Spark has still to decide whether it will submit a revised proposal to the GCSB on the involvement of Huawei in the development of our 5G network.
The initial plan was knocked back by the security bureau, although the Government hasn't yet decided whether to follow that recommendation.
In a twist, the UK Government is now giving Huawei the go-ahead for 5G networks there.
The Financial Times reports the British believe they can mitigate any risks arising from the use of Huawei equipment.
Spark says it's in discussions with GCSB officials.
Financial Times journalist Demetri Sevastopulo broke the news of Huawei's decision.
He said it's a moral defeat for America's efforts to stop Huawei's spread.
He told Kate Hawkesby New Zealand will be caught in the middle of a new dispute between the two allies.
"It outs America in a bind but I think we will probably see America put pressure on the British Government over the next few months specifically over this issue."
