Prime Minister John Key has given an assurance that the US National Security Agency has not been involved in spying on New Zealanders.
There were revelations last week from a former NSA contractor, Edward Snowden, that the United States and Britain have a deal allowing the agency to analyse and store the personal information of British citizens.
With New Zealand belonging to the Five Eyes intelligence sharing agreement, along with Britain and America, there have been questions about whether a similar arrangement exists here.
But Mr Key on Thursday dismissed the idea that the Government Communications Security Bureau is getting around the rules about spying on New Zealanders by using NSA data.
Mr Key said the Government ensures that its agencies do not circumvent the domestic law by using an offshore agency.
