In 2009, Wada returned to New Zealand and settled down in Auckland. Soon afterwards, she formed a punk-rock-ska band called Miho Wada and the Shit Fight, and the ensemble toured for the next couple of years. In 2011, she formed the new six-person band Miho's Jazz Orchestra, and the group raised funds for Christchurch earthquake recovery work. Miho's Jazz Orchestra has continued to perform steadily since then, touring New Zealand, Australia and Japan, and the group's musical style is described as "a combination of Afro-Cuban and J-pop, influenced by contemporary jazz".
