The women's line-up includes series leader, 17-year-old Katie Wilson (Mount Maunganui), who will resume her battle with 18-year-olds Natalie Peat (Papamoa) and Danielle McKenzie (Mairangi Bay).
With small waves forecast, former-New Zealand ironwoman titleholder Rachel Clarke should also feature with her accomplished swimming background.
There will also be interest in the return to competition of Mairangi Bay's Maddie Boon, who has spent much of the season travelling overseas.
McKenzie and Shergold will also join other recent New Zealand representatives at the two-day carnival, including world champion national team member and Olympian Steve Ferguson (Piha) and Papamoa's rising star, Ben Johnston.
Northland clubs will be represented by an eight-strong Ruakaka squad racing on their home beach and Omaha also has a couple of competitors racing.
Red Beach and Orewa have the largest squads heading north, with nearly 100 competitors each, including surf boat and canoe crews.
There are also nearly 60 master athletes racing, with a full programme of events planned over the two days.
