"It rained and was quite cold, blowing in of the lake [Taupo]," he says.

With each series consisting of two tests, the country with the highest combined aggregate wins the cup.
This year,s New Zealand scored 376.5 in the first round and 385.5 in the second to stay on the path to victory. The competition is conducted over a special course and consists of four obstacles - a gate, a Maltese cross, a ramp and a pen.
Australian rules apply as far as the gate, followed by a New Zealand drive through the Maltese cross and over the ramp, then back into an Australian carry to the pen.
In the New Zealand sections, competitors are allowed to assist their dog more than in the Australian section to further demonstrate their stockmanship skills.
The NZ Sheep Dog Trial Association Trans Tasman Test Series has been running for 30 years, and for fans it remains a calendar highlight.
