A 16-year-old Wairarapa boy originally charged with raping two girls, aged 12 and 14, now faces alternative charges.
The boy, who can't be identified for legal reasons, was charged with rape, then unlawful sexual connection and is now charged with two counts of indecent assault.
He previously admitted to having sex with the girls in a local park but said it was consensual. He has entered non-denial pleas to the charges.
In Youth Court on Thursday, Crown prosecutor Geraldine Kelly said there were concerns about the teen's underlying thought processes on sex and relationships.
She said he used guilt-like behaviour to isolate the 12-year-old victim and have sex with her.
