An elderly man accused of using teenage girls as "sex slaves" should know in a few weeks whether he will escape penalty.
He has reportedly developed mild dementia and may be found unfit to stand trial. Defence and Crown lawyers have each obtained psychiatric and psychologist reports.
The 79-year-old North Island man has not entered pleas to the 22 counts he faces, including abduction and multiple rapes.
First charged more than two years ago, he is seeking permanent name suppression. His next court appearance is set down for mid-June.
Suppression orders surround the case, which involves four complainants.
