March 2013 - Mr Key admits the new head of GCSB Ian Fletcher (appointed February 2012) is old family friend, who he shoulder-tapped for the role. State Services Commissioner Iain Rennie maintains the appointment process was rigourous.
April 2013 - Kitteridge report leaked ahead of planned release, saying the GCSB may have illegally spied on 88 people in New Zealand. (Legality of 56 operations involving 88 individuals since 2003).

June 2013 - After Edward Snowden blows whistle on the National Security Agency in the United States, Prime Minister John Key tells Parliament he has sought an assurance from the GCSB that it is acting in accordance with New Zealand law and that it does not ask agencies in other countries to circumvent that law.
