"All too often we see defenceless animals being harmed for no reason and this is a case where there should be a strong message from the courts that this behaviour will not be tolerated."
Senior Sergeant Brian Swann, of Mid North police, described the attack as "horrendous".
The man's teenage son called police, as did several other people in the neighbourhood who heard the puppy's howls of distress.
It could even be heard at the police station about two blocks away.
Officers took the puppy, named Valley, to Bay of Islands vets but its injuries were so severe it had to be put down. Injuries included multiple skull fractures, broken teeth, bruising to the eyes, brain swelling and bleeding from the nose and mouth.
