"Cancer doesn't sleep, and that's what we have to remember," she said.
The team camped nearby and took naps in between walking.
Cleland said the Levin group was proud to have completed a range of successful fundraising ventures over the past year, helping to fund cancer support and research in Horowhenua.
They raised a total of $7000 by holding a fashion parade, quiz night and large raffle, as well as some sponsorship for the relay.
"For a small town like Levin, that's huge," she said.
"[Relay For Life] was a celebration of a lot of hard work, it was a big, fun atmosphere."
Cleland said it was also important to celebrate cancer survivors as well as those who had passed away, as it showed the sense of hope the group focused on in their work.
Relay For Life is largely organised by volunteer committees supported by the Cancer Society, the organisation said.
"[It] brings teams of friends, work colleagues and families together in a fun, carnival like atmosphere to fundraise for the Cancer Society. It is a time to celebrate and remember loved ones affected by cancer - and to fight back by raising awareness and funds."
