The use of mixed-member proportional representation allows ready conversion of a party's support into a party vote percentage and therefore a number of seats in Parliament. Projections assume the new electorate of Takanini will be won by either Labour or National[1] and that Botany will be returned to National,[2][3] but otherwise assume no material change to the electorate seats held by each party. Parties that do not hold an electorate seat and poll below 5% are assumed to win zero seats.
When determining the scenarios for the overall result, the minimum parties necessary to form majority governments are listed (provided parties have indicated openness to working together). Actual governments formed may include other parties beyond the minimum required for a majority; this happened after the 2014 election, when National only needed one seat from another party to reach a 61-seat majority, but instead chose to form a 64-seat government with Māori, ACT and United Future.[4]
