A man became so intoxicated he could not recall drawing a knife and waving it towards his partner of nine years while they were having an argument.
Ford William Berry and his partner travelled to Whanganui from Palmerston North on Saturday, November 3 for a family Guy Fawkes gathering.
The two went out socialising before attending the gathering, then at 2am the victim retired to the home where she was staying.
Berry later showed up at the address in a car with a friend and they drove around together for about an hour before he went inside.
Police prosecutor Stephen Butler said the couple began arguing in the lounge at 3am before Berry produced a small knife from his pocket and began waving it at his partner.
