When Alfred Domett became Premier in 1862, Bell became Colonial Treasurer once again, and also Minister of Native Affairs. Bell was relatively experienced in negotiating with Māori, and spoke the Māori language fluently. Bell was not particularly active in his Native Affairs role, however, as he believed that the Governor – not Parliament – should have primary responsibility for Māori relations. When Domett was ousted as Premier by William Fox, Bell lost both roles. From 1869 to 1871, Bell was a minister without portfolio.
