New Zealand's move follows a similar decision in Australia.
New Zealand has become another country that has blocked the use of China's Huawei telecommunications equipment to build a new generation 5G cellular network for national security issues.
Spark, New Zealand's largest telecommunications operator, announced on Wednesday that the news agency had blocked the use of Huawei's 5G network equipment because it posed a "significant risk to national security." Spark is needed to inform GCSB about the 5G Plan.
New Zealand's GCSB director, Andrew Hampton, said that if Spark had used the Huawei 5G network, it would significantly increase national security risk. Spark still wants to complete the new 5G network in July 2020.
World pressure is increasing for the involvement of Chinese technology companies for security reasons. In particular, the United States urged its allies to exclude Chinese suppliers from building a 5G network for fear of cyber security. The new 5G network will be a significant wave of mobile infrastructure.
Huawei, the world's largest telecommunications maker, faces rejection from foreign governments who fear their technology can be used for espionage.
New Zealand's move follows a similar decision in Australia, which also blocks the use of Huawei and ZTE China's technology to build 5G networks for security reasons. The United States and Britain have also voiced concerns about Huawei and the company being questioned in Germany, Japan and South Korea.
The Wall Street Journal, the US daily, said last week that the government in the US was trying to convince wireless service providers to avoid using Huawei equipment.
In the UK, in July, the Security Council warned in its report that there was only "very limited certainty" that Huawei's telecommunications facilities did not pose a threat to national security.
New Zealand is a member of the Five Eyes intelligence alliance, which includes the United States, United Kingdom, Canada and Australia. Only one country does not prevent Huawei. Papua New Guinea said this week that it would continue the agreement with Huawei to build its Internet infrastructure.
