Concerns have mounted globally about the potential for the Chinese government to access users' location and contact data through ByteDance, TikTok's Chinese parent company.

The depth of those concerns was underscored this week when the Biden administration demanded that TikTok's Chinese owners divest their stakes or the app could face a US ban.

In New Zealand, TikTok will be banned on all devices with access to parliament's network by the end of March.

Parliamentary Service Chief Executive Rafael Gonzalez-Montero said in an email to Reuters that the decision was taken after advice from cybersecurity experts and discussions within government and with other countries.
