Neither Luxon's National Party nor the centre-left Labour won enough seats in parliament to form a government without minor parties in an election that put the two main parties neck and neck at 29% – just a few thousand votes separating them.

Preliminary results had National winning the most seats, which would give them a very slim majority if combined with their coalition partners – the populist NZ First and the libertarian ACT.
