"Piha is a tight-knit community and we understand this has been a stressful time for residents," Webb said. "We have received an overwhelming response from local residents and the wider public who have come forward with information.
"Further investigations are continuing in relation to multiple other fires in the area. At this stage police are not looking for anyone else and we cannot rule out the possibility of other charges being laid," he said.
The man will appear in the Tauranga District Court today.
Peter Chapman, who owns the Piha general store, said it was a relief to know the police had made an arrest in the case, which had brought the community closer together.
"The general feeling is the police have done a wonderful job along with fire investigators and we are also grateful for the fire volunteers in our community that the fires weren't worse," Chapman said.
Police say there have been at least 15 suspicious fires around Piha in the past fortnight.
