This Saturday members of OceanaGold's Mines Rescue Team will be donning full rescue outfits and a 14 kilogramme BG4 closed circuit breathing sets before climbing 1103 steps over 51 flights of stairs.
There's no emergency. They are doing it to raise money for the Firefighter Sky Tower Stair Challenge.
Currently the Waihi team is in third place across the country for funds raised, and
team member Shay Perkinson is fifth overall on the individual leader board.
The Firefighter Sky Tower Stair Challenge is one of Leukaemia & Blood Cancer New Zealand's largest fundraising events and has completed its 15th year.
Each year firefighters from around New Zealand, Australia and the USA gain sponsorship and compete in this event at Auckland's Sky Tower, reaching a vertical height of 328 metres.
