The Cabinet National Security Committee (NSC) is a cabinet-level committee of the New Zealand Department of the Prime Minister and Cabinet that was created in October 2014 by the Fifth National Government. This body is modelled after the British National Security Council and the Australian National Security Committee of Cabinet. The NSC is headed by the Minister of National Security and Intelligence. As of 2015, that position is currently held by Prime Minister John Key.
The NSC is given oversight over New Zealand's intelligence community and security services and tasked with considering policies and proposals relating to those departments. Another function of the Cabinet National Security Committee is to coordinate and direct national responses to major crises or national security problems. The members of the Committee are the Prime Minister and Ministers responsible for the civil defence, the defence, foreign affairs, Government Communications Security Bureau, New Zealand Security Intelligence Service, and police portfolios. As of November 2015, some known members include John Key, Gerry Brownlee, Steven Joyce, Amy Adams, Chris Finlayson, Murray McCully, and Michael Woodhouse.
