Police have commenced an operation on the Hibiscus Coast into a fire deliberately lit at a cafe over the weekend.
It comes as Waitematā North CIB continues to investigate another attempted arson and damage at nearby Ōrewa businesses in recent months.
Waitematā North Area Commander Inspector John Thornley says the most recent fire occurred late on Saturday 1 November.
"Operation Governor has been set up to investigate the most recent fire on the main strip in Ōrewa," he says.
"It's fortunate that no one has been harmed as a result of this fire, which is considered to be deliberately lit."
Residents can expect to see a larger Police presence around Ōrewa over the coming days.
"I want the community to know that these attacks on local businesses won't be tolerated and we are working hard to hold those responsible to account," Inspector Thornley says.
"These arsons are not only damaging property, but it's affecting peoples' livelihoods, and Police is open-minded about whether any of these incidents are linked."
It's highly likely the community's information may prove pivotal in this investigation.
Inspector Thornley says the investigation team will be engaging with the public over the coming days.
"We want to hear about any suspicious activity that people might have seen on Saturday night," he says.
"I'm asking anyone with dashcam footage around the Ōrewa township, between 10pm and midnight, on Saturday 1 November to make themselves known to the investigation team.
"No piece of information is too small, so please come forward as soon as possible."
Anyone with information can update Police online now or call 105 using the reference number 251102/4265.
