Page "Referendum" Paragraph 76

Since 1993, New Zealand also has provision for non-binding citizens-initiated referendums.

To initiate a citizens-initiated referendum on a particular issue, proponents of the referendum apply to the Clerk of the House of Representatives, and once the question wording is determined, proponets have twelve months to compile a petition containing signatures from at least ten percent of all registered voters.

Only four citizens-initated referedums have gone to a vote: one in 1995, two in 1999, and one in 2009.
