An Auckland woman has been arrested over the illegal alteration of drivers' licence details for high school students

Police believe she was doing it so the students could get into Auckland bars and clubs using fake IDs.

The 18 year old has been charged with a fraud related offence and will appear in court tomorrow.

Acting Senior Sergeant Lisa Woodward says, if proved, the woman's deliberate actions have put large numbers of young people - including 16 and 17 year olds - at potential risk of harm.

She says police investigating the case have identified a number of other people who will be spoken to.
