Buick now has 24 open final wins to his name, including four national lambs titles and two Australian crossbred Warrnambool Romney Shears titles.
Taihape teenager Reuben Alabaster had his second win of the season in claiming the senior title, with a margin of more than three points over runner-up and Taranaki rookie competitor Andrew Brown, with third place going to Daniel Biggs, of Mangamahu, in his first senior competition since ending last season as No 1-ranked intermediate nationwide.
Saturday's intermediate final was won by Clay Harris, of Piopio, and the junior final was won by newcomer Jessie Sullivan, of Fox Glacier.
It was the second-to-last competition of the pre-Christmas phase of the season, ahead of the new Whangarei A and P Show Shears next Saturday.
