WELLINGTON • New Zealand has followed Australia in banning China’s Huawei Technologies Co Ltd from supplying 5G wireless equipment to the nation’s telecommunications operators, citing national security concerns.

News of the ban came via Spark New Zealand, which said yesterday its intention to use Huawei 5G equipment had been blocked by the Government Communications Security Bureau (GCSB). The GCSB told Spark that, if implemented, its plan would “raise significant national security risks”, the company said in a statement to the stock exchange. The GCSB confirmed the ban in a separate statement.

New Zealand’s move comes after Australia in August blocked Huawei as well as ZTE Corp from supplying 5G equipment to its telecommunications operators. The Chinese companies have come under increased scrutiny in the US over fears their equipment could be used for spying.

Huawei said it’s looking into the situation and that the company has signed more than 20 commercial 5G contracts around the world.

“We will actively address any concerns and work together to find a way forward,” the Shenzhen-based company said in a statement yesterday.

“We remain committed to developing trusted and secure solutions for our customers.”

Huawei and ZTE have previously disputed they represent any such risks, as has the Chinese government, which described the Australian ban as “politically motivated”.
