Police are convinced the two men who carried out a "serious and abhorrent" attack an 84-year-old man in his home live close to their victim just north of Te Kao.
The attack occurred on Thursday night sometime between 1am and 5am, but most likely about 3.30am, at an isolated house 65km north of Kaitaia. The man needed hospital treatment for his injuries.
Senior Constable Tracee Knowler said a struggle ensued after two intruders pushed the man up against a wall, possibly dislocating his shoulder. They demanded alcohol, but left empty handed when they found he had none.
The man managed to raise the alarm by knocking on a neighbour's door about 5am. He was taken to Kaitaia Hospital for treatment.
Ms Knowler said she was confident the man's attackers lived in the area and urged anyone with information, even if it was at this stage just a rumour, to call her at the Houhora station on (09) 409 8822. The attack on an elderly man was "serious and abhorrent".
