"In France, the government is 57 per cent of the economy (and) their top tax rate is 55 per cent," he tells a crowd of both party faithful and the curious in Hamilton.
"(The NZ left wing's) policies are already in place.
"So there's a country they could all go to and leave us alone and save themselves the time of ruining New Zealand in the process.
"I've suggested it to them but they don't seem so keen. I can't think why. Maybe they don't have a fire extinguisher."
As campaign rev-ups go, it does the job, drawing chuckles from the crowd and making a point, especially given France's recent protest troubles.
Mr Seymour, one of parliament's best performers, is in his element at this town hall meeting, delivering an unscripted half-hour speech on topics across the political and policy spectrum.
He talks tax, small government, easier health access, debt, superannuation, family violence and more, finishing on the need to diminish the role the Treaty of Waitangi plays.
This is classic fare for the libertarian free-market ACT party, which Mr Seymour inherited as a partyroom of one and built back into a force of Kiwi politics.
This term, ACT contributed ministers around the cabinet table for the first time, with Mr Seymour serving as deputy prime minister.
In 2026, ACT is eyeing its best ever party result, with polling around 10 per cent and with higher aspirations, well above its 8.6 per cent in 2023.
The November 7 election is existential for Mr Seymour, who has been in parliament 12 years with ambitions for shrinking government.
While landing regulatory reforms alongside some public service "right-sizing", ACT has been frustrated with the speed of pace in the coalition government, but pleased with pledges to cut thousands in a second term.
"Here we are in New Zealand with 28 ministers ... and 39 departments and we wonder why nothing gets done," he said.
"Our government is too big and too complicated. Our economy is too small and has been strangled by our government."
This time around, ACT has been bolstered by high-profile recruit Paul Henry, a long-time broadcaster.
Mr Henry is best known to Australians for an ill-fated short stint on Channel 10's breakfast show, but to Kiwis he is known for reporting on, or hosting, just about every show under the sun in a four-decade career.
Mr Seymour has lauded Mr Henry's work speaking to 7000 people at 37 town hall-style meetings over recent months.
While their political fate is intertwined with the National and NZ First parties - with the right bloc in a tight race with the left - all is well and bright on the ACT campaign.
"Please get out and give your party vote to ACT to re-elect the coalition so we can go further and faster on the issues that you care about," he said.
