Five pregnant women are among Mt Eden prison staff who have been sent home after an inmate was found to have contracted measles.
Various actions have been carried out at the Mt Eden Corrections Facility since the prisoner was identified with symptoms last Friday.
It became a confirmed case of measles the next day.
From Monday, vaccinations against the highly contagious disease will be made available to all staff at the Mt Eden facility, based on advice from the Auckland Regional Public Health Service.
Deputy national commissioner of the Department of Corrections, Andy Milne, told the Herald 41 of its staff had been identified as having had potential direct contact with the prisoner involved while he was said to be infectious.
