A 30-year-old man charged over a number of alleged rapes in Coolaroo and Roxburgh Park, in Melbourne's north, has been remanded in custody.

Davut Bulduk, who faces a total of nine charges, including seven counts of rape and two of aggravated burglary, has appeared in Melbourne Magistrates Court.

Police alleged he broke into a Coolaroo home on New Year's Eve and raped a 38-year-old woman.

They said he also allegedly raped a 16-year-old girl in late February after entering a house in Roxburgh Park.

During the filing hearing, the magistrate was told police would scrutinise CCTV footage as part of their case.

Bulduk did not seek bail and will return to court in mid-June.
