6 September 2008 marks 60 years of New Zealand citizenship. Over half a century ago New Zealand's Parliament passed the British Nationality and New Zealand Citizenship Act 1948, which made New Zealanders "British subjects and New Zealand citizens" from 1 January 1949, rather than solely British subjects.

2007 marked one hundred years since New Zealand took the first step towards becoming a republic, by declaring itself a dominion within the British Empire.

The Head of State Referenda Bill is a members' Bill drawn from the Parliamentary ballot of members Bills on 14 October 2009. If passed would enable two referendums on the republic issue.

Commonwealth Common Cause is an alliance of Commonwealth republican groups, of which the New Zealand Republican Movement is a member. Sharing a Commonwealth heritage, four republican organisations in Australia, Britain, Canada and New Zealand joined forces in April 2005 to pursue their common cause, to bring about four new Commonwealth republics across the globe.
