A student has pleaded guilty in North Shore District Court to forging scores of drivers' licences.

Marcus Lim, 17, admitted one charge of forging a drivers' licence, and a new charge of forging 150 drivers' licences.

The Auckland Grammar School boy was remanded on bail to reappear in court for sentencing on April 20.

His lawyer William Spring told the court police were not seeking a term of imprisonment.

A computer seized by police earlier this month contained a database of 250 names of people understood to have received a forged licence.

Almost all were 16 and 17-year-olds from 15 Auckland schools.

More than 60 students have returned their fake licences into police stations, although police believe that many will never be found.
