Prisoners and staff had to be evacuated from Mt Eden Corrections Facility last night after an inmate sparked a fire in their cell by tampering with an electrical socket.
"Staff responded immediately to remove the prisoner from the cell, and Fire and Emergency NZ were called," a Corrections spokesman.
The fire started at 10.27pm, the spokesman said.
Fire teams were able to contain and extinguish the fire.
No staff or prisoners were injured.
