World Famous Ancient Kauri Log Staircase - enjoyed by 100,000 visitors yearly
Giant Kauri Staircase
Radiocarbon dating confirmed that this tree had been perfectly preserved in the swamp for 45,000 - 50,000 years. Growth rings tell us it had lived 1087 years before it fell more than 45,000 years ago.
It is thought to be the only internal log staircase in the world! â€“ if not, definitely the oldest.
Extracting the log was an engineering feat
Exctracting the giant log was an engineering feat...
The crew firstly tried extracting the tree in one piece, but after snapping 2 winch ropes with a breaking strain of 90 tonnes each, and pulling apart 2 x 2.5 inch shackles, cut a 110 tonne section off, pulling that out first, and the remaining 30 tonne piece afterwards.
Carving the staircase took time and kiwi ingenuity
It took over 500 hours to chainsaw out the staircase...
A half metre thick reinforced concrete pad was poured, the log stood upright and construction of the new shop commenced over and around it.
The staircase itself took Dave 300 hours to chainsaw out and two other men another 200 hours to finish it.
