Emergency services have rushed to a fire at a Penrose panel and paint shop.
A Fire and Emergency New Zealand (FENZ) spokesman said they received multiple calls about 10.33am alerting them to a fire on Church St.
The building was well ablaze on arrival and the response effort was elevated to a second alarm, the FENZ spokesman said.
Initially, the response effort was focused on protecting surrounding buildings, he said.
"Once they got it under control a bit, they went into an internal offensive mode."
