The trial of a Masterton man charged with sexually violating his wife started in Wellington District Court on Monday.
The man is facing three charges, sexual violation by unlawful sexual connection, assault with intent to commit sexual violation, and assault.
The offending was said to have occurred in May 2012, in Masterton.
Crown prosecutor Sally Carter said that on May 11, 2012, a physical confrontation between the man and woman took place and he assaulted her. Two days he assaulted her again, this time in the bedroom.
On May 13, said Ms Carter, the woman had returned home, after shopping with the couple's son, and went into the bedroom.
