The mother of a dead toddler has told a jury in the Auckland High Court that her former partner would get angry and frustrated when her daughter cried.
The Crown has argued that Michael Martin was unhappy with his current relationship with Amy Lorigan when his frustration boiled over in June 2012.
Mr Martin is accused of assaulting Ms Lorigan's two-year-old daughter Leilani Lotonu'u from a previous relationship with so much force that he ruptured an organ in her stomach.
He has denied charges of ill-treating and murdering the child. His lawyers said the toddler was in the care of her mother.
Amy Lorigan told the court on Wednesday that, on one occasion while pregnant, Mr Martin put all of her and the child's belongings outside.
He later apologised and blamed his behaviour on drink.
However, Ms Lorigan said the accused was jealous and had said Leilani reminded him of Ms Lorigan's former partner, and he wanted to split up.
