William Barnes, the winner of Mastermind New Zealand, has listed the famous chair on Trade Me in support of the Samuel Gibson Memorial Trust.
Mr Gibson, who suffered from brittle bone disease, died this year after falling out of his chair at the Air New Zealand Hawke's Bay Marathon while he was raising money for a boy with a similar condition.
Mr Barnes said he was a huge admirer of Mr Gibson and wanted to keep the Bay adventurer's legacy going.
"He was such an excellent person and I was influenced by his positive attitude and gratitude towards his upbringing and life."
The starting bid for the chair was $6000 and Mr Barnes said he has already had a lot of interest and one keen potential bidder.
