It could be argued, quite convincingly, that New Zealand's most enduringly popular minor political party is the Greens.
Since entering Parliament in 1999, they have never dropped below the 5 percent threshold. Today they have 15 MPs, their largest caucus ever, and consistently poll around 10 percent.
But while they are certainly popular, have they achieved more than other minor parties - ACT and New Zealand First?
