The protection order was instated in 2017 when Smyth was convicted for male assaults female after attacking the same victim.
Lawyer Richard Leith said that Smyth and his partner had moved to a new address on the day of the offending.
"They were together, moving into a new place and he had obviously consumed too much alcohol during that process and it's got him into trouble," Leith said.
"Alcohol is the underlying issue. He knows that and he is addressing that. He has engaged with community mental health and drug addiction services."
Smyth had earlier been removed from a domestic violence programme due to his constant consumption of alcohol.
He pleaded guilty to contravening a protection order when he appeared in court on Tuesday.
Judge Matheson cancelled Smyth's sentence of intensive supervision due to expire in August and sentenced him to a further 12 months' intensive supervision.
The judge also sentenced Smyth to 80 hours' community work and said he would be judicially monitored for up to three months.
"Mr Smyth this has got to stop. Clearly, you've got a problem with alcohol and as a result of that, those within your family put up with nonsense," Judge Matheson said.
"I acknowledge you here today in a collar and tie and being contrite, but the reality is, once you drink alcohol, you become a different beast."
Judge Matheson gave Smyth a final warning.
"You are warned. I can tell you, I will be supervising judge and will monitor this," he said.
"If you are not doing the domestic violence programme, I will resentence you and you will be going down those stairs and out to Kaitoke."
