosecutor Lance Rowe said the case was about a man who "developed an interest" in paedophilia and incest and used an online chat service to meet others and discuss their "shared interests".
Mr Rowe said the man chatted with a couple in Sydney who involved their 9-year-old son in their acts, and that Australian police found records of their interactions on the couple's computer following investigations into a child pornography ring.
