Two Whanganui firefighters will have family members in mind as they haul themselves up the Sky Tower's 1103 steps in Auckland later this month.
The River City (Whanganui) Volunteer Operational Support Team will compete in the Sky Tower Stair Challenge on May 28.
The two-man team is made up of operational support firefighters Aaron Whitford and Thomas Signal.
The charity event raises money for Leukaemia and Blood Cancer New Zealand and is particularly relevant to Mr Signal, who has lost several people close to him to the cancer, including his father-in-law last year.
"Basically, I'm saying they're doing it with me," he said. "It's a self-challenge thing but mainly I'm doing it for the father-in-law."
