The British government has decided to allow the Chinese telecoms company Huawei to have a limited role in the development of its 5G mobile network.
However it will be excluded from sensitive sites in Britain, including military bases and critical infrastructure.
The United States is suspicious of Huawei and has called on governments to lock the firm out of 5G networks.
The GCSB in New Zealand last year blocked Spark's application to use Huawei tech in its 5G rollout.
