Firefighters have finished battling a large structure fire that kept them busy for nearly 10 hours overnight.
However, the cause of the blaze remains under investigation.
Fire and Emergency NZ was called to the Crockers Property Management head office, a commercial building on Manukau Rd in Epsom, at 8.20 last night.
They finally left the scene around 6 this morning.
"By 6am, we'd done everything we could," Northern Fire and Emergency shift manager Mark Richards said today.
