Police are investigating a home invasion where a man was repeatedly bashed on the head by an intruder at his Christchurch property last night.

The man went to the backdoor of his Bamford St, Woolston, home after hearing a noise, to find a masked person wearing dark clothes about 7pm on Sunday.

Detective Sergeant Brad Grainger, who is investigating the assault, said the intruder grabbed the 70-year-old man and struck him multiple times on the head with a sharp object before fleeing the scene.

The victim was treated at Christchurch hospital, but has been discharged.
