SkyCity's big boss has been up the Sky Tower dozens of times, but has never tried the stairs - until now.
Chief executive Nigel Morrison is getting ready to take on the tower's 51 flights of stairs in this year's Firefighter Sky Tower Stair Challenge.
Celebrating its 11th birthday next week, the event will see 750 firefighters from around the country run up 1103 steps to raise money for Leukaemia & Blood Cancer NZ.
Mr Morrison has signed up to join the crowds alongside personal fitness trainer Lee-Anne Wann, who has been helping him change to a healthier lifestyle since late last year.
"It's a good cause and an important cause. Thanks to Lee-Anne, I'm in better shape than I've been in the last eight years. So if I'm gonna do it, it has to be now."
