The first new addition to Aquatica following its 2008 debut, Omaka Rocka opened in March 2010. The ride features two slides, which share a tower with the existing Whanau Way slides. The more recent additions are ProSlide Topsy-Turvy models, and include a series of three "funnels" where riders swirl in the current before being sent on down the next section.

Guests ride in two-person rafts and experience "near weightlessness" when traversing the funnels. Portions of the ride are enclosed, although the slides themselves are semi-transparent to allow guests below to see riders travelling down them. The name Omaka Rocka means "rocking river" and originates from the South Seas.
