"Matt was going really well, he just cracked on the last lap, but he really deserved the under-23 title.''
McCauley is now preparing for the Tour of Adelaide, where he will race with Australian-based UCI Continental team, Drapac.
The outstanding performance of the day went to Zenovich, who took the win in the under-23 men's race after attacking in the first kilometre over the demanding and hilly course near Arrowtown.
Zenovich, 19, who is riding his first season in the under-23 category, made his move from the start and spent the entire race either out on his own, or in the breakaway.
"It was hard. It was pretty much 150km of wind in your face really. That last little bit was just hell really,'' Zenovich said.
"I don't think there ever really is a race plan, it just kind of happens. I don't think I could've gone any harder.''
Richard Lawson, also of Cycling Southland, crossed the line 59 seconds behind Zenovich to take second, and Pegasus Cycling's Sam Friend took third in the under-23 race.
Jim McMurray made a solo break during the first lap of the men's masters four race, and crossed the line in impressive fashion, over three minutes ahead of second place getter Brent Marryatt (Pegasus Cycling) and Dave Lawson of Papanui Cycling Club in third. This gave McMurray the double after winning the time trial honours earlier in the week.
