Citizen Initiatives since 1993
"A total of 33 petitions have been launched since 1993 on a wide range of topics. Only three have come to a vote, because all the other proposals failed to gain enough signatures to force a referendum. The target number for signatures is the key to looking at the initiative proposed by citizens.
The first citizens initiated referendum was held on 2 December 1995.
The question "Should the number of professional fire-fighters employed full-time in the New Zealand Fire Service be reduced below the number employed in 1 January 1995?" was unusual in that it aimed to elicit a "no" response. Turnout was low as the referendum was not held in conjunction with a general election, and the measure was voted down easily, with just over 12% voting "Yes" and almost 88% voting "No"."
