No, your wrong, its Kaiten.I think its pretty obvious Hinatas new move is not the Kaiten, first of all, Neji does not recognize her footwork when she avoids running into him (thus it is implied that that was the footwork for the move), and second, when she uses the move to defend against the kunai, they are not reflected and blasted away like the kaiten would do, they were litterally bent and broken and fell at Hinatas feet, when Neji deflected kunai with the kaiten they went flying away, and remained in good shape.
