The turnout in the 2017 general election is up on the previous two elections.
The Electoral Commission says on Sunday 78.8 per cent of people voted, who were enrolled to vote as at 6pm Friday 22 September.
This compares with a final 77.9% turnout of enrolled voters in 2014 and 74.21% of enrolled voters in 2011.
The 2011 election was the lowest recorded voter turn out at a New Zealand parliamentary election since the adoption of universal suffrage in 1893.
The preliminary results on Saturday - National winning a total of 58 seats, to Labour's 45 - is based on 2,179,668 votes counted on election night, which includes 9866 informal votes, where a voter's intention was not clear.
Special votes still to be counted are estimated to be just over 384,000, or 15 per cent of the total votes.
This includes 61,375 votes cast from overseas.
The official election result is expected to be declared on October 7.
