Assuming both parties fail to reach 50% next year, I would like them both to decline NZF Its not worth it. If NZF wants to not play the game, that will end them. Fair play they got some stuff for becoming a coalition partner, but they have squeezed out far more than their seat share warranted.
Assuming NZF gets over the 5%, not a certainty and gets say one electorate seat they would still hold a balance of power or responsibility as Winston would have it. Now if Winston steps down in 2020 I feel that NZ will not get an electorate seat and will fail to get over 5% in which case problem solved.
