"This will be my last time in a New Zealand transtasman test team," he said. "I have new commitments with my boys so I would like to make it a good one."
It's been a stellar career for Henare who had his first open-class woolhandling win at the age of 15, and whose record of now over 100 wins includes four World titles - World championships individual and teams titles in 2012 and 2017.
It also includes a record six consecutive Golden Shears open titles, and four wins in the New Zealand Championships open final. He's also had eight wins in the Otago Shears' New Zealand Woolhandler of the Year final, the first five in a row before he'd turned 21.
"I've met a lot of great people in my short," he said - oblivious to the fact that he has been competing, "hard-out" (as the saying goes), for more than 14 years, since the 2004-2005 season when he won a New Zealand Junior title at the age of 13.
"They've all helped me to be the person I am today and I thank them all 100 per cent."
The odds are heavily in favour of a win in his last test in Australia where he partners with 2008 world champion and eight-times New Zealand Shears open champion Sheree Alabaster, of Taihape.
New Zealand has won all 12 transtasman tests in which he's competed dating back to his first at Hay in New South Wales in 2008.
The black-shirts will be going for a sixth win in a row in the annual home-and-away tests, Australia having last won in Masterton in 2015. Australia will be represented for the fourth test in a row by 2017 World Championships pairing of Sophie Huff and Mel Morris.
Canterbury shearers Tony Dobbs and Allen Gemmell will be favourites to clip their way to New Zealand's 10th blades shearing test win in a row, up against regular Australian pair Johnathon Dalla and Ken French. Australia is yet to win in the blades tests since regular matches began in 2010.
It will be a different story in the machine shearing test where possibly New Zealand's strongest-ever transtasman team, comprising 2017 World Teams Champions John Kirkpatrick and Nathan Stratford and 2014 World Champion Rowland Smith will be out to stop merino shearing guru Shannon Warnest from leading Australia to a third win in a row.
Australia have won 20 of the 31 tests since the South Australian shearer first took part in 2000, have now won 33 of the 63 tests since regular transtasman machine shearing contests started in 1974, and Warnest and teammates Daniel McIntyre and Jason Wingfield won at Bendigo last November and in Masterton last March.
The New Zealand team is managed by shearing judge Peter McCabe, of Tauranga, and the woolhandling judge is Linda Tarrant, of Taumarunui.
