Tossing a litre of cold water over his partner helped land a Masterton man in hot water in Masterton District Court on Wednesday.
Hayden Oscar Polden, 25, unemployed, was convicted of assault on a female and sentenced to nine months' supervision.
He had pleaded guilty and was also ordered to attend a stopping violence course and to have drug and alcohol treatment.
Prosecutor Sergeant Garry Wilson said that on Boxing Day last year an argument had ensued between Polden and his partner over visitors to the house.
Polden had thrown a litre of cold water over the woman while she was seated and when she stood to confront him had slapped her on the cheek, then pushed her down on a sofa and held her by pinning her arms.
