Elections are held on Republic Day, every second January.
"We celebrate by closing off the main road here with borders," Kennedy said. "You have to buy a passport to get in. It's a good money-spinner for us.
"The money goes to the republic and we spread it out to the schools and the halls and other things that need money."
Recently, a portion of the republic's funds bought a public artwork by Whanganui artist, Jack Marsden-Mayer, who himself has been a tourist in the small town.
"I was travelling around New Zealand," said Marsden-Mayer. "Went down the Forgotten World Highway and found that little place, stayed at the campsite, had a few beers in the pub."
The driftwood sculpture of a large bullock will be officially unveiled next month.
"The bullock was a big part of breaking this country in, bullock teams pulling the logs out back in the day," said Kennedy. "So I thought it would be fitting for our area, a bullock pulling a log."

The Whangamomona Hotel is the heart of the town and the "seat of government", issuing passports and providing an old-school kiwi experience.
