Wellington police have released a sketch of man who broke into a woman's bedroom while she was sleeping early on Sunday morning.
The student woke to find the man in her Aro Valley flat, and the man fled on foot after a brief struggle.
He has been described as aged 25-35, of muscular build and about 1.8m tall.
Detective Jocelyn Bell said the woman was shaken by the ordeal.
Police were asking anyone who saw anything suspicious in the area, or who could identify the man, to contact them.
