One New Zealand condemned a second suspected arson attack on a mobile site in just two weeks, calling for the community to report any suspicious behaviour around its infrastructure and assuring customers they can make emergency calls in the impacted area.

The site in Wanaka, a town in the South island, was completely destroyed and will take at least four weeks to rebuild, the operator explained in a statement.

While traffic is being shifted to other mobile sites in the area, One NZ cautioned coverage has been degraded, which will cause congestion at peak times. The company, however, stated customers will be able to make emergency calls thanks to industry-wide emergency protocols.

The latest attacks follow four similar ones in the region in recent months.

One NZ is the second-largest mobile player in New Zealand, with 2.3 million connections, behind market leader Spark with 2.6 million, data from GSMA Intelligence showed.
