And Papamoa, led by Naomi Davoren in the 40-49 women and Kim Harker in the 50-59 men, finished third, ahead of Mairangi Bay and another Bay club, Whakatane in fifth.
But with their overwhelming numbers and tremendous team spirit, Omanu couldn't be denied - Jol McGarvey claimed overall honours in the 30-39 women but otherwise their performance was all about consistency.
Other special performances came from Omanu's Sid Salek, who turns 83 this month, grabbing third in the 70+ agegroup, while Ocean Beach Kiwi's Greg Larsen won his 22nd consecutive masters beach sprint title at the tender age of 63.
Yesterday's carnival was held in sparkling Autumn sunshine, the perfect prelude to the State New Zealand Surf Life Saving open championships which start at the same venue today and go until Sunday.
