Brits living in New Zealand have only got a couple of days to enrol for their their say on the Brexit.
A referendum on whether Britain should stay in the European Union is being held on June 23 and those wanting to vote must register by Monday.
Dubbed the "Brexit", the issue is dividing voters and had pitted factions in the ruling Conservative Party against one another.
Held after an election promise by prime minister David Cameron in 2015, a vote favouring an exit could force his resignation.
Former London mayor Boris Johnson is pushing for a fissure and is using his populist message in a bid for the country's top job.
British citizens living abroad can apply to be an overseas voter in the referendum.
To do so, they must have been registered to vote there in the past 15 years and be eligible to vote in parliamentary general elections and European parliament elections.
Those too young to vote when they left Britain can do so if they were left no more than 15 years ago their parents or guardians were registered to vote.
