Cameron Smith and Monique Nees have cycled through 33 countries in just over a year.
The couple are now riding from Cape Reinga to Bluff, to raise money for suicide prevention.
"It has affected our community greatly," said Cameron. "Monique has lost cousins, family members, we've lost a lot of friends, our school has been affected. It was an obvious choice really, to build awareness around the subject. When we were growing up, it wasn't really a subject you."
The couple met at high school in Otago and have been together for over a decade.
"I'm 26 and Cameron is 28, so we've been together for a wee while - longer than a death sentence I think..." teased Monique. "We actually hadn't lived together until we moved to London. And since then, we've spent the last 15 months together, in a tent, so that's been fun."
