Bennett, 24, is a climbing specialist who was pipped by his then teammate Hayden Roulston on the line two years ago, while Sergent enjoyed another brilliant 2014 season with several outstanding time trial performances.
But the attention centres on the Avanti Racing team that boasts Bevin, Joe Cooper, who won three stages at the Tour de Vineyards, and the exciting Tom Davison, who raised eyebrows with his powerful performance to finish third behind Roulston and Jack Bauer last year. There's also interest in Commonwealth Games gold medallist Shane Archbold (Timaru), who will move to the powerful German Continental Pro team Bora-Argon 18 this year.
Today's 120.5km women's race looks likely to be decided from a select group that includes Commonwealth Games gold medallist Linda Villumsen, defending champion Jaime Nielsen and her fellow Cycling New Zealand endurance track teammates Georgia Williams and Lauren Ellis, and Wiggle Honda professional Emily Collins.
With the championships moving to Hawkes Bay next year, it is the final chance for Villumsen to win the title in her adopted home in Christchurch, although traditionally she has found her best form later in the year.
Nielsen, who won yesterday's 25km time trial over Villumsen by 11 seconds, will go in as the pre-race favourite after a storming win in the Tour de Vineyards last week, where she won all five stages. Young Christchurch rider Michael Vink, a three-time winner of the national under-23 honours, won his first elite men's time trial title over 40kms, while US-based professional James Oram won the under-23 crown.
