Is MMP working or should it be changed?

NZ First Leader Winston Peters will soon become our acting Prime Minister, despite receiving less than 7 percent of the vote, prompting fresh calls to reassess our electoral system.

Anti-MMP campaigners have been pushing to get rid of the voting system since it was introduced in 1996.

Former Prime Minister John Key was among them, he held a referendum on the issue in 2011 but the majority of Kiwis opted not to change MMP.

However, even staunch supporters agree there are ways MMP can be improved, including lowering the 5 percent threshold and abolishing the "coat-tailing" rule.
