Hearing his partner on the telephone Joseph Albert Wharehinga angrily accused her of talking to another man before approaching her with a carving knife and stabbing it into a wall less than a metre from her head.
Pleading guilty to two charges of breaching a protection order at an earlier court appearance, the 47-year-old was back in Masterton District Court on Tuesday before Judge John Bergseng for a disputed summary of facts hearing.
However, his lawyer Ian Hard said Wharehinga accepted the police summary so his partner wouldn't have to give evidence.
Mr Hard said his client had been in prison for a month now and asked a short sentence of imprisonment be imposed.
"He has not done this in an easy way. He has found it very hard ... he wants to repair his relationship," he said.
