Columba College pupils were practising netball in the school's sports centre when a fire broke out in the ceiling this afternoon.
Fire and Emergency New Zealand spokesman Brent Dunn said a crew from Roslyn had arrived at Columba College shortly after 4pm after a report of a light fitting was on fire in the second storey of the Marsh Sports Centre.
Five crews were in attendance fighting what had been described as a "small fire".
The fire was quickly extinguished by 4.30pm.
Columba College principal Pauline Duthie said an electrical fire started in the ceiling while girls from the school, who were now standing outside in the rain, were practising netball.
No-one was injured and she praised the quick actions of staff and pupils.
A reporter at the scene said firefighters, some wearing breathing apparatus, were inside the sports centre.
