The fire was put out about 3.45pm, after a local resident heard an explosion just after 1pm at the Islington Substation on Roberts Rd.

"I heard three loud explosions and I just thought it was something falling of the back of a truck just driving past, had a look out the window and there were big balls of smoke and fire coming out of there so it was pretty exciting," Hornby resident Jenee Pullen, who was sitting in her lounge, said.

"Then I called 111 when I [saw] all the smoke and shut all my windows and doors just in case.

"When I was standing at the door I could feel the heat coming off the fire ... It was about five minutes before the fire engines and ambulance turned up."

The Fire Service said oil in one of the substations capacitors caught fire and was fully ablaze when fire crews arrived at the scene.

Transpower spokeswoman Rebecca Wilson Fire said it was too early to determine whether the blaze was related to yesterday’s earthquake or any subsequent aftershocks.
