Unlike the general election, a preliminary count for the euthanasia referendum was not conducted on election night (17 October 2020). Instead, the referendum votes were counted alongside the mandatory election recount. All voting papers, counterfoils and electoral rolls are returned to the electorate's returning officer for counting. During the count, the returning officer approves and counts any
special votes, and compiles a master electoral roll to ensure no-one has voted more than once. To simplify processing and counting, overseas votes are sent and counted at the Electoral Commission's central processing centre in
Wellington, rather than to electorate returning officers. Preliminary results for the referendums were released by the Electoral Commission on 30 October 2020. These results had 65.2% of people in support of the legislation. Following the counting of the 480,000 special votes, official results for the general election and referendums were released on 6 November. Based on the final results, 65.1% of people supported the legislation while 33.7% opposed it. Three
South Auckland electorates — , and — voted against the End of Life Choices Act, perhaps due to
conservative evangelical Pasifika Christianity's strength in those areas. By contrast, over three quarters of and voters supported introduction of the End of Life Choices Act in this referendum. Although these are metropolitan electorates, there were several other electorates that polled over seventy percent support for the proposed legislation that were not necessarily urban. The new legislation took effect on 7 November 2021.
By polling place location As each polling place had only one ballot box for ordinary referendum votes, ordinary votes were broken down by the general electorate where the polling place was located. Special votes were broken down by electorate. Both ordinary and special votes have been combined in the following table. == Notes ==
