The cause of a spectacular fire at the Port of Tauranga on Friday has been identified.
Bay of Plenty specialist fire investigator Luke Burgess told the Bay of Plenty Times: "At this point, it appears that the fire started from charging batteries for power tools."
The batteries were believed to have been on a shelf when the fire started, spreading through the workshop.
"I'm still doing a bit of research but it certainly appears to be around that."
