Judge Christopher Harding sentenced him to five months of imprisonment, to be served concurrently with his existing four-year sentence.
The court was told that Peratiaki had already made a donation of $1000 to the SPCA – in 10 instalments of $100.
A police summary of facts said that Peratiaki, 25, was eating an apple in a grassed area of Hawke’s Bay Regional Prison when he saw the duck.
He threw the apple at the duck, striking it in the body, then ran towards it and kicked it with force.
The duck tried to fly off but came down on the grass again.
Peratiaki followed it and stomped on its head, leaving it badly injured and immobile.
Another man nearby came over and put the duck “out of its misery”. The summary did not make clear if the other man was an inmate or a member of the prison staff.
The summary of facts included no explanation for the attack.
Peratiaki was sentenced to four years in prison last year for repeatedly assaulting, injuring and causing grievous bodily harm to his partner, including while they were trapped in shearers’ quarters together during the Covid-19 lockdown in 2020.
The violence began when they were living in Hawke’s Bay and continued after they moved to Auckland and later to Nelson.
It happened frequently, mostly when Peratiaki was drunk.
The Nelson District Court was told in April last year the victim often had a black eye and was strangled by Peratiaki about 20 times during their relationship, each time to the point where she was unable to breathe.
At other times, he rendered her unconscious by stomping on her head or throwing her head-first into concrete.
