Emergency services were kept busy attending a number of callouts on Saturday.
Several fire crews are dealing with blazes at three shops in the Southgate Retail Centre.
A pile of rubbish set alight in New Lynn saw the fire spread to a nearby building and some tyres.
The blaze is now under control, but police believe the fire may be suspicious.
Meanwhile, hazardous material crews are investigating a potential oil spill under the Harbour Bridge, where oil is reported to be leaking from boat.
