At the wool weigh before the judges on Sunday, 20 sample sheep from the flock were shorn at an average of 1.062kg of wool per lamb, just edging over the minimum required for the record attempt to go ahead.
Thus, more than 660kg of fine wool was shorn during the day.
Harder is no stranger to world records, having missed a ewe shearing record bid at the age of 20 in February 2020.
Observer and shearer Rocky Wegner, who spoke with Harder afterwards, said the outstanding feature - apart from Harder’s obsession - was the teamwork behind him.
This comprised of his family, including brother Gage, friends and workmates, including woolhandler Janelle Hauiti, originally from Ohai, in Southland, and Elton Hokianga, from Hawke’s Bay.
Another big part of the team was Harder’s parents Suzie and Boof, present in the woolshed throughout a day in which supporters and spectators grew to over 150 people.
Harder has been a goal-setter in the woolshed since he first picked up a handpiece.
He shore 100 lambs in a day for the first time when he was 7 years old, 200 at the age of 12, 300 at the age of 14, 400 at the age of 16, 500 at the age of 17, 600 at the age of 18 and 700 at the age of 19.
His record is one of eight notified to the records society for the 2023-2024 year, the first, in the UK last month.
The seven others currently scheduled will all be in New Zealand, from December 15 to February 9, five of them targeting women’s records.
