Police and fire officers are investigating a possible connection between three fires they believe were started by arsonists early this morning.
At around 2am fire fighters were called to a fire in the basement car park of Shore City mall in Anzac St, Takapuna.
Fire risk management officer Melissa La Roche says a rubbish bin containing cardboard boxes was set alight.
Sprinklers directly above the bin doused the fire before it was contained by fire fighters shortly afterwards.
Just 15 minutes later fire fighters arrived at a power transformer on Pupuke Rd, Takapuna where a pile of rugs leaning against it and other inorganic waste nearby was alight.
Superficial damage to the transformer occurred, but the fire was soon extinguished.
Three hours later at around 5.15am a fire occurred at the wooden platform above the skate park at Marlborough Park in Glenfield.
The fire burnt through the timber and a large area surrounding the skate park has now been cordoned off as police and fire officers investigate.
Ms La Roche says the cause of all three fires has not yet been confirmed, but it is believed they may have been acts of arson.
Once the results of tests for hydrocarbons, or petrol, are available they will determine whether the fires are suspicious, she says.
North Shore CIB detective sergeant Greg Ander says the Marlborough Park area is a popular hang out for local youths.
He says it is important anyone with information, or that witnessed any suspicious activity, comes forward to assist police with the investigation.
Call North Shore Policing Centre on 477 5000 or Crime Stoppers anonymously on 0800 555 111.
