Three Maori roll seats could affect the outcome of Saturday's election, while others on the general roll might change hands without making a difference to the overall outcome.
Here are the key seats to watch:
Maori Party co-leader Te Ururoa Flavell must retain the seat to ensure his party continues to have a presence in parliament. This time, Waiariki is a straight fight between Flavell and Labour's Tamati Coffey. The party has partnered National for nine years but could go either way. Flavell's 2014 majority: 3889.
TE TAI HAUAURU
There's a good chance the Maori Party could grab this one from Labour. Former rugby league international and Kiwis captain Howie Tamati is their candidate, up against Labour's sitting MP Adrian Rurawhe. Apart from his league mana, Tamati has served 15 years as a New Plymouth district councillor. Rurawhe's 2014 majority: 1554.
TE TAI TOKERAU
Can Hone Harawira get back into parliament? The Mana Party leader lost the seat to Labour's Kelvin Davis in 2014, but this time the Maori Party is standing aside to give him a better shot at it. In return, the Mana Party isn't contesting any of the other Maori roll seats. As a partner to a main party, he would likely favour Labour. Davis' 2014 majority: 743.
National's Chris Bishop has high hopes of taking Hutt South from Labour now veteran Trevor Mallard has moved onto the list. Newbie Ginny Andersen carries Labour's torch against Bishop, a list MP who has been working hard in the electorate and gave Mallard a close run last election. Mallard's 2014 majority: 709.
Peter Dunne's decision to quit has thrown the seat open, and it's an odd one. National won the party vote by a big margin in 2014 but didn't campaign for the electorate vote so Dunne would have a better chance. He nearly blew it with Labour running a strong second. National's Brett Hudson is standing again while Labour has high-profile Greg O'Connor. Dunne's 2014 majority: 710.
Winston Peters won it in a 2015 by-election, rubbing National's nose in the dirt. Can he sustain that in a general election? The NZ First leader sets huge store by being an electorate MP and he's made a raft of promises to Northland voters. National's Matt King is going to try to take him out. Peters' by-election majority: 4441.
ACT holds the seat courtesy of the National Party which has again asked its supporters to vote for David Seymour. He'll win it again but ACT desperately needs more than one MP in parliament. For that it must lift its share of the party vote above it's abysmal 0.69 per cent in 2014. Seymour's 2014 majority: 4250.
Always an interesting seat. Labour held it for decades until Nikki Kaye snatched it in 2008. She's managed to hold onto it since then, but not by much. In 2014 she was given a close run by an up-and-coming Labour MP - Jacinda Ardern. Kaye's 2014 majority: 600.
