The best heading dogs from both sides of the Tasman will go head to head later this month, as New Zealand hosts the annual Trans-Tasman Sheep Dog Trial Test at the Ashburton A&P Show.

Running over two days from Friday, October 31, the competition will see elite handlers and their dogs from New Zealand and Australia battle it out in the main arena for the Wayleggo Cup, the ultimate symbol of transtasman trialling success.

The cup, first presented by the New Zealand Sheep Dog Trial Association (NZSDTA) in 1994, was inspired by then-president Tony Shield.

Fittingly, this year’s event will be overseen by his son, current NZSDTA president David Shield.

The term “Wayleggo” comes from the traditional musterers’ call - “come away and let go” - used to call dogs back from their work.

This year’s competition promises fierce rivalry.

Although Australia took the title in Geelong last year, New Zealand remains the dominant force, having claimed 21 of the 37 contests since the event began in 1985.

Each nation’s four-strong team is carefully selected through national competitions and championship results.

The New Zealand team is drawn from finalists at the North and South Island championships, while Australia’s representatives earn their place through a national qualifying series.

David Shield said the test represents the pinnacle of heading dog competition, bringing together the finest handlers and dogs from both countries.

“The rivalry is always intense; these are the absolute elite of the sport, and every run counts. Each competitor gets 15 minutes to complete the course, and the standard is always exceptional,” explained Shield.

The course itself is unique, blending both countries’ trialling styles and rules. Dogs and handlers must navigate a gate, Maltese cross, ramp, and pen, alternating between Australian and New Zealand rules along the way.

Spectators at Ashburton can expect two days of world-class skill, teamwork and tradition and a fierce contest for transtasman bragging rights.

The 2025 New Zealand test team will be captained by Mark Copland & Guy (Canterbury) along with the fellow team members:

Leo Jecentho & Jake (Waikato)

Lloyd Smith & Code (North Otago)

Ben Millar & King (Canterbury)
