He returned with a group of friends about 5 am the next day and about 6am woke her up, demanding she give him a love bite on the neck.
Ms Rangihuna-Atkins said she refused and he began choking her as the baby slept on a pillow beside her.
The baby started to cry and Kohinga pulled the infant by her legs to the bottom of the bed where he started choking her and yelled at her to be quiet, Ms Rangihuna-Atkins told the court.
Kohinga then threatened to kill the child and told the mother to leave the room. She refused.
"He said he didn't want her to be born and to die," Ms Rangihuna-Atkins said.
"I wasn't going to watch her die."
Kohinga's cousin then came in to the room and intervened.
Crown prosecutor Sarah-Louise Tapsell told the jury Kohinga had referred to the baby as "that ugly thing" and punched the woman repeatedly during the ordeal.
