But the gap has been closing, Smith winning on the day by just 0.13pts, needing quality points to beat Mutch, who sheared 20 sheep in 16min 37.33sec, first to finish by 15 seconds as the first five all sheared quicker than anyone in last year's Pahiatua final.
The three are expected to be the first three favourites for the Golden Shears Open final, in addition to a Smith v The Field option.
The only change was the emergence of Smith's fellow world record-breaking brother Matthew, who was fourth, home from England to receive his Master Shearer award at the Golden Shears.
Woodville shearer Tegwyn Bradley had his seventh win in his last eight finals to claim the Senior title by just over a point from runner-up, and Gore-based Lionel Taumata. There was a winning margin of just 0.34pts in the Intermediate final by beating French Golden Shears lower grades hope Jeremy Leygonie, and 14-year-old Reuben Alabaster scored his second win of the weekend, a strong prospect to become the youngest to win the Golden Shears Junior title at 14.
The Pahiatua Shears attracted 66 shearers to a Mangaone Valley woolshed southeast of Pahiatua, a huge decline since the 1970s when more than 200 shearers competed.
