A 31-year-old man was arrested and faces charges including aggravated burglary and assault following the incident, which occurred at an Opawa address about 3.30am on Sunday.

Returning home, the 18-year-old disturbed an intruder and was seriously assaulted.

A family member who came to help was also assaulted before the intruder fled. 

Police believe the family member's intervention stopped any further injuries to the 18-year-old. 

Both victims required hospital treatment.

The 31-year-old male is due to appear in the Christchurch District Court tomorrow.
