The website 'The Intercept' has published top-secret documents from whistleblower Edward Snowden that suggest America's National Security Agency and Britain's Government Communications Headquarters hacked Dutch SIM card manufacturer Gemalto to obtain the encryption keys of the cards.
This would have allowed them access to personal data and the ability to listen to conversations.
Spark has told Radio New Zealand that it did source from Gemalto though said it had no evidence to suggest the hack had affected customers.
Other telecommunication providers spoken to by Radio New Zealand said they did not use the manufacturer.
Gemalto is investigating but said that all early signs suggested SIMs were secure.
