Now in his 20th season of Open-class competition, Kirkpatrick first won the rankings' Bowen Trophy in 2002, the season in which he ended King Country icon David Fagan's 12-year reign as Golden Shears champion, and has now headed the rankings each season since 2007.
A prolific winner in both the North and South Islands, he's an early favourite for the eight-round selection series which ends with a final in Gore on February. He's also a leading candidate when two machine shearers are named for the world championships in Masterton a fortnight later.
Kirkpatrick won a world teams title with Taranaki farmer Paul Avery in Norway in 2008, but missed out on a place in the team for last year's championships in Wales.
The Carterton event also brought important wins in the lower grades, with Kane Kapene, of Martinborough winning a senior final for the first time, Golden Shears junior champion Michael Rolston, of Levin, winning his first senior title and Manahi Fox, of Masterton, winning his first junior final.
The open woolhandling provided a similar success for woolhandler Choppy Patterson, of Alexandra, who claimed her first Open title.
