How seats are shared out
The Sainte-Laguë method, in four steps.
1Who qualifies
At least 5% of the party vote or one electorate. Seven parties qualify; Te Pāti Māori through its electorates.
2Divide by 1, 3, 5, 7…
Each party's votes are divided by 1, 3, 5, 7… to give its quotients. Example, 10 seats:
| Divide by | 1 | 3 | 5 | 7 | 9 | 11 |
|---|---|---|---|---|---|---|
| A · 50,000 | 50,000 | 16,667 | 10,000 | 7,143 | 5,556 | 4,545 |
| B · 30,000 | 30,000 | 10,000 | 6,000 | 4,286 | 3,333 | 2,727 |
| C · 20,000 | 20,000 | 6,667 | 4,000 | 2,857 | 2,222 | 1,818 |
The 10 biggest win: A 5, B 3, C 2.
3The top 120 win seats
All quotients are ranked together; the top 120 each win a seat. In 2026 the last seat in is Labour's 36th and first out is National's 36th, 51 behind.
4Overhang
A party that wins more electorates than its share keeps them, and Parliament grows. National has 42 electorates for a share of 35, Te Pāti Māori 5 for 1: 131 seats, majority 66. So National's quota can fall without it losing a seat.
