Hastings man Trent Owen Ngaruhe Hapuku has been sentenced to nine years in prison for killing his partner's five-month old son, who interrupted him while playing a video game.
Hapuku delivered the fatal blow to Mikara Reti while alone with the infant in his girlfriend's Flaxmere sleepout on January 11 last year.
The 23-year-old appeared for sentencing in the High Court at Napier this morning after being found guilty of manslaughter last month.
Justice Forrest Miller imposed no minimum term of imprisonment, but said there was an "available inference" Hapuku had lost his temper with the infant while he was concentrating on a PlayStation game.
Mikara's mother Jamie wept while reading a victim impact statement and described her son as "the best baby anyone could ask for".
