Taylor added the Newmarket fire in August was at public toilets in the train station, which caused significant alarm.
“As a result of our investigation, and with the assistance of a number of other workgroups within police, we located a person of interest.”
The 33-year-old man is due to appear in the Papakura District Court on charges of arson.
Taylor said if it weren’t for the quick response by members of the public and attendance by police and Fire and Emergency NZ, the fires could have been much more serious.
“Police would again like to thank those who provided information which assisted us in our investigation.
“We take all reports of crime seriously, especially those that have the potential to cause harm.”
He added it was a timely reminder for everyone to check they have working smoke alarms at their property.
