A UK High Commission spokesman told the Herald that although they can't enable Brits to cast votes, they recently undertook a push to help expats register to vote.
The High Commission will use a big red bus to offer support and services to fans at every stop during the British and Irish Lions tour.
Onboard the bus parked up at Whangarei's Town Basin, British High Commission spokesman Callum Valentine said it will make rugby tourists feel at home despite being halfway across the world.
"It's a mobile version of the British High Commission. We're taking the office on the road to reach the British nationals who are coming here."
Valentine said there are an expected 30,000 Brits arriving on our shores during the tour, and should anything go awry for them the bus will be there to help.
"We'll be able to facilitate emergency travel documents, things like that, if people happen to lose their passport we will be able to help them out. We'll also be doing some preventative messaging to try and avoid that sort of thing. It's about helping British nationals and providing support for them."
