Sandwiched between her world teams title in France in July and a transtasman test match in Australia later this month Ms Karuariua has won the national finewool, Spring Shears longwool and Corriedale championships, thought to be the first time anyone has completed the treble in one season.
She won the finewool title at the New Zealand Merino Championships in hometown Alexandra on October 5, the longwool title at Waimate a week later, and the Corriedales title at the New Zealand Agricultural Show in Christchurch last Thursday.
No-one else has won all three titles in one season in Shearing Sports New Zealand records dating back to 1991.
Semi-retired multiple World, Golden Shears and New Zealand champion Joel Henare was runner-up.
Mr Henare won two of the three titles in each of the last four seasons.
Ms Karauria has now won 24 open finals dating back to her first, also in the Corriedale championship, in 2016, and was made a Master Woolhandler in 2018.
She will also compete in a transtasman test for the first time in Dubbo, NSW, on November 29, teaming up again with world title partner Sheree Alabaster, of Taihape.
Third place went to 2009 Golden Shears Senior champion Ratapu Moore, originally from the North Island but now based in Marlborough.
Open final: Pagan Karauria (Alexandra) 123.632pts, 1; Joel Henare (Motueka) 159.59pts, 2; Ratapu Moore (Sefton) 220.85pts, 3.
