Americans in Wellington will be the first in the world to vote in what is likely to be the turning point in the US primary elections -- Super Tuesday.
Democrats Abroad New Zealand will be the first group to vote at midnight tonight for their preferred Democratic candidate for the general election later this year.
New Zealand will be the first of 41 countries, and Wellington the first of 111 cities which will take part in the Global Presidential Primary.
The Republican Party doesn't hold a primary vote outside of the US.
The group says the midnight voting in New Zealand will give an indication of each candidate's "global presence" as well as their profile among the Democrats abroad.
Chair Kat Allikian says the group is proud to lead the Global Primary.
"We may not have thousands of Democrats living here, but what we lack in numbers we make up for with our passion for getting out the vote and helping ensure that the next President of the United States is a Democrat who represents our voice in the United States," she says.
Super Tuesday is the biggest day on the road to the White House, with 12 states having their say on who their respective Republican and Democratic nominees are for the general election later this year.
It has been a critical moment for a number of past presidential campaigns.
In-person voting in other participating countries will take place between March 1 and 8, with the final votes expected around March 20.
However, which way Wellington's Democrats will vote will be known just before 12:30am with local results from the Global Primary throughout the week.
The voting will take place at Wellington's Public Bar and Eatery on Courtenay Pl at midnight, though those wanting to vote should be at the venue by 11pm.
