The government is investigating reports North Korea is launching cyber attacks through New Zealand's networks.
A report from threat intelligence company Recorded Future says New Zealand is one of eight countries where North Korea has a "large and active presence".
Foreign Minister Gerry Brownlee said he was not sure how accurate the report was.
"What it appears to indicate is that those who are more elite in North Korea and perhaps other who have access to devices are using tunneling apps to be able to access the internet from within North Korea.
Mr Brownlee said the government's spy agency was leading the investigation.
