Informed by the expectancy–value theory and the motivational factors influencing teaching model choices, this case study explored three Chinese-as-a-foreign-language teaching assistants’ (L2 Chinese TAs’) motivational engagement in teaching L2 Chinese as a sustainable and lifelong career in New Zealand. Each TA participated in three rounds of semi-structured interviews in the process of data collection. The findings revealed that (1) the TAs’ expectancy was all student oriented, regardless of their different backgrounds; (2) the different values of L2 Chinese teaching contributed to the TAs’ teaching performance and career choices; and (3) the impact of teaching self-efficacy on the TAs’ profession retention was pivotal, but controversial, when taking their previous majors into account. Implications for the sustainable development of L2 Chinese teachers were discussed.
