A man punched his mother-in-law in the back of the head up to five times after flooring her with a punch to the face.
Jahvarn Vaughn Iremonger and his partner woke their two young children up early one morning when they were arguing. Iremonger's mother-in-law intervened.
He took exception to her interference, lashing out with his right hand and striking her on the left cheek.
Iremonger pleaded guilty to a charge of male assaults female in Whanganui District Court where he appeared for sentencing before Judge Garry Barkle.
"The victim was required to reside at your address because she was on electronically monitored bail," Judge Barkle said.
