She managed to get away from him, locking herself in the bathroom where she called 111.
She suffered swelling and soreness to her nose and mouth area, and was bleeding substantially from the nose. She was taken to Wanganui Hospital to be examined.
When police put the allegations to him, Fergusson said they were "b******t''.
Fergusson's counsel, Peter Brosnahan, said Fergusson and the victim were in contact and the only reason they were not back together was because of a non-association clause in his bail terms.
Judge Dugald Matheson called the incident an "unhappy situation'' which had caused considerable stress to Fergusson's living arrangements.
The victim had contacted the court saying she would like the relationship to continue, and would like to get on to counselling, but the bail condition was preventing that process.
She requested a protection order, which was granted. Part of the terms of the order require Fergusson to attend a stopping violence programme.
Judge Matheson explained to Fergusson the order did not mean that they could not reconcile, simply that if the victim started to struggle with his behaviour she could call the authorities.
