Haggerty returned to Hawaii to wrestle with the NWA, and he succeeded in taking the NWA Hawaii Heavyweight Championship from Neff Maivia on February 6, 1964. He held the belt for over two months but lost it back to Maivia in a rematch. While wrestling with the Los Angeles-based Worldwide Wrestling Associates (WWA) later that year, he won his first of four WWA World Tag Team Championships. He teamed with The Destroyer to win the title twice in 1964. In Hawaii again the following year, Haggerty won his final singles title, taking the NWA Hawaii United States Championship from Enrique Torres on February 24, 1965. He held the belt until September 15 that year, when he lost the title to King Curtis Iaukea. He later returned to Los Angeles, where he teamed with El Shareef to win the WWA World Tag Team Championship twice more.
