Britons living in New Zealand have only a couple of days left to enrol to have a say on whether the United Kingdom quits the European Union.
A referendum on the issue will be held on June 23 and those wanting to vote must register by Monday.
Dubbed the "Brexit", the issue is dividing voters and has pitted factions in the ruling Conservative Party against one another.
Holding the vote was an election promise Prime Minister David Cameron made in 2015, but if the voters decide on an exit, his political future will be shaky.
Former London mayor Boris Johnson is pushing for the UK to leave the EU and is using his populist message in a bid for the country's top job.
