There is no current four-stand women's record under World Sheep Shearing Record Society rules formulated in the mid-1980s.
Organiser and former solo record holder Jills Angus Burney says the team are capable of a combined total exceeding 2000, an average of 500 lambs each.
Burney, from Feilding but now living in Masterton, will be joined by Sarah Higgins, of Blenheim, Megan Whitehead, of Gore, Piopio-based Natalya Rangiawha, from Raglan, and mainly South Island-based Amy Silcock, from Wairarapa farming locality Tiraumea.
It's very much about conditions being right on the day – the forecast is for a fine-weather start - but the women won't be short of support, with a significant volunteer force having gathered to start sheep and woolshed preparation on Sunday and Monday, ahead of the quartet's first practice run together today.
Angus Burney said 2300 lambs have been selected, and in a sample wool-weigh shear today before the judges, an average of about 1.3kg wool per lamb is expected, comfortably ahead of the 0.9kg requirement.
Shearers vastly experienced with record attempts are on hand and Angus Burney said: "We had a good line picked - those guys are really pleased with the lambs".
The target flock of 2300 were crutched on Monday. Among the helpers were 12 of the crew of Piopio contractor Mark Barrowcliffe, who helped at a successful three-stand record by three male shearers at Puketiti on December 23.
Angus Burney said the shearers had started physically preparing more than six months ago, although a replacement had had to be brought in after the withdrawal of injured shearer Helga Sinclair.
The bid cost about $15,000 to stage, including a World Sheep Shearing Records Society fee close to $8000 to assist with having the required international judging panel.
The organiser said the bid is about the shearers challenging themselves.
They would be heartened and motivated by the effort of Canadian shearer Pauline Bolay who shore a solo women's eight-hour record of 510 early last month.
