The following is a detailed results break down of the 2017 New Zealand general election, which was held on 23 September 2017.
Preliminary results were gradually released after polling booths closed at 19:00 (NZST) on 23 September. The preliminary count only includes advance ordinary and election-day ordinary votes; it does not include any special votes. Special votes include votes from those who enrolled after the deadline of 23 August, those who voted outside their electorate (this includes all overseas votes), hospital votes, and those voters enrolled on the unpublished roll.
All voting papers, counterfoils and electoral rolls are returned to the electorate's returning officer for a mandatory recount; this also includes approving and counting any special votes, and compiling a master roll to ensure no voter has voted more than once. Official results, including all recounted ordinary votes and special votes, are due to be released by 14:00 on Saturday 7 October 2017.
Parties and candidates have three working days after the release of the official results to apply for a judicial recount. These recounts take place under the auspices of a District Court judge (the Chief District Court Judge in case of a nationwide recount),Sections 190 and 191, Electoral Act 1993 and may delay the return of the election writ by a few days.

Electorate results
At the 2014 general elections, four electorates were won by candidates with a margin of fewer than 1,000 votes: Auckland Central, Hutt South, Ōhāriu and Te Tai Tokerau.
Hamilton West is considered to be New Zealand's bellwether seat. Since the formation of the electorate in 1969, the winning candidate has been from the party that has gone on to form the government, with the exception of 1993 when it elected a Labour MP while the National went on to form the government (albeit with a one-seat majority). Along with Hamilton West, Maungakiekie and Rotorua have been bellwethers in the MMP era, swinging with the government at every election since 1996.
