What is MMP?
MMP stands for Mixed Member Proportional representation, the electoral system used in New Zealand.
How MMP was adopted
A majority of new zealanders voted for it twice: first in a non-binding referendum in 1992 and again in a binding referendum at the election the following year.
Voting process
New zealanders have two votes: one for a local representative and one for a political party.
Seat allocation
There are 120 seats: 72 electorate seats won by candidates in specific areas and 48 list seats allocated based on party vote proportions.
Overhang rule
If a party wins more electorates than its share of party votes allows, extra seats can be added to parliament to ensure proportional representation.
Party vote thresholds
A party must win at least 5 percent of votes or an electorate seat to win a seat in parliament.
Government formation
The party with more than 50 percent of seats becomes government; otherwise, parties negotiate to form a coalition or confidence and supply agreement.
MMP referendum debate
National leader Christopher Luxon has proposed another referendum on MMP after the 7 november election to test public support for the system.
MMP history
Mmp was first adopted in 1996 after a 1992 non-binding referendum and a 1993 binding referendum confirmed public support for the change.
MMP changes
The national-led coalition rejected several proposed changes to mmp in 2024, including restrictions on early and same-day voter enrolment.
The essence
New Zealand uses MMP to elect 120 parliamentary seats with 72 electorate and 48 list seats, ensuring party vote proportions match seat distribution.
