Some Wānaka residents are concerned a ‘fire bug’ is on the loose after another incident where a cell phone tower appears to have been set alight.

Police were notified of the incident on Stone Street at around 11.40pm on Tuesday (October 7).

A police spokesperson told the Wānaka App police are making enquiries to determine the circumstances of the incident.

“Members of the public may see an increased police presence in the area while enquiries are ongoing,” the spokesperson said.

One NZ head of sustainability & corporate affairs Nicky Preston said the incident was the result of "reckless behaviour" which "puts the safety of our communities at risk”.

“With reduced mobile coverage in parts of the area, residents and visitors will experience disruptions to service. However, One NZ customers will still be able to make 111 calls thanks to industry-wide emergency protocols," she said.

“We’re working urgently to restore full coverage as soon as possible, but with connectivity now being essential to live, work and play online, this will impact locals and visitors to Wānaka.”

A Fortysouth cell phone tower and two data boxes were damaged by fire in Albert Town late last month (September 20).

In July significant damage was done to a cell tower on Lindis Pass-Tarras Road (State Highway 8).

Queenstown Lakes District mayor Glyn Lewers put out a statement condemning “the recent arson attacks”.

“I am deeply concerned and disappointed by the recent acts of vandalism targeting mobile infrastructure in our community. The deliberate destruction of a One NZ cell site in downtown Wānaka — the second such attack in as many weeks — is not only reckless, but it puts the safety and wellbeing of our residents and visitors at risk,” he said.

He urged anyone with information to report it to police.
